Applies the joint bilateral filter to an image

dst = cv.jointBilateralFilter(src, joint)
dst = cv.jointBilateralFilter(src, joint, 'OptionName',optionValue, ...)

Input

• src Source 8-bit or floating-point, 1-channel or 3-channel image with the same depth as joint image.
• joint Joint 8-bit or floating-point, 1-channel or 3-channel image.

Output

• dst Destination image of the same size and type as src.

Options

• Diameter Diameter of each pixel neighborhood that is used during filtering. If it is non-positive, it is computed from SigmaSpace. default -1
• 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. default 25.0
• 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 Diameter>0, it specifies the neighborhood size regardless of SigmaSpace. Otherwise, Diameter is proportional to SigmaSpace. default 10.0
• BorderType Border mode used to extrapolate pixels outside of the image. See cv.copyMakeBorder. default 'Default'

Note that cv.bilateralFilter and cv.jointBilateralFilter use L1 norm to compute difference between colors.
