Resumo(s)
In this paper we provide an analysis of rate-distortion (R-D) relationship in an H.264 codec using as quality metric Structural Similarly Information (SSIM). This study focus on the quantization parameter, namely
rate-quantization (R-Q) functions and distortion-quantization (D-Q) functions.
Together, these functions allow a better understanding of the rate-distortion (RD)
behaviour of an H.264 video codec, which is the key issue of optimum bit allocation. Initial results are presented and discussed.
