Why I can't subtract two images in imaq vision builder?

Hi,
I have many times tried but failed to get the objects in a image by subtraction with another image which is background, in imaq vision builder(ver. 6.0). I totally can't use the "operators" command under "greyscale" to subtract the two images becauee all commands under the "greyscale" are always unactivated after two images have been stored in 2 idfferent buffers. I really don't know why and this vision builder is so difficult to use, unbelievable! I followed the instructions in its Help and it's quite simple but I totally failed to make this operation!
Two samples of images have been attached and maybe it's very ease for you to filter out objects(fibers) by subtraction each other. Show me your scrip
t if you can. It's urgent to me.
Or the idea of the way I thought for filtering the objects is wrong? Point out please if you know.
Thanks and Merry Christmas and Happy New year!!

Okay, this is not quite as straightforward as it could be, but you can do image subtraction in Vision Builder. The basic idea is as follows:
- select first object image and copy it to buffer 1
- select "image >> get new image" and load your background image from a file.
- put this in buffer 2
- retrieve object image from buffer 1
- perform subtraction. Even though these images appear to be greyscale, they are actually saved as 24-bit RGB images, so you need to use the color operators instead. Vision Builder will only allow you to select steps that are valid for the image you have loaded. You could extract the luminance plane from all of your images to work with 8-bit images if you like.
I have attached below a background image, several object i
mages, my script, and the results of batch processing. You will need to edit the "get new image" step with the correct path to the background image on your machine.
Bruce is right though. This is a bit easier in LabVIEW.

Why i can't see table, image, attacth files in meeting request mail.

Hi, I'm Narongdech
i have a little question in outlook 2013. Why i can't see table, image, attacth files in meeting request mail. i try make a new meeting request for my partner. but them can't see new mail in the correct format.
below,This is a image in my outlook 2007. i try to make this format. Please Help me, and let me know that.
Thank you.

Hi Narongdech,
What’s your Exchange server version? I have tested to send a meeting request to my colleague with a table, a PNG picture and a word attachment in my Outlook 2013 with Exchange 2010 environment. And it can be viewed well.
Please check whether the issue happens to all Outlook 2013 users or some specific ones. We can close Outlook and send a meeting request with pictures and attachments in OWA to have a test. If the OWA test returns everything is OK, the issue may be related
to Outlook client. Please run Outlook in safe mode and disable all related mail software to check whether the issue persists.
Thanks,

Why You Can't Load Some Images On Your 5th Generation ipod

Why You Can't Load some images on your 5th Gen ipod.
- OK here is the scoop: I could not load some images on my 5th gen ipod and yet other images would load no problemo. Images were JPEG, jpg, PSD (all approved image types for the 5th gen ipod)
- After doing several tests like restoring the software on the ipod, reinstalling itunes I still could not find the problem, then I noticed as soon as I would open an image in Photoshop CS2/CS3 that was otherwise loading on the ipod no problemo, when I would save that same image in Photoshop the image would not load in my ipod.
- So after playing with several settings in Photoshop I found the problem:
-In Photoshop go to File handling:
-Image Previews:
- And click on:Never Save
You do not want to save a photo with a "Image Preview" when saving any file type that you want to load on your 5th gen ipod. it would seem the ipod will not accept any images with a "Image Preview" embedded into the file, JPEG, PSD, jpg etc.
I hope this will help some of you because I just waisted a whole day to find this out the hard way.
Cheers,
Mac Fans
BTW I use a Mac Pro/Intel OSX Tiger 10.4.9

Also I just found out when you are saving an image in Photoshop uncheck the " Embed Color Profile" box.
So do not embed your images with a "Preview" and DO NOT embed a "Color Profile" when saving images in Photoshop or the images MAY not load on your ipod.
Have Fun

Why i can't see any image on flickr. That happens most of the times but not always? Both Safari and Firefox

Why i can't see any image on flickr.
That happens most of the times but not always?
Both, on Safari and Firefox i experience the same problem!
I reseted Safari but seems to be useless

You can use these steps to check if images are blocked:
*Open the web page that has the images missing in a browser tab.
*Click the website favicon ([[Site Identity Button]]) on the left end of the location bar.
*Click the "More Information" button to open the "Page Info" window with the Security tab selected (also accessible via "Tools > Page Info").
*Go to the <i>Media</i> tab of the "Tools > Page Info" window.
*Select the first image link and scroll down through the list with the Down arrow key.
*If an image in the list is grayed and there is a check-mark in the box "<i>Block Images from...</i>" then remove that mark to unblock the images from that domain.

Setting maximum number of image buffers in MAX in IMAQ vision builder

To aquire large number of images using duncan Technologies Camera (7f/s) on IMAQ PCI 1424 i'm supposed to set the maximum number of buffer images in MAX(Measurement and Automation)in IMAQ vision builder. But i do not see the option for specifying the maximum number of image buffers under the properties of PCI 1424. Please advise.
Thanks in advance.

The setting is somewhat difficult to locate.
In MAX, select "Tools" on the main menu bar. Under that, select "IMAQ". The only option that comes up is "Max number of buffers".

Can't join two images using imagetoimage

Hello forum users!
Well I have spent a good portion of my weekend trying to get this VI to work and I am oficially out of ideas...
I'm using DataSockets to extract images from the web and I'm trying to join these two images using the ImageToImage function of IMAQ.
The images are extracted just fine but when I try to join them all I get is the first image!!!
What am I doing wrong????
My VI is attached.
Some test considerations:
To extract the images be sure to add [text] to the end of the html line
This VI only works with http and not https (DATASOCKET limitations)

Reading TIFF images without IMAQ vision

Hi,
Is there anyway to read TIFF images with LV 7.1 but without IMAQ vision? I know it's possible for PNG, BMP and JPEGs, but seems impossible to read TIFFs without IMAQ Vision.
Thanks.
Kian

LabVIEW doesn't do this automatically, but maybe someone has a VI they're willing to share.
Another possibility would be to use an external program to convert the TIFF to another format (BMP for example) and then to read in the BMP picture.
If you're looking to write something yourself, then this might help.
Hope this helps

Why I can't connect two edge to origin ?

-> Origin = 192.168.1.10
If I start edge#1 before edge#2 I can request stream from
edge#1 but edge#2 it not work.
If I start edge#2 before edge#1 I can request stream from
edge#2 but edge#1 it not work.
I try to check about max connection for edge server in
vhost.xml at origin server but config is
<MaxEdgeConnections>-1</MaxEdgeConnections>
I don't know why about this ploblem.

Can someone please help me out...
I am trying to display (Result1 - Result 2) on my front panel. Result1 and Result2 will change with time.

Move result 1 and result 2 out of the case structures and subract them.
Right now result 1 or result 2 only get written to if its respective comparison is true. What do you want to do with the math if either comparison is false? You haven't defined your problem clearly enough.

Basic java. I think that you need to read the tutorial... ;-) http://java.sun.com/docs/books/tutorial/
BAD (yours): you are comparing objects (ref to objects -> always differents even if there contains the same thing)

Can you use two images in the "flip" transition?

I want to use the flip transition to show Image 1 spinning and turning into Image 2. Is there an easy way to do this? Thanks.

The flip transition flips the whole slide rather than fliping the image on the slide. The effect is more like a page turn than a "flip"
this is an exaple using a shape, but it will work with any object on the page if sized and positioned correctly
place the image on the first slide
duplicate the image
paste it on the second slide
change the colour of the shape
set the transition on the first slide to Flip in Inspector > Transitions

Why I can not get the image file of component?

Hello,
I tried to get an image file from the component. After I run the code below, there is not any new file created. Could you tell me what's wrong with it?
Rectangle d = this.getBounds();
BufferedImage bi = new BufferedImage(d.width, d.height, BufferedImage.TYPE_INT_RGB);
try {
ByteArrayOutputStream boutstream = new ByteArrayOutputStream();
// save it to file
FileOutputStream fimage = new FileOutputStream( new File( "image.png" ) );
boutstream.writeTo(fimage);
fimage.close();}
catch (Exception ev){
System.err.println("error making jpeg image: " + ev);
ev.printStackTrace();}

BufferedImage bi = new BufferedImage(d.width,d.height, BufferedImage.TYPE_INT_RGB);Straight after the above line you need to put this line:
d.paint(bi.getGraphics());
This is what was suggested to me in this thread(http://forum.java.sun.com/thread.jsp?forum=57&thread=369379) anyway, and it worked for me!
