Constructors and members

clone

Create another handle to the same native object. This retains the object without copying its pixels or algorithm state; dispose both handles separately.

clone(): this;

Returns

The this result.

filter

Produce domain transform filtering operation on source image.

filter(src: Mat, dst: Mat, dDepth: number): void;

2 available overloads

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

filter(src: Mat, dst: Mat, dDepth: number): void;

src: filtering image with unsigned 8-bit or floating-point 32-bit depth and up to 4 channels.
dst: Output destination, filled by the native operation. destination image.
dDepth: optional depth of the output image. dDepth can be set to -1, which will be equivalent to src.depth().
