BilateralFilter

Apply a Bilateral filter to smooth the image but preserve edges.
Can use available TwinCAT Job Tasks for executing parallel code regions.

Syntax

Definition:

HRESULT BilateralFilter(
    HRESULT                        hrPrev,
    ITcVnImage*                    ipSrcImage,
    ITcVnImage*&                   ipDestImage,
    LONG                           nDiameter,
    double                         fSigmaColor,
    double                         fSigmaSpace,
    ETcVnBorderInterpolationMethod eBorderType = BIM_DEFAULT
)

Parameters

Name	Type	Default	Description
hrPrev	HRESULT		HRESULT indicating the result of previous operations (If SUCCEEDED(hrPrev) equals false, no operation is executed.)
ipSrcImage	ITcVnImage*		Source image
ipDestImage	ITcVnImage*&		Destination image (Must be different from ipSrcImage! An appropriate destination image will be created if required.)
nDiameter	LONG		Diameter of the pixel neighborhood used for filtering (e.g. 5, 7, 9). If <= 0, it is automatically chosen dependend on fSigmaSpace.
fSigmaColor	double		Sigma used for color space filtering (> 0). A larger value means that farther colors are mixed together.
fSigmaSpace	double		Sigma used for coordinate space filtering (> 0). A larger value means that farther pixels can influence each other.
eBorderType	ETcVnBorderInterpolationMethod	BIM_DEFAULT	Image border handling

Return value
