[mmswatershed] [Up] [mmthin] Thinning And Thickening

mmthick
Image transformation by thickening.

Synopsis

y = mmthick ( f , Iab = NullInterval, n = -1, theta = 45, DIRECTION = "CLOCKWISE" )

Input

f Image Binary image

Iab Interval

Default: NullInterval (Interval for homotopic thickening)
n Double Non-negative integer.

Number of iterations.

Default: -1 (Infinite (denoted by -1))
theta Double

Degrees of rotation: 45, 90, or 180.

Default: 45 (45)
DIRECTION String

Direction of rotation: 'CLOCKWISE' or ' ANTI-CLOCKWISE'

Default: "CLOCKWISE" ('CLOCKWISE')

Output

y Image Binary image

Description

mmthick creates the binary image y by performing a thickening of the binary image f. The number of iterations of the thickening is n and each iteration is performed by union of f with the points that are detected in f by the hit-miss operators characterized by rotations of theta degrees of the interval Iab.
