Abstract
A method and apparatus for enhancing the video quality of compressed video signals adaptively removes distortions and ringing effects embedded in the decompressed images. The apparatus operates in conjunction with decoder devices installed in set-top boxes, satellite receivers, TV broadcast channel servers, digital still cameras, DVD players and recorders, large screen TV sets, media players, and the like.
Claims60
An apparatus comprising:
- an estimation unit to generate visual quality parameters that indicate the visual quality of decompressed video frames;
- and
- a decompressed video enhancer to substantially improve the visual quality of said decompressed video frames using their associated parameters.
A method comprising:
- estimating visual quality parameters that indicate the visual quality of decompressed video frames;
- and
- substantially improving the visual quality of said decompressed video frames using their associated parameters.
A computer product readable by a machine, tangibly embodying a program of instructions executable by the machine to implement a process, said process comprising:
- estimating visual quality parameters that indicate the visual quality of decompressed video frames;
- and
- substantially improving the visual quality of said decompressed video frames using their associated parameters.
