Abstract
Preprocessing of image and video sequences with spatial filtering tech niques usually improves image quality and compressibility. In this cor respondence, we present a block-based, nonlinear filtering algorithm b ased on singular value decomposition and compression-based filtering. Experiments show that the proposed filter preserves edge details and c an significantly improve compression performance.
