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.

example: modules/shape/samples/shape_example.cpp An example using shape distance algorithm Abstract base class for shape distance algorithms.

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.

computeDistance

Compute the shape distance between two shapes defined by its contours.

computeDistance(contour1: Mat, contour2: Mat): number;

contour1

Contour defining first shape.

contour2

Contour defining second shape.

Returns

The number result.
