RETURN TYPEvoid

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

Filtering is the fundamental operation in image and video processing. Edge-preserving smoothing filters are used in many different applications [EM11] .

edgePreservingFilter(src: Mat, dst: Mat, flags: number, sigma_s: number, sigma_r: number): void;

4 available overloads

edgePreservingFilter(src: Mat, dst: Mat): void;

src

Input 8-bit 3-channel image.

dst

Output destination, filled by the native operation. Output 8-bit 3-channel image.

flags

sigma_s

%Range between 0 to 200.

sigma_r

%Range between 0 to 1.
