| Abstract: | The conventional visibility function of a still image is extended to a spatio-temporal visibility function for image sequences. The visibility of impairment noise is subjectively measured as a function of both spatial and temporal gradients by an A/B sequence test. Some characteristics of the spatio-temporal visibility function are presented such as approximated forms and comparisons with spatial visibility functions.<> |
