Applying new pixel intensity values to the original image?

Asked by vivek govind
on 23 Mar 2013

The purpose of my program was to read an image , apply an algorithm which calculates the new pixel values and then create a result image that has the newly mapped pixel values , with pixels having values >255 or <0 being clipped from the image.

My problem is that i have obtained an array with stores all the newly generated pixel values , i ned to apply these values over the original image in order to enhance the older image . how do i do that?

If the array has the newly generated pixel values, then it is the enhanced image.

Or is that array a vector of values indicating the new pixel value that each unique old value should be translated to? If so then index that vector at (one plus the old matrix)
