摘要

本文比较了基于4 × 4块的离散余弦变换(DCT)与传统的8 × 8离散余弦变换(DCT)的性能，发现小尺寸的DCT适合使用低功耗设备的移动应用，因为实时应用需要快速的计算速度。在计算时间和客观质量的基础上，以峰值信噪比(PSNR)为基础进行比较。

Performance Evaluation of 4x4 DCT Algorithms for Low Power Wireless Applications

The paper compares the performance of 4 x 4 block based discrete cosine transforms(DCT) with conventional 8 x 8 DCT .The small size DCT is suitable for mobile applications using low power devices as fast computation speed is required for real time applications. The comparison is done on the basis of computation time and objective quality, based on PSNR (peak signal to noise ratio).
