From multiple video sequences - Observations of L1 (Sum of Absolute Transform Difference (SATD)) and Structural Similarity (SSIM) at sub-block (4x4) and (8x8) on H.264/AVC

Observations of L1 (Sum of Absolute Transform Difference (SATD)) and Structural Similarity (SSIM) at sub-block (4x4) and (8x8) on H.264/AVC Codebook:Below are the headings and an overall description.BlockSize SSIM OneMinSSIM1k Covariance AbsMeanDiff PseudoSSIM TradDistOnly the first two columns and the last column were used for the paper referenced.BlockSize – this will be 4 for 4x4, 8 for 8x8.SSIM – SSIM score as calculated using the implementation found within JM H.264/AVC.TradDist – This would refer to L1 or L2 norm of SA(T)D or SSE respectively.

OneMinSSIM1k, Covariance, AbsMeanDiff and PseudoSSIM refer to the development of the PsuedoSSIM score, a model to map traditional distortion metric assessment to SSIM values.This is concept is explained in: dx.doi.org/10.1109/BMSB.2013.6621695
