The Method and Devices for Research the Parameters of the Human Visual System to Video Quality Assessment

摘要

The susceptibility of distortions introduced by compression from the point of view of human perception is an important area of research. The ultimate purpose of video quality assessment is to emulate the performance of the biological visual system. Perceptual distortion models have proven successful in describing spatial coding in all human visual systems. However, the question of how the visual regions of the human brain process temporal information have received significantly less attention. Based on the researches of limit to human vision, here we offer a method, software, and test equipment for research and measure the characteristics of human visual systems. This set forms and evaluates stimuli with a specified combination of spatial, temporal, and color characteristics, which differ in a narrowband enough spectrum for measurements.
