Don't post the same question multiple times every time you want to add some information. Posting multiple times will not get you a faster or better answer.

Like we said in your duplicate question from last month, use findpeaks() in the Signal Processing Toolbox
[peakValues, peakIndexes] = findpeaks(counts);
[~, valleyIndexes] = findpeaks(-counts);
valleyValues = counts(valleyIndexes);
just do that for each histogram from each color channel.
