Using "imhist" function in Matlab to plot multiple histograms on the same figure
figure, histogram, image-processing, matlab, multiple-tables
Solution
If you want both on the same axes and you don't mind loosing the lower bar, try this (I don't have the Image Toolbox right now, so I haven't tested it):
a=imread('image1.jpg')
agray=rgb2gray(a)
b=imread('image2.jpg')
bgray=rgb2gray(b)
[counts,x] = imhist(agray)
stem(counts,x,'b')
hold on
[counts,x] = imhist(bgray)
stem(counts,x,'r')
Problem
I'm new to Matlab and am trying to do a bit of image processing. I have two color images that I convert to grayscale. My goal is to be able to put the histograms for both grayscale images on the same figure so I can compare them. My code looks like this: ``` a=imread('image1.jpg') agray=rgb2gray(a) b=imread('image2.jpg') bgray=rgb2gray(b) figure,imhist(agray) figure,imhist(bgray) ``` The code works fine for looking at the two histograms independently, but I can find how to combine them into one figure for comparison. Please help!!
