I need to adjust the parameters of the camera like 1) brightness 2) contrast 3) Hue etc., as show in the below window.
I need to do it for Windows and Linux environments.
Can some one give me tips on where to start. On googling I could found only few open-sources. But couldnt get an idea where to start.
I have also tried with "Camera calibration With OpenCV", but still is there any other libraries available for my purpose.
well, you could try:
VideoCapture cap(0);
cap.set(CAP_PROP_SETTINGS,1);
to get to the settings dialogue

my Unity is automatically outlining my images. Do you know why and how I can turn it off? Here is how it should look like (looks like in windows fotos):
And here how it looks like in Unity. Any tips on how to remove this?
I tried Using Raw Image and normal Image but none worked.
Thanks for any help.
Texture Import Settings lets you set the texture details. In your case, I’d suggest starting with a Clamp for Wrap Mode, and Point for Filter Mode.
I got a kinect for 360 in hopes of using it in some projects regarding tracking and skeleton work, but I was stopped right on place because the kinect 360 does not have a near mode.
I'm pretty sure there's a way to force the kinect into a somewhat "near mode" by changing the default values for tracking distance, but I have no idea on where to change it or how, perhaps any of you could help me?
There is a "near mode" for Kinect v1. The according property has to be set manually tho. see here

anybody a clue?
Nvm, got it fixed. Appearantly windows used my monitor his colors so i changed those to rgba.
Different monitors display images differently. If it's just a matter of the image color quality, your monitor might not be able to handle all of the colors. If it's a matter of speed, then it's probably an issue with your computer or internet connection.
Am currently working on a new application at work and am needing some help.
Basically I need to take real time screenshots of an application running on the users desktop(not my application) then warp the image using a shade and display the wrapped screenshot at 60 frames a second.
I have a windows form application that does this but I am getting 6 frames a second and when I scale this up to 1600x1600 it drops to 2fps.
So I thought that if I could do this in xna and move as much as possible to the GPU it would speed it up.
So I have googled and googled and cant find any information on how to get a screenshot of a running application in xna other than my xna application.
Thanks for any help.
You can use XNA or additionaly the DWM or GDI+ to get the full desktop. Here are some links which can help you:
Capture screenshot of hidden desktop
Is there a way to take a screenshot of the user's Windows desktop?
C: take screenshot
What is the best way to take screenshots of a Window with C++ in Windows?
Take screen shot in XNA
I think there is no way to get a window screenshot of another application. You can use some pattern detection code to find out where a window is but I do not recommend this.
I have a slide bar to adjust the brightness of the screen on notebook displays in my application, but I found those articles from internet are adjusting the Gamma value, the behavior is not really like pressing the special key in keyboard. Is there a way to do it? Thanks in advance.
Here is some links what I found.

Very unikely that there is a way to do it with software - it's probably controlled by the laptops BIOS, which windows will not have hooks into.
If your app is for Linux you could see how the Screen Brightness applet works by looking at the code.
