Abstract: Presents an overview of metrics that can be used to quantify the amount of spatial and temporal information in a video sequence. By applying the metrics to the input and output video, the amount of spatial and temporal information that is lost by the digital video transmission system can be obtained. The spatial metrics are based on the Fourier transform of the image and the temporal metrics are based on the motion difference image.
