We present a robust algorithm for point tracking on deformable objects. The key elements are the use of orientation selective rank features (ranklets), local filter adaptation and dynamic model update. A multi-scale vector of ranklets is used to encode a neighbourhood of each tracked point. The shape of the filters is optimised for each neighbourhood independently. Substantial appearance variations are catered for by maintaining a stack of models for each tracked point. This enables the system to recalibrate whenever the object reverts to its original appearance.
