DT202A: The How and Why of Using Subjective Testing for Perceptual Quality Optimization


Widely hailed a powerful and promising means of improving existing video compression, perceptual quality optimization (PQO) integrates consideration of the human visual system into the video encoding process. How well PQO succeeds in improving human perception of videos is best measured by human subjects, through subjective testing. This talk describes how EuclidIQ uses subjective testing to measure the gains from and inform the further development of IQ264, our technology that integrates PQO directly into H.264 encoding and achieves 25% bandwidth savings on average relative to reference H.264 encoding at equivalent quality.
