haar-detect

The module exposes a single function createDetector which accepts a classifier and options and returns a function that will perform the detection.

import { createDetector } from "haar-detect";
import classifier from "haar!./my-trained-cascade.xml";
 
const detect = createDetector(classifier, { width: 640, height: 480, scale: 1.2 });
 
const img = document.images[0];
 
const rectangles = detect(img);
 

classifiers

This module doesn't ship with any classifiers, but instead you could use the modules from mtschirs/js-objectdetect or with the haar-loader you can use any XML classifier, such as the banana classifier from coding-robin.de or those that are part of the OpenCV project at alereimondo.no-ip.org.
