Implementing a Video Quality Metric in the H.264/AVC Decoder
Grúbel, Michal ; Číka, Petr (oponent) ; Slanina, Martin (vedoucí práce)
In this diploma thesis an algorithm for the evaluation of picture quality of H.264-coded video sequences is introduced and applied. As a measure of picture quality objective metric the peak signal to noise ratio (PSNR) is used. While the computation of the PSNR usually requires a reference signal and compares it to the distorted video sequence, this algorithm is able to evaluate PSNR following the coded transform coefficients. Thus, no reference signal is needed.
