Picture Quality Assessment System by Three-Layered Bottom-up Noise Weighting considering Human Visual Perception
Takahiro Hamada, Satoshi Miyaji, Shuichi Matsumoto · SMPTE Journal · 1999
Video compression technologies, such as MPEG-2, are now standardized, and a number of video codecs based on these standards are being developed in many organizations, for use in digital television broadcast and transmission services. The degradation in picture quality produced by video compression is so complicated for human eyes to evaluate that neither a simple signal-to-noise ratio (SNR) nor detailed objective assessment parameters are accurate for this measurement. Studies on picture quality assessment have been conducted based on human visual perception models, which have led to an applicable modeling of the visual process.
