#include <mlib.h>

mlib_status mlib_ImageRankFilterMxN_Fp(mlib_image *dst,
     const mlib_image *src, mlib_s32 m, mlib_s32 n, mlib_s32 rank);

Description

The mlib_ImageRankFilterMxN_Fp() function performs floating-point 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.

Parameters

The function takes the following arguments:

dst

Pointer to destination image.

src

Pointer to source image.

m

Width of the filter window. m must be odd number greater than 1.

n

Height of the filter window. n must be odd number greater than 1.

rank

The rank of the destination pixel. The pixel with minimum value is designated rank 0.

Return Values

The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
