[mmsupcanon] [Up] [mmcthick] | Sup-generating And Inf-generating |
mmsupgen creates the binary image
y
by computing the transformation of the image
f
by the sup-generating operator characterized by the interval
Iab
. The sup-generating operator is just a relaxed template matching, where the criterion to keep a shape is that it be inside the interval
Iab
. Note that we have the classical template matching when
a=b
. Note yet that the sup-generating operator is equivalent to the classical hit-miss operator.
>>> f=mmbinary([ [0,0,1,0,0,1,1], [0,1,0,0,1,0,0], [0,0,0,1,1,0,0]])
>>> i=mmendpoints()
>>> print mmintershow(i)
. . . 0 1 0 0 0 0
>>> g=mmsupgen(f,i)
>>> print g
[[0 0 0 0 0 0 0] [0 1 0 0 0 0 0] [0 0 0 0 0 0 0]]
