MATLAB: Hamming distance between two binary matrices

image processing

How can I calculate the hamming distance between 2 20×20 binary matrices?

Thank you in advance.

D = pdist2(X,Y,'hamming')

Use euclidean distance

d = sqrt( (x2-x1).^2 + (y2-y1).^2 );

hamming is not for hamming distance I guess. What is the type of input you want to compute the hamming distance.

Hamming distance is usually calculated between character array or binary array. For binary array it is very simple and straight forward.

For binary array sum of absolute difference can give you hamming distance.

For example.

a = [1 0 0 1];
b = [1 1 1 1];
h_d = sum(abs(a-b));
