OpenTLD

Why we included this project

OpenTLD is the reference C++ implementation of the classic TLD (Tracking-Learning-Detection) algorithm, the method that showed a tracker can hold onto an object even after it disappears and reappears in the frame. You define the object with a bounding box in a single frame, and the code tracks it, learns its appearance, and re-detects it whenever it shows up again. That still makes it a good place to start if you want to see how long-term tracking works under the hood, or if you need a compact baseline for real-time single-object tracking experiments on a webcam or video file. Be aware that the project is frozen and the algorithm has long been overtaken by deep-learning-based trackers, so this is code to read and adapt, not a maintained library to drop in. What survives is a clear, self-contained demonstration of the track-learn-detect loop, which remains instructive for coursework and for anyone tracing the lineage of modern tracking methods.
