MATLAB: Drawing the gradient histogram of a grey image’s one

differential equationshistogramMATLAB

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.

Look at the values you get from the gradient image when you call imgradient().

[pixelCounts, grayLevels] = imhist(grayImage);
[maxCount, indexOfMax] = max(pixelCounts);
grayLevelAtMax = grayLevels(indexOfMax);
