NAME

mlib_ImageErode4_Fp - four neighbor erode  

SYNOPSIS

cc [ flag... ] file... -lmlib [ library... ]
#include <mlib.h>

mlib_status mlib_ImageErode4_Fp(mlib_image *dst, const mlib_image *src);

 

DESCRIPTION

The mlib_ImageErode4_Fp() 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 of the images can be MLIB_FLOAT or MLIB_DOUBLE.

For 4-neighbor grayscale images, it uses the following equation:

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.
