Remove dark portion from Image

[Gak]

Hi,

I have just started working with NI VISION. I have attached one image with this post.

Can some one tell me how I can remove dark part in image? I read about histogram, which gives total number of pixels at each grayscale level.

But I don't know how I can use this information to improve image quality or in my case how I can use it to equalize the pixel values encircled with rest of the image.

I hope I have explained my problem properly.

Hi,

What kind of camera do you have? FireWire, GigE, CameraLink?

If it's a CameraLink one, you could take a look at the example VI : C:\Program Files\National Instruments\LabVIEW 2010\examples\IMAQ\IMAQ Color.llb\Color Processing.vi

I found the solution of the problem. I used "Pixel Manipulation".

If anyone has any better ideas then please share.

Probably not a "better" idea, but mybe a source of idea, here's an example to manipulate color planes of an RGB image. It's very basic, it lets you amplify of reduce a color plane by multiplying it by a number between 0 and 2.
