[mmcthick] [Up] [mmcwatershed] | Thinning And Thickening |
Implemented in Python.
y | Image Binary image. |
mmcthin creates the binary image
y
by performing a thinning of the binary image
f
conditioned to the binary image
g
. The number of iterations of the conditional thinning is
n
and in each iteration the thinning is characterized by rotations of
theta
of the interval
Iab
.
def mmcthin(f, g, Iab=None, n=-1, theta=45, DIRECTION="CLOCKWISE"): from Numeric import product from string import upper if Iab is None: Iab = mmhomothin() DIRECTION = upper(DIRECTION) assert mmisbinary(f),'f must be binary image' if n == -1: n = product(f.shape) y = f old = y for i in range(n): for t in range(0,360,theta): sup = mmsupgen( y, mminterot(Iab, t, DIRECTION)) y = mmunion(mmsubm( y, sup),g) if mmisequal(old,y): break old = y return y
mmfreedom | Control automatic data type conversion. |
mmthin | Image transformation by thinning. |
mmendpoints | Interval to detect end-points. |
mmhomothin | Interval for homotopic thinning. |
mmse2hmt | Create a Hit-or-Miss Template (or interval) from a pair of structuring elements. |
