Median Filter. 
A median filter is similar to the arbitrary filter except that instead of a weighted sum, the median value of the pixels covered by the kernel is returned. 
C Interface for median filter. 
- Parameters
- 
  
    | [out] | out | array is the processed image |  | [in] | in | array is the input image |  | [in] | wind_length | is the kernel height |  | [in] | wind_width | is the kernel width |  | [in] | edge_pad | value will decide what happens to border when running filter in their neighborhood. It takes one of the values [AF_PAD_ZERO | AF_PAD_SYM] |  
 
- Returns
- AF_SUCCESS if the median filter is applied successfully, otherwise an appropriate error code is returned.
