Binder is a free service where the webcam will not work, and performance on the video will not be good. For the best performance, install the notebooks locally.
This notebook shows a person tracking scenario: it reads frames from an input video sequence, detects people in the frames, uniquely identify each one of them and track all of them until they leave the frame.
In this case, we use the Deep SORT algorithm to perform object tracking. person detection model is deployed to detect the person in each frame of the video, and reidentification model is used to ouput embedding vector to match a pair of person images by the cosine distance.
