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.
