This representation compares favorably in terms of versatility and controlability with other local contour representations that have been used previously for this purpose. The Hermite representation allows a compact representation of curved shapes, without the smoothing out of corners. It is also well suited for both interactive and tracking applications. The Hermite representation is used to formulate the contour finding problem as an optimization problem using a maximum a posteriori energy criterion.
Optimization is performed by dynamic programming.
