Solution: Object Tracker

Explore how to build an object tracker in OpenCV by reading video frames and selecting objects to track. Understand how to initialize the TrackerMOSSE, update tracking in real time, and display results, enabling you to apply practical video analysis in C++.

In this object tracker, we draw a tracking box around an object in the first frame of the video, and then that box will track the object. Let’s look at the code and try to understand it.

Read the video

First, we use the following code to read the video.

// Reads the video frame by frame
vid.read(frame);

We read the videos by getting each frame of the video as an image using VideoCapture() and continuously looping through it.

// Capturs the video
cv::VideoCapture vid("/usercode/object_detection_vid.mp4");

Draw a tracking box

The Mat object frame is ...
