摘要
En 中文
Preprocessing of image and video sequences with spatial filtering techniques usually improves image quality and compressibility. In this correspondence, we present a block-based, nonlinear filtering algorithm based on singular value decomposition and compression-based filtering. Experiments show that the proposed filter preserves edge details and can significantly improve compression performance.
