#include "ltwrappr.h"

virtual L_INT LBitmap::MeanShift(uRadius, uColorDistance ,uFlags = 0)

L_UINT uRadius;	/* size of kernel */
L_UINT uColorDistance;	/* color difference */
L_UINT uFlags;	/* flag */

Performs noise reduction while preserving detail.

Parameter	Description
uRadius	Size of the kernel where the middle pixel would be considered as the source pixel.
uColorDistance	Color difference between the investigated pixel and the source pixel.
uFlags	Reserved for future use. Must be 0.

Returns

SUCCESS	The function was successful.
< 1	An error occurred. Refer to Return Codes.

Comments

To keep details while removing noise, pass low positive values to ColorDistance parameter.
