PPT-Sparsity-Based Signal Models and the Sparse K-SVD Algorithm

Ron Rubinstein Advisor Prof Michael Elad October 2010 Signal Models Signal models are a fundamental tool for solving lowlevel signal processing tasks Noise Removal Image Scaling Compression. 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 Volkan .
