Abstract

We have developed an algorithm capable of enforcing a shape correspondence between two views of the same object in different shapestates. This algorithm, together with several other significant updates, has helped improve the performance of the Integrated Shape and Pose Model (ISPM) described in [1] by a factor of 10. The ISPM utilizes two flexible basis views to integrate the linear combination of views technique with a coupled-view Flexible Shape Model (FSM) [2]. As a proof-of-principle we have evaluated the performance of the improved ISPM in comparison to that of its predecessor [1] and of the conventional FSM [3], via two different databases. The results show that, unlike the FSM, the current ISPM is view-invariant and that, on average, it out-performs the FSM. It also out-performs the initial ISPM described in [1].
