Abstract

The applicability of MPEG video coding can be improved by scaling the algorithmic complexity and resource usage to the desired application and device. This paper presents a new DCT computation technique of which the quality and amount of computations is maximized for a limited number of operations. For halved computing resources, about 2-4 SNR dB improvement was obtained when compared to a diagonally oriented computation of coefficients, matching with the conventional MPEG scanning.

资源受限系统的新型可扩展DCT计算

MPEG视频编码的适用性可以通过将算法复杂度和资源使用比例调整到所需的应用程序和设备来提高。本文提出了一种新的DCT计算技术，在有限的运算次数下实现了计算质量和计算量的最大化。在计算资源减半的情况下，与传统的MPEG扫描相比，对角线方向的系数计算提高了约2-4个信噪比dB。
