rate-distortion based coding
Modeling of SSIM-based end-to-end distortion for error-resilient video coding
... We evaluate the performance on the platform of JM 15.1 [30], in which the SSIM index is adopted as an opti- mal quality metric. Five CIF sequences [27], five 640 × 360 sequences [27] and ten LIVE sequences [21,22] are ...
