In this paper, we present a robust framework for action recognition in video, that is able to perform competitively against the state-of-the-art methods, yet does not rely on sophisticated background subtraction preprocess to remove background features. In particular, we extend the Implicit Shape Modeling (ISM) of [10] for object recognition to 3D to integrate local spatiotemporal features, which are produced by a weakly supervised Bayesian kernel filter. Experiments on benchmark datasets (including KTH and Weizmann) verifies the effectiveness of our approach.
