img_hash_colorMomentHash

img_hashfunctionOpenCV 5.0.0
import { img_hash_colorMomentHash } from '@banou/opencv-wasm'

Use after await initOpenCV(). See the initialization and named imports guide.

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

Computes color moment hash of the input, the algorithm is come from the paper "Perceptual Hashing for Color Images Using Invariant Moments"

img_hash_colorMomentHash(inputArr: Mat, outputArr: Mat): void;
inputArr

input image want to compute hash value, type should be CV_8UC4, CV_8UC3 or CV_8UC1.

outputArr

Output destination, filled by the native operation. 42 hash values with type CV_64F(double)
