mmbinary converts a gray-scale image
f
into a binary image
y
by a threshold rule. A pixel in
y
has the value 1 if and only if the corresponding pixel in
f
has a value greater or equal
k1
.
def mmbinary(f, k1=1): from Numeric import array if type(f) is not array: f = array(f) y = array(f>=k1).astype('1') return y
