Summary of Lecture:
Automated target tracking and recognition (ATR) is an important capability in many civilian applications. ATR systems usually comprises several stages with the ability to detect, track and recognize targets. In this talk, we mainly focus on the tracking and recognition aspects for infrared (IR) imagery. The major challenge in vision-based ATR is how to cope with the variations of target appearances due to different viewpoints and underlying 3D structures. Both factors, identity in particular, are usually represented by discrete variables in most existing ATR algorithms. We propose a new couplet of identity and view manifolds for multi-view target modeling that is applied to automated target tracking and recognition (ATR). The identity manifold captures both inter-class and intra-class variability of target appearances by a continuous identity variable, while a hemisphere-shaped view manifold is involved to account for the variability of viewpoints. Combining these two manifolds via a non-linear tensor decomposition gives rise to a new target generative model that can be learned from a small training set and generalized to various known and unknown targets under arbitrary views. Not only can this model deal with arbitrary view/pose variations by tracking along the view manifold, it can also interpolate the appearance of an unknown target along the identity manifold. We also develop a particle filter-based ATR algorithm where the proposed model used for shape matching. The proposed algorithm is tested against the recently released SENSIAC ATR database and the experimental results validate its efficacy both qualitatively and quantitatively.
