import { GeneralizedHoughBallard } 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 GeneralizedHough.
finds arbitrary template in the grayscale image using Generalized Hough Transform
Detects position only without translation and rotation [Ballard1981] .
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.
setLevels
R-Table levels.
setLevels(levels: number): void;levelslevels argument (number).
getLevels
Read the levels.
R-Table levels.
getLevels(): number;The number result.
setVotesThreshold
The accumulator threshold for the template centers at the detection stage. The smaller it is, the more false positions may be detected.
setVotesThreshold(votesThreshold: number): void;votesThresholdvotes threshold argument (number).
getVotesThreshold
Read the votes threshold.
The accumulator threshold for the template centers at the detection stage. The smaller it is, the more false positions may be detected.
getVotesThreshold(): number;The number result.
