Hi folks,

I'm trying to plot the differential/gradient of a gray image's histogram, to highlight the points of interest more readily.

Searching for a function that does this hasn't yielded anything, but I'm unsure how to go about this in Matlab.

Is there a tutorial or something similar you can point me towards please?

Thanks in advance

See imgradient(): https://www.mathworks.com/help/images/ref/imgradient.html. Can you further clarify your question about the histogram.

If you want you can use kmeans() to partition the histogram into sections. Personally I don't think it does a very good job but it will find the peak regions.
