State of Objective Measurement Tools
This paper explores the challenges associated with assessing video quality. Many factors affect the video before it gets to the TV: compression, image processing, scaling, decoding, and transmission. To isolate their video algorithm, companies perform verification using subjective and objective video assessment techniques. While it would be far cheaper, to perform only objective test, nothing beats the human eye. Thus, Objective video quality measurements and Subjective video quality assessment are complementary rather than interchangeable. Subjective assessment is appropriate for research related purposes; objective measurements are required for equipment specifications and day-to-day system performance measurement and monitoring.
