I want to improve my foreground extraction on my opencv.js project.I am extracting moving foreground from static background.My output foreground have gaps and little bit noisy. How can i fill this gaps with original foreground object color?

Here is 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.BackgroundSubtractorMOG2(500, 16, false);
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)
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);
