Show in webframe

#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.

This function supports 12 and 16-bit grayscale and 48 and 64-bit color images. Support for 12 and 16-bit grayscale and 48 and 64-bit color images is available in the Document and Medical Imaging toolkits.

This function does not support 32-bit grayscale images. It returns the error code ERROR_GRAY32_UNSUPPORTED if a 32-bit grayscale image is passed to this function.
