Name

mlib_ImageMedianFilter7x7 - 7x7 median filter

Synopsis

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

mlib_status mlib_ImageMedianFilter7x7(mlib_image *dst,
     const mlib_image *src, mlib_median_mask mmask, mlib_s32 cmask,
     mlib_edge edge);

Description

The mlib_ImageMedianFilter7x7() function performs 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.

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 corresponded 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.
