MPEG artifacts post-processed filtering architecture

摘要

A more efficient and less memory-access intensive post-processing architecture to substantially reduce blocking and ringing artifacts from decompressed video image data is provided. The post-processing architecture in accordance with the present invention implements a "pipelined" filtering process wherein a filter buffer, a blocking filter, and a ringing filter are serially connected to each other. The serial connection allows decompressed video image data to be first provided to a blocking filter for substantially reducing blocking artifacts and then the de-blocked video image data can be provided directly to a ringing filter for de-ringing without the need of an extra memory access.
