text_TextDetector

textclassOpenCV 5.0.0
import { text_TextDetector } from '@banou/opencv-wasm'

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

ARGUMENTSConstructor or factory
CLASStext_TextDetector
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.

An abstract class providing interface for text detection algorithms

Upstream declaration ↗

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.

detect

Method that provides a quick and simple interface to detect text inside an image

detect(inputImage: Mat, Bbox: RectVector, confidence: FloatVector): void;
inputImage

an image to process

Bbox

Output destination, filled by the native operation. a vector of Rect that will store the detected word bounding box

confidence

Output destination, filled by the native operation. a vector of float that will be updated with the confidence the classifier has for the selected bounding box
