cv.BackgroundSubtractorMOG() doesn't work on opencv.js
Hello guys.I want to use BackgroundSubtractorMOG() on my opencv .js project but cv.BackgroundSubtractorMOG() doesn't work on my javascript code.I get following error:
BindingError: BackgroundSubtractor has no accessible constructor
My Code:
let video = document.getElementById('videoInput');
let cap = new cv.VideoCapture(video);
let frame = new cv.Mat(video.height, video.width, cv.CV_8UC4);
let fgmask = new cv.Mat(video.height, video.width, cv.CV_8UC1);
let fgbg = new cv.BackgroundSubtractorMOG(500, 16, true);
const FPS = 30;
function processVideo() {
try {
if (!streaming) {
// clean and stop.
frame.delete(); fgmask.delete(); fgbg.delete();
return;
}
let begin = Date.now();
// start processing.
cap.read(frame);
fgbg.apply(frame, fgmask);
frame.copyTo(fgmask, fgmask)
let M = cv.Mat.eye(3, 3, cv.CV_32FC1);
let anchor = new cv.Point(-1, -1);
cv.filter2D(fgmask, fgmask, cv.CV_8U, M, anchor, 0, cv.BORDER_DEFAULT);
cv.imshow('canvasOutput', fgmask);
// schedule the next one.
let delay = 1000/FPS - (Date.now() - begin);
setTimeout(processVideo, delay);
} catch (err) {
utils.printError(err);
}
};
// schedule the first one.
setTimeout(processVideo, 0);
