NAME
mlib_ImageMedianFilterMxN - MxN median filter
SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ]
#include <mlib.h>
mlib_status mlib_ImageMedianFilterMxN(mlib_image *dst,
const mlib_image *src, mlib_s32 m, mlib_s32 n, mlib_median_mask mmask,
mlib_s32 cmask, mlib_edge edge);
DESCRIPTION
The mlib_ImageMedianFilterMxN() function performs MxN median filtering on an image. Each pixel of the destination image is the pixel with
rank middle in the filter window.
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.
mmask Shape of the mask to be used for median filtering. It can be one of the following:
MLIB_MEDIAN_MASK_RECT
MLIB_MEDIAN_MASK_PLUS
MLIB_MEDIAN_MASK_X
MLIB_MEDIAN_MASK_RECT_SEPARABLE
cmask Channel mask to indicate the channels to be filtered. Each bit of which represents a channel in the image. The channels corre-
sponded to 1 bits are those to be processed.
edge Type of edge condition. It can be one of the following:
MLIB_EDGE_DST_NO_WRITE
MLIB_EDGE_DST_FILL_ZERO
MLIB_EDGE_DST_COPY_SRC
MLIB_EDGE_SRC_EXTEND
RETURN VALUES
The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
