We have developed an algorithm capable of enforcing a shape correspondence between two views of the same object in different shape-states. 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].
