How to use Edge Histogram Descriptor (EHD) to compare 2 Image?

3 views (last 30 days)
My problem is I do not know how to write EHD code to compare 2 image. Please help me, thanks
z = clock;
I = imread('a.jpg');
I = rgb2gray(I);
EHD
h = imhist(I); % this will have default bins 256
J = imread('b.jpg');
J = rgb2gray(J);
EHD
h1 = imhist(J); % this will have default bins 256
E_distance = sqrt(sum((h-h1).^2));
E_distance
etime(clock,z)

I don't know that algorithm though what you did doesn't sound or look right. The histogram doesn't have any information on whether or not there are edges in an image.
