Abstract

A series of measurement techniques (including measurement of the image on the display) are employed to determine the severity of motion errors, in order to gauge their effects on subjective evaluation of image quality and interpretability, and to identify and eliminate sources of motion errors. High performance display systems are increasingly being used for playback of moving imagery, making the accurate depiction of motion more important than ever. Higher definition formats drive systems harder, and source image motion can result in gross motion errors in the image seen on the display. Contributing factors can be choice of content, compression and transmission, graphics engine, and physical display device. Such motion errors can significantly impact perceived motion imagery quality and the perceived quality of the content, the server, and the display device. The NIST Motion Image Quality project is concerned with: (1) perceived image quality, and (2) motion image interpretability. The project uses both subjective analysis and quantitative measures of image characteristics. In the course of producing and collecting video content for subjective analysis, the project has encountered combinations of source and display system that produce severe motion artifacts that clearly affect image quality, and appear to impact interpretability as well. The apparent severity of the effects varies somewhat by the display technology used (DMD, LCD, CRT), which may indicate differences in the ways the display systems react to incoming signals.
