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 reg_Mapper.

Gradient mapper for a projective transformation

Upstream declaration ↗

Constructors and members

static new

Create an owned reg_MapperGradProj object. Release native handles with using or delete().

new(): reg_MapperGradProj;

Returns

The reg_MapperGradProj result.

Upstream declaration ↗

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.

calculate

Calculate mapping between two images

calculate(img1: Mat, img2: Mat, init: reg_Map | null): reg_Map | null;

2 available overloads

calculate(img1: Mat, img2: Mat): reg_Map | null;

calculate(img1: Mat, img2: Mat, init: reg_Map | null): reg_Map | null;

img1

Reference image

img2

Warped image

init

init argument (reg_Map | null).

Returns

Map from img1 to img2, stored in a smart pointer.

Upstream declaration ↗

getMap

Returns a map compatible with the Mapper class

getMap(): reg_Map | null;

Returns

Pointer to identity Map
