createCLAHE

Image processingfunctionOpenCV 5.0.0

import { createCLAHE } from '@banou/opencv-wasm'

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

Explore visually: CLAHE local contrast →

Equalize local histograms while limiting how much a concentrated bin can amplify contrast.

VISUAL WALKTHROUGHColour

REFERENCE INPUTLow-contrast image

The same scene stays here while the working view changes.

→

RESULTInterpolate local mappings

Four neighbouring tile mappings blend bilinearly. Contrast grows locally without hard tile seams.

Computed teaching example on a 24 × 16 image. Small kernels and simplified settings keep each change visible; use the image laboratory for native OpenCV.

Creates a smart pointer to a cv::CLAHE class and initializes it.

createCLAHE(clipLimit: number, tileGridSize: Size): CLAHE | null;

3 available overloads

createCLAHE(): CLAHE | null;

createCLAHE(clipLimit: number): CLAHE | null;

createCLAHE(clipLimit: number, tileGridSize: Size): CLAHE | null;

clipLimit

Threshold for contrast limiting.

tileGridSize

Size of grid for histogram equalization. Input image will be divided into equally sized rectangular tiles. tileGridSize defines the number of tiles in row and column.

Returns

The CLAHE | null result.
