GeneralizedHoughBallard

Image processingclassOpenCV 5.0.0
import { GeneralizedHoughBallard } from '@banou/opencv-wasm'

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

ARGUMENTSConstructor or factory
CLASSGeneralizedHoughBallard
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 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;
Returns

The this result.

setLevels

R-Table levels.

setLevels(levels: number): void;
levels

levels argument (number).

getLevels

Read the levels.

R-Table levels.

getLevels(): number;
Returns

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;
votesThreshold

votes 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;
Returns

The number result.
