Thanks for you interest in this post!
It doesn't seem that I have access to these functions from my version. I came with a partial solution to this problem which consist to use a theshold on a color and eclude the possibility to have a grey pixel (R~G~B).
Now, the problem I have is to calculate the centroide that I believed could be easy to identify as the point the closest to all the others (point with minimal distance to the ovther points of the cloud). Unfortunately, the calculation of all these distances takes for ever when processed with multiple loop. Is there any fast function to calculate the center of a could? That will be to replace the script in the VI attached here.
Here are the VIs and a JPEG to illustrate the issue. The goal is to find the center of the red star.
You can compare the conditions
(1) Threshold for red=40 ; threshol grey filter=0.75; grey filter = off;
to
(2) Threshold for red=40 ; threshol grey filter=0.75; grey filter = on;
to
(3) Threshold for red=99 ; threshol grey filter=0.75; grey filter = off;
(2) & (3) give good detection showing that excluding the grey condition is worthy....
but the position of the center identified in the star is not idealy located .... any idea to improve this with a low computing cost would be verymuch appreciated! I'd like to have this system quick enough to work during the video capture (on line).
Thanks,
Olivier
PS: you may need to press twice on calculate to have it updated....not sure why....

After turning an image black and white, how can I color in a certain area?

After turning an image black and white, how can I color in a certain area?

How did you change it? Did you make your B&W on a separate layer? If so, just erase the part of the layer you don't want, or add a layer mask and paint with black over the parts you want to hide.
If not, then you can copy/paste the original photo (you will need to press ctrl+A/cmd+A to select all before you can copy) into the new image. From there it depends on the relative proportions of B&W. Arrange the two layers so the one with the most area that you want to keep is on top, and either mask out the rest or just erase it away.
For future reference, an easier way to do this when starting from scratch is to use the smart brush. Choose a black and white conversion style, turn on the inverse checkbox and paint over the part you want in color. The rest of the photo turns black and white, leaving what you paint over in the original colors.

What program are you using - Photoshop Elements or Premiere Elements, what version, and on what computer operating system is it running?
If you are using Photoshop Elements and not Premiere Elements, you have posted in the wrong forum. In that case, you want to post in the Adobe Photoshop Elements Forum. Somehow your thread got posted in the Adobe Premiere Elements Forum (video editing).
Photoshop Elements
If your program is Premiere Elements, I will give you a how to for what you want to do using Premiere Elements for your video project.
We will be watching for more information from you.
Thanks.

HP 8500 All-in-one printer - how can I print in black and white only (to save color ink)?

I want to be able to select the option of printing in black and white only to save color ink. How can I do that?

What operating system? You can generally find an option for "Print in grayscale" and "Black ink only" in the Color or Advanced tab of the Printer Settings.
Some color ink will still be used to keep the printheads from clogging, see here for information. (The Officejet 8500 is an IIC printer in the vocabulary of that page.)

Making pictures that are black and white but still have color someplace(s)

Is there a way in aperture to make pictures black and white but still leave color on some objects. for example, having a picture of someone holding a glass of red wine and having everything except the wine black and white?

A couple of ways this can be done
- non destructively:
Use the Color adjustment to reduce the saturation of all the colors you dont want,
and leave only the saturation of the saturation of the color you do want.
Use the Ranges to more selectively choose the right color you want to leave.
- destructively:
Use the Dodge&Burn plug-in from Apple.
Set the brush to Desaturate, choose its strength and size appropriately.
Then just desaturate all the area's that need to be desaturated.

My iphone 4S camera always comes up on Black and white how do I change this to color

Mask gradiant black and white no matter what color is chosen

My mask gradiant is black and white not matter what color I choose. How do I fix that?

You may wonder about that from now on until:
1. When someone expresses difficulty understanding you, describe just what you mean, using different terms.
2. Use whole paragraphs. Maybe even more than one. This isn't instant messaging.
Your phrase "mask gradiant" (assuming one reads through the misspelling) could mean many things. You haven't provided enough context to know what you really mean.
If I put a gradient into a mask it may be because I want the image on a layer to fade away, revealing what's underneath. The gradient can only be grayscale (black, gray, or white) - it cannot be colored.
I can't imagine why you would want to color a mask. It makes no sense. What are you really trying to accomplish? Did someone tell you that you could do this?
Perhaps you're using the terms "mask" or "gradient" incorrectly, or for something that is really called something else.
Help us help you out here.

Yeah it's dead. Take it to an Apple Genius Bar and have it checked out. Then buy a new one.

My black and white pictures show up colored

My photos aren't the same as the filter I used in the camera when I was taking the picture, for example my black and white photos show up colored.

Have you checked your ink levels and the inkjet jets for plugging?

While I'm using facebook in my iPad with Safari browser,sometimes it will just switch to main menue.It also happened with the Facebook apps from the apple store. And the color of the bookmark area becomes black instead of a normal grey color.

While I'm using facebook in my iPad with Safari browser,sometimes it will just switch to main menue.It also happened with the Facebook apps from the apple store. And the color of the bookmark area becomes black instead of a normal grey color.

Then if you have tried all the browsers try connecting the system to yoour router with an Ethernet cable and turn WiFi off. If you have the same problem then it more then likely after your computer, Router or modem or connection from your ISP.
If you get good browsing with the Ethernet cable then it is either the WiFi card in your Mac or the WiFi system in your router.

There was a popup on my iPhone 5 and all screens are now black and white. How do I reset it to color?

A Popup appeared on my iPhone 5 screen and I thought I clicked for better visibility in color, however all screen are black and white. How do I get color back on screens? I have gone to settings, general, accessibility and tried numerous options there to no avail.

I would suggest checking Grayscale, and also Contrast in Settings > General > Accessibility. If changing those options doesn't make a difference, you could always go to Settings > General > Reset > Reset All Settings.

When I open CR2 RAW files from Powershot G10 they are in black and white. How do I get colour

I'm using Elements 13 on a PC running Windows 8.1. Each time I open a CR2 RAW file from a Canon Powershot G10 it displays in black and white. The image transferred to Elements is still in black and white. Why can I not see the image in colour?

Try holding down your Alt or Option key. The Cancel button in the Raw dialog will change to Reset.
Click on that Reset, and hopefully it goes back to defaults.

Help! My photographs are turning black and white!

I edit and save a photograph in color. I then apply a black and white action to it and save it as a different file name. Somehow, when I look back in the folder it's changed the color version of the photograph to Black and white. Please please please help!!!

We can't know anything. You are not providing any system information, what program and version you use, what image files, how you run the actions and so on. In any case, ask in whatever product forum and provide more details - a lot more.
