RETURN TYPEvoid

Call structure. A void return can still write to destination arguments. The parameter descriptions define inputs, outputs and ownership.

Applies the rolling guidance filter to an image.

src

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

dst

Output destination, filled by the native operation. Destination image of the same size and type as src.

d

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

sigmaColor

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

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

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

borderType

Note: rollingGuidanceFilter uses jointBilateralFilter as the edge-preserving filter.
