METHOD, DEVICE, AND PROGRAM FOR OBJECTIVELY EVALUATING VIDEO QUALITY

摘要

A motion vector or DCT coefficient which exists in the bit string of an encoded video and serves as a parameter representing the difference between scenes, or encoding control information or pixel information obtained by partially decoding the bit string of the encoded video is used for video quality objective assessment. It is consequently possible to save the amount of pixel information decoding processing that requires an enormous amount of calculation as compared to video quality objective assessment apparatus using pixel information obtained by decoding the bit string of an entire video. This allows to perform video quality objective assessment in a short time using an inexpensive computer.
