mediaLib Library Functions       mlib_ImageMedianFilterMxN(3MLIB)



NAME
     mlib_ImageMedianFilterMxN - MxN median filter

SYNOPSIS
     cc [ flag... ] file... -lmlib [ library... ]
     #include 

     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  fil-
              tered.  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  fol-
              lowing:
