cc [ flag... ] file... –lmlib [ library... ] #include <mlib.h> mlib_status mlib_ImageRankFilterMxN(mlib_image *dst, const mlib_image *src, mlib_s32 m, mlib_s32 n, mlib_s32 rank);
The mlib_ImageRankFilterMxN() function performs MxN rank filtering on an image. Each pixel of the destination image is the pixel with the user-specified rank in the filter window.
The source and destination images must be single-channel images.
The function takes the following arguments:
Pointer to destination image.
Pointer to source image.
Width of the filter window. m must be odd number greater than 1.
Height of the filter window. n must be odd number greater than 1.
The rank of the destination pixel. The pixel with minimum value is designated rank 0.
The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
