摘要
二维离散余弦变换(DCT)在图像处理和视频编码中起到很重要的作用,近年来发展速度也很快。介绍DCT的各种快速算法,根据图象处理的特点和易于硬件实现的目标选择基于分布算法(distributed arithmetic-DA)的DCT结构来实现FPGA设计。
2D DCT plays an important role in image procession and video encoding, developing quickly in recent years. This paper introduces various arithmetic, according to the characteristics of image manipulation and is easy to the target of the hardware realization, based on the distributed arithmetic to realize the FPGA design.
