Deterministic tracking using active contours
Thesis (MScEng (Electrical and Electronic Engineering))--University of Stellenbosch, 2005.
This thesis relates to the problem of deterministically tracking an object that moves in a video sequence. A variety image processing and contour fitting algorithms and techniques are discussed. The tracking algorithm fit B-spline templates as is set out in the work done by Blake and Isard. The method builds on the concept that only certain deformations of the moving object's bounding curve is allowed. This is governed by projection into a subspace that allow only the wanted deformations. The deformations are restricted to be mostly linear, but small, nonlinear deformations can also be accomodated.
