[mmThick] [Up] [mmWatershed] Thinning And Thickening

mmThin
Image transformation by thinning.

Synopsis

Image mmThin ( const Image& f , const Interval& Iab = NullInterval, const Double& n = -1, const Double& theta = 45, const String& DIRECTION = "CLOCKWISE" );

Input

f Image [ Binary image ]

Iab Interval

Default: NullInterval (mmhomothin)
n Double [ Non-negative integer. ]

Number of iterations.

Default: -1
theta Double

Degrees of rotation: 45, 90, or 180.

Default: 45
DIRECTION String

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

Default: "CLOCKWISE"

Output

y Image [ Binary image ]

Description

mmThin creates the binary image y by performing a thinning of the binary image f. The number of iterations of the thinning is n and each iteration is performed by subtracting the points that are detect in f by hit-miss operators characterized by rotations of theta of the interval Iab. When n is infinite and the interval is mmHomothin (default conditions), mmThin gives the skeleton by thinning.
