RollingGuidanceFilter(InputArray, OutputArray, int, double, double, int, BorderTypes)

Applies the rolling guidance filter to an image.

public static void RollingGuidanceFilter(InputArray src, OutputArray dst, int d = -1, double sigmaColor = 25, double sigmaSpace = 3, int numOfIter = 4, BorderTypes borderType = BorderTypes.Default)

Parameters

src InputArray

8-bit or floating-point, 1-channel or 3-channel image.

dst OutputArray

Destination image of the same size and type as src.

d int

Diameter of each pixel neighborhood that is used during filtering. If it is non-positive, it is computed from sigmaSpace.

sigmaColor double

Filter sigma in the color space. A larger value of the parameter means that farther colors within the pixel neighborhood(see sigmaSpace) will be mixed together, resulting in larger areas of semi-equal color.

sigmaSpace double

Filter sigma in the coordinate space. A larger value of the parameter means that farther pixels will influence each other as long as their colors are close enough(see sigmaColor). When d>0 , it specifies the neighborhood size regardless of sigmaSpace.Otherwise, d is proportional to sigmaSpace.

numOfIter int

Number of iterations of joint edge-preserving filtering applied on the source image.
