Outline Unusual Event Detection Video Representation Dynamic Sparse Coding Empirical Study Conclusions Outline Unusual Event Detection Video Representation Dynamic Sparse Coding Empirical Study. Such matrices has several attractive properties they support algorithms with low computational complexity and make it easy to perform in cremental updates to signals We discuss applications to several areas including compressive sensing data stream illinoisedu kyusvneclabscom Abstract Sparse coding of sensory data has recently attracted notable attention in research of learning useful features from the unlabeled data Empirical studies show that mapping the data into a signi64257cantly higher di - Israel .
