The name “Predator” itself evokes relentless tracking of a prey, in this case, any object, face, finger, etc. in real-time and at seemingly lightning speed. The software also learns, and so gets better with time.
The real name of “Predator” is Tracking-Learning-Detection (TLD), the branchild and PhD thesis of Zdenek Kalal of the University of Surrey, UK. TLD is an algorithm for tracking of an object which is bound by a box. TLD simultaneously tracks the object, learns its appearance, and detects it whenever it appears. The result is a real-time tracking that learns from its errors and improves over time, making it ideal for people with motor disabilities.
Practical uses include human-computer interfaces (e.g. virtual mouse), face recognition (security devices), visual search, tracking a vehicle using an airborne camera, tracking of [rare] animals, and object-centric video stabilization.
