Hello, I am working on automatically adjusting the threshold for an image. How do I select a particular percentage of the peak of the histogram for thresholding without actually plotting the values. The image below was plotted using histogram(Image).

Sounds like you need the histcounts command.

The histcounts command
N = histcounts(X);
outputs the bin counts, without plotting them.
You could find the maximum value of this
maxN = max(N);
and then set your threshold as some percentage of this maximum value.
