Abstract :
In this paper, we extend the set of RD optimization algorithms for the MDCT with the flexible time segmentation algorithm [1] and compare it with the existing single tree time segmentation algorithm [2]. We describe the application of transition windows in a time-varying MDCT and in RD optimal time segmentation algorithms. Experimental results show that the flexible time segmentation for a time-varying MDCT can outperform the Single Tree time segmentation algorithm in several cases.
