## What it is
OpenTLD (Predator) is a MATLAB implementation of the Tracking-Learning-Detection algorithm for real-time 2D tracking of a single unknown object in video streams. The object is defined by a bounding box in one frame, and the system tracks, learns, and re-detects it as it appears and disappears.

## Use cases
- track a single object in a video given one bounding box
- re-detect an object after it leaves and re-enters the frame
- learn an object's appearance online during tracking
- research baseline for tracking-learning-detection algorithms
- process unconstrained video streams in real time

## When to choose
- you need the original TLD/Predator algorithm for research or comparison
- you work in MATLAB and want a classic single-object tracker
- you need tracking with automatic re-detection of occluded objects

## When to avoid
- you need a maintained or production-ready tracker
- you need multi-object tracking
- you want a modern deep-learning-based tracker
- you need C++ or Python support without porting

## Facets
