[mmIntersec] [Up] [mmSymdif] Operations

mmSubm
Subtraction of two images, with saturation.

Synopsis

Image mmSubm ( const Image& f1 , const Image& f2 );

Input

f1 Image [ Unsigned gray-scale (uint8 or uint16), signed (int32) or binary image ]

f2 Image [ Unsigned gray-scale (uint8 or uint16), signed (int32) or binary image ]

Or constant.

Output

y Image [ Unsigned gray-scale (uint8 or uint16), signed (int32) or binary image ]

Description

mmSubm creates the image y by pixelwise subtraction of the image f2 from the image f1. When the subtraction of the values of two pixels is negative, 0 is taken as the result of the subtraction. When f1 and f2 are binary images, y represents the set subtraction of f2 from f1.
