Jaka Krivic and Franc Solina (2003) Contour based supequadric tracking. In: Knowledge-based intelligent information and engineering systems KES, September 2003, Oxford, UK.
This paper proposed a technique for tracking a supequadric-modelled object over a monocular video sequence. The object is currently modelled with a single supequadric. Object's position and orientation in the first frame of the sequence are assumed known. A frame in a sequence is first processed to find object's contour. Contour is determined by extracting edges on the frame in the vicinity of model's contour from the previous frame. The model's relative translation and rotation parameters are then calculated by fitting model's contour to the frame's contour. This fitting is achieved by minimizing the cost function, which is based on model to image mapping.
