摘要：

Spatio-temporal pattern sensitivity has been studied by means of psychophysical tests on five subjects. The study has been undertaken to characterize human visual perception of typical coding artifacts of video sequences. The paper presents the experiments that have been carried out and the particular stimuli used for the study. The characteristics of human vision inferred from the experiments are used to parameterize a proposed spatio-temporal vision model. (C) 1998 Elsevier Science B,V. All rights reserved.
