Yes. To change the counts array, just change it. For example to change the number of counts in bin #101 (which holds counts for gray level 100), and to get rid of big spikes at the ends, do this:
[pixelCounts, grayLevels] = imhist(grayImage);
pixelCounts(101) = 1234; % Change count to 1234.
% Suppress big spikes at 0 and 255:
pixelCounts(1) = 0;
pixelCounts(256) = 0;

Image Analyst actually i have made changes in the histogram of an image, and want to know that how much distortion is introduced into the image, for that i have to generate the image back from the histogram. is there any way to do that?
