Changes necessary to make it work in Python 2.7 #1
Just FYI: in order to make the example run correctly in Python 2.7 there are two changes necessary to deal with the different handling of integer division:
vals = np.eye(win_size) - (1/win_size)*(1 + np.einsum('...ij,...kj->...ik',X , winI - win_mu))
needs to be changed to
vals = np.eye(win_size) - (1.0/win_size)*(1.0 + np.einsum('...ij,...kj->...ik',X , winI - win_mu))
and
L = computeLaplacian(img/255)
becomes
L = computeLaplacian(img/255.0)
