Dear All,
I am a student of Masters First Year....I am working on how to segment a part of Image using histograms. I am at initial stage of this part.
I need help in this regard, as i am converting an image in histogram i.e. f=imread('any image.jpg'); g=rgb2gray(f); h=imhist(g) figure, imshow(h) as i m executing this code i am not getting any histogram of the image...can anybody tell me why?

To see the histogram, use imhist without any return argument.
In
h = imhist(g);
h is not an image, nor a handle to a plot, it is a vector of the counts of the bins. h would be better named as count or anything else more meaningful. As per the documention of imhist, the way to plot the histogram if you want to acquire the bin count is with:
[counts, binlocations] = imhist(g); %and again use meaningful variable name for your image
figure, stem(binlocations, counts);
