Edge-Detection-Wasm

This is a simple rust library that is compiled down to WebAssembly using wasm-pack. The exported function (detect) takes in a pixel buffer in the form of a ClampedUint8Array and outputs a new pixel buffer that has all the detected "edges" in that image highlighted with a given color

Alot of this code was inspired by https://github.com/PistonDevelopers/imageproc

🚴 Usage

import * as wasm from 'edge-detection-wasm';
 
const canvas = document.getElementById('canvas');
const ctx = canvas.getContext('2d');
 
const imageData = ctx.getImageData(0, 0, canvas.width, canvas.height);
const data = wasm.detect(imageData.data, canvas.width, canvas.height, 0xFFFFFFFF);
ctx.putImageData(new ImageData(data, canvas.width, canvas.height), 0, 0);

🏎 Speed

On my newish MBP, the detect function completes in about 25ms. I'd like to get it under 20ms.
