Infrared shadow after color depth mapping?

hello everyone;
So I used the V2 sensor and did my own calibration using the checkered board method and I was able to successfully map the depth map onto the RGB image. Below are the images:
So the second image is the depth map mapped on to the resolution of the color image. It seems to overlay perfectly except for this "hole" behind the second cardboard on pixel around 1200.
Why is that? Is that a case of IR shadow? is that why or is the calibration off? everything else seem to match pretty well.

Hi,
I'm also trying to do my own calibration of the RGB/IR cameras as well as a calibration of one versus the other. From what I understand you have achieved just that, did you notice any improvement in depth accuracy? And in color to depth mapping?
I like this approach for depth calibration:

it's further down the processing pipe, so maybe it can account for other inconsistencies? I might go and buy some cheap plexiglass...

W500 - switches to 16-bit color depth after disconnecting LCD TV

Hi guys,
My W500 always changes the screen color depth to 16-bit when I select "Notebook only (factory default)" on Fn+F7 menu, after watching movies on LCD TV. It happens both on Display Port and VGA connector. I have set "separate displays" (no desktop cloning). I remember having the same issue with old T61p. How to prevent that from happening?
cheers,
Mika

@tester2002,
Do you have the latest video driver installed?
can you try this.

Color depth of the mouse cursor

Upgraded to srss 4.2 yesterday and discovered the addition of Xrender support. After enabling it the mouse cursor switches to an animated one. This looks really horrendous, since the mousecursor is displayed in black and white (1bit color depth). Does anyone know how to increase the color depth of the mouse cursor? The screen is configured with a color depth of 24 bits

Gnome 2.16.0 on RedHat 5.3 with Metacity as windowmanager. The mouse displays just fine, but is was real bw non animated before Xrender. Now it is animated and the animation is converted to 2 bit, including dithering for shadows. Regard this as an esthetical bug. A resolution would be to search for a 2 bit mouse theme (or create one)

AMD FireGL GPU + Creative Cloud app = Color Depth & other Issues

Hello, I am writing this post to help anyone who may have ran into the same issues I am seeing with my AMD FireGL graphics adapter when using the Adobe Creative Cloud app on a windows 7 PC.
I ran into a problem installing and setting up the Creative Cloud app on my new workstation that has an AMD FireGL graphics processor.
First off, the system is new (dell precision m4800, with an AMD FireGL V M5100 GPU), and has all the most current drivers and updates available.. that is to say, this is not a hardware issue.
The system operates just fine outside of the Creative Cloud app, but when I installed and attempted to login to Creative Cloud for access to download Illustrator, etc., the Creative Cloud app would open up and then only display a blank white page. No graphics, no data, just white.
When I got stuck at this point I called Adobe support and spoke to a rep who had seen the issue before. The rep worked around the blank white page in CC by loading the windows device manager and manually disabling the AMD FireGL GPU device to re-install and login to the Creative Cloud app.   This temporarily forced windows to use the default/dummy VGA graphics driver supplied with windows.   With windows using the dummy 256-color vga driver we were able to get the creative cloud app running and get me logged in to install my design software. HOORAY!--or so I thought....
At this point I assumed the issue was resolved, but I found that there was a new issue popping up every time I rebooted my system. Windows would load and log me in using the 32bit color depth setting, but as soon as the Adobe Creative Cloud app started up, my color mode would switch to 256 colors... D`oh!
Obviously I don't want to run at only 256 colors, and neither should you! Adobe, why does my color depth change to 256 colors every time the Creative Cloud app is loaded?
If you want to temporarily reset the color depth to 32bit, you can go to Control Panel -> Display -> Adjust Resolution -> Advanced Settings -> Monitor Tab -> & select "True Color (32bit)" from the Colors drop-down menu. Using this method will allow Adobe Creative Cloud app to continue running 24/7, however this is only a temporary fix, which will need to be applied every time the system is rebooted, or any time a user logs off then back in.. Frankly, its a bit of a PITA, so why bother?
The permanent fix is simple.. go to Start -> & do a Search for "msconfig".   Once found, run the msconfig utility and switch to the "Startup" tab, where you will be presented with a list of boot time startup items. Find the one labeled "Adobe Creative Cloud" and disable it by removing the check mark from the corresponding check box.   Then click OK. You will be warned that a restart may be required.. go ahead and re-start.   This time, when the system boots, Adobe Creative Cloud will not load, and your color depth will remain at 32bit. YAY!
If need be you can always load up Creative Cloud manually from the start menu if you need it, but it will knock your color depth back to 256 colors. Thus far i have had zero issues using adobe photoshop or illustrator without first loading the Creative Cloud app, so it isn't required. If i need updates or need to access other features within the Creative Cloud app i can, but it doesnt need to run 24/7 to use other adobe apps.
The short explanation is that Adobe is failing to fully and properly support the AMD FireGL graphics platform. The adobe rep i spoke to essentially said the same thing, but made certain to blame the graphics device and not adobe software--sure thing boss.   The truth is that the FireGL and its varients have been on the market as long or longer than the nvidia products that are supported fully by adobe.
It is clear that Adobe has made a choice not to fully support AMD Workstation graphics (FireGL) since not only is the Creative Cloud app broken and causing problems, but also no graphics acceleration features work in any of my installed adobe apps.. I basically get a message saying "please us a supported graphics processor". Seriously, how is FireGL not "Supported"?
I am not an AMD or FireGL fanboy.. Frankly I cant stand AMD graphics adapters and I genuinely prefer nVidia on my personal systems. At home, my 5 year old $100 nVidia gaming card is fully supported in all the adobe apps..
At work, however, I have no choice what hardware is provided to me and this lack of FireGL support has negatively impacted my productivity more than once. Admittedly, nvidia has much more market share than AMD in the workstation graphics realm, but that does not mean adobe should just ignore AMD completely!
Hopefully this post will shed some light on issues with Adobe Creative Cloud app and FireGL graphics cards that others may be experiencing.
Good Luck!

Minor correction... I called my GPU the FireGL, which is the old market name.. The current, proper market name is FirePro.. same line, just new branding after AMD purchased ATI.

Does duplicating layers from an 8-bit PSD reduce the color depth of a new 16-bit edit?

I have been using several versions of Photoshop over the years starting with CS3, then CS6, and finally CC. Through 2012, all my RAW files were converted using 16-bit color depth in ACR. However, in examining my files recently, I noticed all were in 8-bit color-depth, which likely happened once I upgraded to CS6 and ACR left 8-bit as the default. As such, I now have hundreds of images that I wanted to edit in 16-bits that have been converted to 8-bit starting with my ACR export. The files are all RAWs from cameras like the Canon 5D, 5D Mark III, Olympus OMD EM5, and Sony RX100.
I have 8-bit PSDs of my edits of these files which contains multiple layers. I use features from the Nik and Topaz collections for noise reduction, contrast enhancement, black and white conversion, and sharpening. I also use layered Photoshop features like Selective Color. I want to know if I can simply duplicate the layers from the 8-bit PSD files onto a new 16-bit RAW converted background layer rather than re-edit each and every file. There would be no change in the crop of other reasons why the layers would not match up, but I am concerned that duplicating those layers might throw away the benefit of moving to 16-bit since they were created in an 8-bit color-depth.
As a test, I looked at a few files where I had pushed the shadows and colors to an extent and duplicated the layers from an 8-bit conversion to a 16-bit conversion and could see no difference. I am not sure if this is because Photoshop has become very good at reducing color-depth without a perceptible difference or if I am throwing away information in moving the layers.
I work off of a fairly modern computer and a top-end Eizo CG276 self-calibrating monitor and good video card. I am extremely sensitive to color and shade changes as well.
Thanks for any help, I am a bit stressed at the thought of re-editing hundreds of files from step 1, but it is important to me that I not throw away color information and it is better I start re-editing now rather than years from now.

While raw file contain a 8Bit jpeg previews image in some color space. The RAW sensor data is not a color image and has no color space and the bit dept of pixels depend on the manufacturing. Most sensor produce one value for each pixel 10 to 14 bit seems to be common. Sensors only measure the light intensity not color. If front of each pixel sensor is a color filter which lets Red or Green or Blue light be measured for intensity.
A RAW converter can convert your sensors RAW data into a color RGB image in any color work-space in 8 or 16 bit color depth. No Adobe update went around and scanning your computer looking for 16bit color depth images and convert all of them to 8bit color. Your ACR workflow settings may have been change from 16 bit color to 8 bit color by you or set to 8bit by some update or script used. So you current ACR work-flow setting may be converint tou raw datya into 8bit RGB images. As long as you have you raw files you can reprocess these to produce 16Bit color RGB Image by makinf the proper ACR work-flow settings. You can also change your 8bit image to 16 bit image mode. However this will not recover any color quality lost or posterization that has set in.. It will give you a bit more latitude using Photoshop filters which may help you not get banding posterization.

Display-Color-Depth

Hi there.
After an application-crash (After Effects) and cold restart my monitor-color-depth suddenly switched from millions of colors to maybe several hundreds of colors. I've tried cleaning the caches, throwing out preferences-files (out of library) and also resetting the color-depth by using third-party-applications. Still not working. I suppose it's some kind of problem in one of the preferences-files in the library, but I don't know which one.
The "About This Mac" section shows that the monitor would show some "Millios Of Colors".
As I can not work like this I made a new user-account. In the new user-account everything runs smoothly but for sure I would like to use my old user-account with all my settings and preferences instead of switching to a total blank one that I have to modify again to fit my needs. Does anyone have an idea what could be wrong or how to succesfully force the display to display millions-of-colors again?
When I log into my old user-account the display first shows normally, then switches to "hundreds-of-colors" after a split-second. Is there any way to slow down this process and monitor which preference-file the computer is loading in exactly this moment?
Also weird: when I connect to my old user account via remote access / screensharing (vnc://...) then the display looks normal from the remote computer.
Any ideas would be welcome. Don't know what else to do...
Cheers, Aeiou

What does it say if you go to About This Mac -> More Info -> Graphics & Displays -> Pixel Depth
1: Try resetting the PRAM.
2: Go to System Preferences -> Displays -> Color -> Select another profile or calibrate
3: Go to System Preferences -> Universal Access -> Slide the Contrast bar all the way to the left
Might end up just being a plist to snag though.

Solaris 10 - Changing default screen color depth

Hello,
I just upgraded a Sun Blade from Solaris 8 to 10. I have a rather old image display application (ftp://east.la.asu.edu/pub/software/pw-5.23.tar.gz) that is absolutely essential for my work, and it will not run under Solaris 10, either on the CDE or jave/gnome desktops.
The executable for this application was compiled using gcc on Solaris 8, and ran fine on Solaris 8 CDE (v1.4.3?) with the "Most colors for applications" color setting in Desktop Color prefs. With that setup, the application allocated 216 colors when starting up, which was sufficient. If the application could not allocate enough colors, it would use its own private color map, which caused window "flashing," but that was OK.
Under Solaris 10 CDE (v1.6.3) and gnome, the application cannot allocate enough colors, and cannot even start with its own color map.
I re-complied the application on Solaris 10 using Sun Studio 11, and the same problem occurs with the new executable.
I think that the problem may be related to default color depth. Right now, with xwininfo, my Solaris 10 CDE xterms are 24-bit true color. Unfortunately, I think that I may need to set my default color depth to 8-bit pseudocolor for the application to run. How can I change the default color depth of the CDE and gnome desktops to pseudocolor? I know that the application works on HP-UX CDE with the default depth as pseudocolor.
I cannot remember if I had somehow changed the settings for color depth on Solaris 8 to get the application to run. I do know that the xwininfo results for a Firefox browser window running on my Solaris 8 CDE desktop was 24-bit true color. I hope very much that this will be the case if I change my default depth to 8-bit on Solaris 10.
Any help that anyone can provide would be GREATLY appreciated. I am dead in the water without this imaging application. I am a member of the Sun Developer Network, and I don't know if I should post this message somewhere on the Developer Forums. Please let me know if I should.
Thank you in advance!!!!!

Hi,
In my first post there is a link to the code I am talking about. The code is public and available. It was created by Noel Gorelick at ASU. It is based on having an 8-bit Xserver running. There are few users of this code, but I completely agree with you that a new generation of unix-based imaging code needs to be developed that is system and Xserver independent. Optimal code should detect screen depth and open windows with desired color depth automatically, without "flashing.". That way, it could even run under Gnome, which allocates all but 18 8-bit colors for the desktop. Under CDE, the code allocates 224 colors for itself, which is great. The above code will create its own colormap if it cannot allocate enough colors, but there is flashing in that case. Have at it if you wish.
Best regards,
Sparcmaster

Did iSight change my color depth?

I just installed an iSight camera and shortly after, I realized that my monitor's color depth had downgraded somehow.
For instance, the flat greys on the left and right of a Safari window toolbar come out like greyish teals; and skin tones in photographs and video appear posterized and flat due to the lack of colors.
I've checked my display settings in System Preferences: the colors are still set to "Millions". I even tried unplugging the iSight... still nothing.
any thoughts? Was it a Quicktime or OS update?

Installing iSight did not change my display's color. I do not know anything you listed that might have caused your color shift.
I apply all updates to QuickTime and Mac OS and have never had such a problem. Do you use an update process such as How I Update My Mac OS X?
Have you recently performed your regular Mac OS X maintenance? If not, do so now. That may restore your settings.
Have you (or someone else who has access to your Mac or your Monitor) changed any monitor settings? You do not say what monitor you use. Perhaps it has external adjustments that may have been bumped out of adjustment?
You might also want to check your System Preferences > Displays > Color settings to see if it has been changed by someone.
If none of these things help you, try a search in Mac mini Discussions for "display color" (without the quotation marks) and see some of the suggestions there. The Mac mini users who post there may have better suggestions for you than I do.

Change Color Depth Remotely?

Does anyone know how to change the color depth on multiple clients, using ARD, without restarting? Is it a simple UNIX command?
Example: A student runs an OS9 application that changes the color depth from Millions to 256 Colors. When you try to Observe that machine, after the student has quit the program, the picture is all garbled (ARD has trouble viewing 256 colors).
I want to be able to remotely change the color depth back to Millions from 256 Colors without restarting. Can this be done??

You can if you install cscreen (freeware) which allows you to change resolution and pixel depth via the command line. Once installed (and it can go pretty much anywhere), you just use the Send Unix Command function with the path to the cscreen utility and the appropriate settings. Here's the full syntax:
Usage: cscreen [-d <depth>] [-x <width>] [-y <height>] [-r <refresh>] [-s <display>] [-v] [-m] [-f] [-l] [-h]
[-d <depth>] : specifies the bit depth (bits per pixel)
[-x <width>] : specifies the width in pixels
[-y <height>] : specifies the height in pixels
[-r <refresh>] : specifies the refresh rate in Hz
[-s <display>] : specifies which display to use (defaults to main display)
use a as the option to -s to specify the action on all displays
[-v] : display valid modes (use -s to specify display or nothing for the default)
[-m] : require an exact match
[-f] : forces settings (ignores safety mechanisms; USE AT YOUR OWN RISK)
[-l] : lists the current displays and modes
[-p] : sets the requested display to have the menu bar
[-h] : displays the usage

Color Depth Change/Banding

With iPhoto 6, whenever I try to edit a RAW image from my Canon cameras (.crw or .cr2), the image loads and then after a few seconds it appears that the color depth drops. This results in heavy banding and color shifts.
I was able to edit just fine using iPhoto 5. This problem does not effect .jpgs.
I believe I've seen a discussion similar, with a possible fix accomplished by deleting the Flip4Mac files (supposedly wreaking havoc with QuickTime or something). I tried that but no fix.
This is happens on two Tiger machines running the latest updates.

Followup:
I created a new account and copied a Canon RAW (.crw) file to the shared folder. I then imported that file into the iPhoto library in the new account and opened it to edit (full screen mode). There didn't appear to be any of the banding/solarizing effect.
Does anyone have any idea why this would be an account specific problem?
I had also previously (the day before) downloaded the latest version of the Flip4Mac software and installed it, with no change to my problem.

Problem posting images on the forum (color depth)

I was posting an idea on CVI idea exchange board and was continuously getting a generic error ("Codice di errore: caricamento non riuscito" which means "error code: unsuccessful loading") while trying to add an image.
After several studies and attempts I realized that the problem is not in the image size or name or whatsoever element but rather in the color depth: it arises with 32-bit images, while you can post 24-bit images without problems. This applies to other forum boards as well (just tested on CVI board and this actual message), I suppose it is a general rule.
I don't seem to have noted any note on this in the forum help: there exists some documentation on which objects the forums accept as attachments? You know: file types, image types and characteristics, object sizes and so on...
Proud to use LW/CVI from 3.1 on.

Font Smoothing/Clear Type disabled on RDP Session, color depth low

Hello
One of our customers has a new laptop Asus G771JM-T7021H with Windows 8.1 on it. The graphics, font etc. is good as long as he works locally. When he connects to the terminal server (2012R2) via RDP, the resolution and font is hardly readable. It seems that
the clear type is disabled, everything is blurry and pixelated. The color depth seems to be very low. We've checked the RDP-configuration and the graphic card driver but couldn't find anything wrong.
Any ideas?

Windows explorer keeps computing items after accessing a mapped network drive

Our organization has decided to upgrade to windows 7 but we are running into a problem with windows explorer green progress bar hanging after accessing a mapped network drive. When you try to go back to computer or access the control panel after going
3 or more folders deep into the mapped drive, windows explorer just keeps searching.
When you expand the arrow in the address bar it states that it is computing items and never stops.
The only way around this is to right click on libraries and select reset back to defaults and everything is back to normal.
We are deploying this image of windows 7 to over a 1000 computers and we cannot have this problem lingering, does anyone have a solution to resolve this issue. This does not happen in Windows XP.
We have tried to turn off windows search and remote differential compression and this does work but the problem is that you lose all search capabilities in windows. So windows search needs to be enabled. We also tried to adjust the MTU, change GP settings,
and nothing seems to work except to turn windows search off or reset libraries back to default.
We also did some research online and there are so many people experiencing the same problem, with no resolution expect they have to go back to Windows XP. That is not an option for us.
Please help us we would really greatly appreciate it.

Hi,
The issue could be related to searching and indexing feature in Windows 7. I suggest rebuilding the indexing files.
Click Start -> Type
indexing options in the search box -> Advanced -> Index Settings tab-> Rebuild buttion.
For more information, you can refer to:
http://windows.microsoft.com/en-us/windows7/Change-advanced-indexing-options
If the issue persists, you can perform the following troubleshooting steps.
1. Go to update your network adapter drivers and BIOS from manufacture's site manually.
2. If any router is involved, please update the firmware.
3. Perform a System File Checker.

How to execute an ABAP Mapping after a Java Mapping

Hi, i have found a Bug in XI and SAP said to me that the only solution is to execute an ABAP mapping after my java mapping.
I have an IDOC to FILE scenario
Could anyone orient me on what do i have to configure, so after my java mapping i can execute an abap mapping ?.
Do i have to use process integration?
thanks
Mariano.

i have developed a Java mapping originally, but XI has a bug. When you do not write anything to the outputStream XI instead of writing an emtpy file writes a file containing one byte ( 0x00 ) and this is a problem.
SAP said to me that they will not fix this issue so they recomend me to create an abap mapping after my java mapping that will send no information if it receives this byte (0x00) and if not it will write all the information as received.
My doubt regarding putting several mappings in the interface mapping configuration is this...
Actual configuration:
SOURCE MSG A -> ORIGINAL MAPPING -> TARGET MSG B
Proposed configuration
SOURCE. MSG A -> ORIGINAL MAPPING -> TARGET MSG B
SOURCE. MSG A -> PATCH MAPPING -> TARGET MSG B
I dont understand what receives de "patch mapping" it receives the structure from TARGET MSG B?

N95 v21.0.016 after using Nokia Maps 2.0 Beta on v...

After updating software Nokia Maps returns to v1.2 wk48 b01 and of course maps in E:/Cities need to be deleted and old maps downloaded using Maploader v1.3 after running Nokia Maps to define folder structure. However on a microSDHC with 708.5Mb space left for maps(Maploader definition) it allows me to download and install a 20Mb map but after downloading a further 120Mb map it won't let it install with the message "Your local drive might be full or your access rights are insufficient".
This is of course great news when you've wasted about an hour downloading it!

Hi harrykaa
Essentially so that I am aware of the problems (if any) experienced by users of N95 with the version of Nokia Maps pre-installed in v21.0.016
The answer to my problem was to replace the existing "diskcache" folder in "Cities" with one I found on an older memory card, just wish I had thought of this solution sooner.
