ppu-ocv/operations/grayscale.d.ts

A type-safe, modular, chainable image processing library built on top of OpenCV.js with a fluent API leveraging pipeline processing.

import { cv } from "../cv-provider.js";
/** Options for the grayscale conversion operation (no configurable fields). */
export type GrayscaleOptions = PartialOptions;
/** Convert the image to grayscale using `COLOR_RGBA2GRAY`. */
export declare function grayscale(img: cv.Mat, _options: GrayscaleOptions): OperationResult;
