Postprocessing system for removing blocking artifacts in block-based codecs |
摘要 |
Video signal post-processor de-blocks signal by processing block edges, particularly vertical and/or horizontal neighboring pixels. Depending on boundary condition, received signal is filtered using smoothing LPF function. Low-memory post-processor system neither requires DCT block characteristics nor blurs image edges close to block boundary.
