Revision history [back]

Hello,

I wanted to load any of these tracking algorithms in javascript using opencvjs. please suggest me or giving some links to do the same. (We do have opencv.js compiled file and it has all these tracking algortihms)

I tried to refer this c++ and Python code link :

https://www.learnopencv.com/object-tracking-using-opencv-cpp-python/#opencv-tracking-api

But getting error when initialized with below code

code:

let video = document.getElementById('videoInput'); let cap = new cv.VideoCapture(video);

// take first frame of the video
let frame = new cv.Mat(video.height, video.width, cv.CV_8UC4);
cap.read(frame);

// hardcode the initial location of window
let trackWindow = new cv.Rect(150, 60, 125, 125);

  let tracker_c = cv.TrackerKCF_create();

// set up the ROI for tracking
let roi = frame.roi(trackWindow);

Errror:

TypeError: cv.TrackerKCF_create is not a function
