NAME

mlib_ImageMedianFilter7x7_US - 7x7 median filter, unsigned  

SYNOPSIS

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

mlib_status mlib_ImageMedianFilter7x7_US(mlib_image *dst,
    const mlib_image *src, mlib_median_mask mmask, mlib_s32 cmask,
    mlib_edge edge, mlib_s32 bits);

 

DESCRIPTION

The mlib_ImageMedianFilter7x7_US() function performs median filtering on an MLIB_SHORT type of image that contains unsigned data. 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

bits

The number of unsigned bits for pixel dynamic range. 9 ≤ bits ≤ 15.

 

RETURN VALUES

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