I think you want to cast 'new_image' and 'original_image' there,
not 'size'!
Also, it would be safer to declare the parameters directly as
being of type Py_ssize_t instead of going through int, just in
case int is not big enough.
def fitness(Py_ssize_t new_image, Py_ssize_t original_image, Py_ssize_t
size):
cdef unsigned char *new_pixels = <unsigned char*>new_image
cdef unsigned char *original_pixels = <unsigned char*>original_image
