摘要

离散余弦变换(DCT)是一种常用的图像和视频压缩方法。离散余弦变换近似是降低精确离散余弦变换计算复杂度的一种很好的方法，具有良好的编码性能。在本文中，我们回顾并比较了文献中一些最有趣的无乘法近似及其硬件成本。

Evaluation and Comparison of DCT Approximations on FPGA for Hardware Reduction

Discrete cosine transform (DCT) is commonly used in image and video compression. DCT approximations are excellent alternatives to reduce the computational complexity of exact DCT with good coding performance. In this article we review and compare some of the most interesting multiplication-free approximations in the literature and their hardware cost.
