Abstract: We present a simple and straightforward derivation to implement active contours for tracking distributions (Freedman and Zhang, 2004) and its improvement, i.e., distribution tracking through background mismatch (Zhang and Freedman, 2005). In the original work, two steps are performed in order to derive the tracking evolution equations. In the first step, curve flows are derived using Green’s Theorem, and in the second step level set method is used to implement the curve flows, which seems to be somewhat complex. In our implementation, tracking evolution equations are derived directly by using variational theory. This is useful to understand the tracking method better. The final tracking evolution equations are identical to the previous work (Freedman and Zhang, 2004; Zhang and Freedman, 2005).
