reg_Map
import { reg_Map } from '@banou/opencv-wasm'Use after await initOpenCV(). See the initialization and named imports guide.
Native object: release it with using or delete(). Factories can return null; check before calling methods.
Base class for modelling a Map between two images.
The class is only used to define the common interface for any possible map.
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;The this result.
warp
Warps image to a new coordinate frame. The calculation is img2(x)=img1(T^{-1}(x)), as we have to apply the inverse transformation to the points to move them to were the values of img2 are.
warp(img1: Mat, img2: Mat): void;img1Original image
img2Output destination, filled by the native operation. Warped image
inverseWarp
Warps image to a new coordinate frame. The calculation is img2(x)=img1(T(x)), so in fact this is the inverse warping as we are taking the value of img1 with the forward transformation of the points.
inverseWarp(img1: Mat, img2: Mat): void;img1Original image
img2Output destination, filled by the native operation. Warped image
inverseMap
Calculates the inverse map
inverseMap(): reg_Map | null;Inverse map
compose
Changes the map composing the current transformation with the one provided in the call. The order is first the current transformation, then the input argument.
compose(map: reg_Map | null): void;mapTransformation to compose with.
scale
Scales the map by a given factor as if the coordinates system is expanded/compressed by that factor.
scale(factor: number): void;factorExpansion if bigger than one, compression if smaller than one
