Towards Measuring Perceptual Video Quality & Why
summary
Covers measuring perceptual video quality to guide bitrate and encoding decisions by comparing objective metrics (PSNR, SSIM) with perceptual alternatives. Discusses BD-Rate curves, existing rate-control approaches, shortcomings of objective metrics, and perceptual quality evaluation tools and methods for making reliable bitrate tradeoffs.
