cc [ flag... ] file... –lmlib [ library... ] #include <mlib.h> mlib_status mlib_ImageMinFilter5x5_Fp(mlib_image *dst, const mlib_image *src);
The mlib_ImageMinFilter5x5_Fp() function replaces the center pixel in a neighborhood with the floating-point minimum value in that neighborhood for each 5x5 neighborhood in the image.
The source and destination images must be single-channel images.
It uses the following equation:
dst[x][y][0] = MIN{ src[p][q][0], x-2 ≤ p ≤ x+2; y-2 ≤ q ≤ y+2 }
where x = 2, ..., w - 3; y = 2, ..., h - 3.
The function takes the following arguments:
Pointer to destination image.
Pointer to source image.
The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
