Ultra-fast tracking based on zero-shift points

A novel tracker based on points where the intensity function is locally even is presented. Tracking of these so called zeroshift points (ZSPs) is very efficient, a single point is tracked on average in less than 10 microseconds on a standard notebook. We demonstrate experimentally the robustness of the tracker to image transformations and a relatively long lifetime of ZSPs in real videosequences.
