mediaLib Library Functions mlib_ImageErode4(3MLIB)
NAME
mlib_ImageErode4 - four neighbor erode
SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ]
#include
mlib_status mlib_ImageErode4(mlib_image *dst, const mlib_image *src);
DESCRIPTION
The mlib_ImageErode4() function performs an erode operation
on an image by using each pixel's four orthogonal neighbors.The source and destination images must be single-channel
images. The data type can be MLIB_BIT, MLIB_SHORT,
MLIB_USHORT, or MLIB_INT.
For 4-neighbor binary images, it uses the following equa-
tion: dst[x][y][0] = AND{ src[x][y][0],src[x-1][y][0], src[x+1][y][0],
src[x][y-1][0], src[x][y+1][0] }
For 4-neighbor grayscale images, it uses the following equa-
tion: dst[x][y][0] = MIN{ src[x][y][0],src[x-1][y][0], src[x+1][y][0],
src[x][y-1][0], src[x][y+1][0] }
where x = 1, ..., w-2; y = 1, ..., h-2.
PARAMETERS
The function takes the following arguments: dst Pointer to destination image. src Pointer to source image.RETURN VALUES
The function returns MLIB_SUCCESS if successful. Otherwise
it returns MLIB_FAILURE.
