Abstract: Summarizes detailed methods of measurement for two objective video quality parameters based on the Fourier transform image. This contribution was submitted to ANSI T1A1 prior to conducting the T1A1 subjective experiment (this experiment collected 625 mean opinion scores - i.e., 25 test scenes passed through 25 different video transmission systems that ranged in bit rate from 64 kb/sec to 45 Mb/sec). The video quality parameters presented here have demonstrated strong correlation to subjective evaluations of the video and can be used for in-service as well as out-of-service tests since low bit-rate features are extracted and compared from the input and corresponding output video images.
