摘要

随着越来越多的多媒体内容以MPEG压缩格式传输和存储，对压缩域操作技术的需求也越来越大。介绍了一种对MPEG视频进行空间域缩放的有效方法。仿真结果表明，该方法在具有相当主观质量的前提下，比现有的压缩域处理速度快。

Compressed domain spatial scaling of MPEG video sequences

As more and more multimedia content is delivered and stored in the MPEG compressed format, there is an increasing need for compressed domain manipulation techniques. We introduce an efficient method to perform spatial domain scaling of MPEG video. Simulation results indicate that the proposed scheme is faster than the current compressed domain processes while having a comparable subjective quality.
