Abstract: Discusses a real-time personal computer-based system for characterizing spatial (e.g., blurring) and temporal (e.g., jerky motion) distortions in a compressed digital video system. Comparisons with a high quality non real-time laboratory version of the same image processing algorithms demonstrates that measurement system gain and frequency response must be calibrated to assure repeatability of objective performance parameter results.
