RETURN TYPEOwned native handle

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

Native object: release it with using or delete(). Factories can return null; check before calling methods. Inherits Algorithm.

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.

calc

Calculates an optical flow.

calc(I0: Mat, I1: Mat, flow: Mat): void;

I0

first 8-bit single-channel input image.

I1

second input image of the same size and the same type as prev.

flow

Input/output value, modified by the native operation. computed flow image that has the same size as prev and type CV_32FC2.

collectGarbage

Releases all inner buffers.

collectGarbage(): void;
