HistogramCostExtractor
import { HistogramCostExtractor } 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. Inherits Algorithm.
Abstract base class for histogram cost 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;The this result.
buildCostMatrix
Compute pairwise histogram matching costs from the two descriptor sets and fill the supplied cost matrix.
buildCostMatrix(descriptors1: Mat, descriptors2: Mat, costMatrix: Mat): void;descriptors1descriptors1 argument (Mat).
descriptors2descriptors2 argument (Mat).
costMatrixOutput destination, filled by the native operation. cost matrix argument (Mat).
setNDummies
Set the ndummies used by this HistogramCostExtractor object.
setNDummies(nDummies: number): void;nDummiesn dummies argument (number).
getNDummies
Return the ndummies configured on this HistogramCostExtractor object.
getNDummies(): number;The number result.
setDefaultCost
Set the default cost used by this HistogramCostExtractor object.
setDefaultCost(defaultCost: number): void;defaultCostdefault cost argument (number).
getDefaultCost
Return the default cost configured on this HistogramCostExtractor object.
getDefaultCost(): number;The number result.
