基于DSP的高性能静态图像压缩

摘要

Providing a low-cost solution on static image procession. In this system, digital signal processor(DSP) is the core of high performance compression and image data procession. The system uses CCD for getting digital image, uses a 16 bit fix-point DSP to perform fast discret cosine transform(DCT)arithmetic and image encoding and realizes a fast image compression in end. The compression result testifies the high performance of the system.%提供了一种低成本的数字图像处理解决方案.研究了以DSP为核心的高性能压缩和处理系统.系统使用CCD获取原始数字图像数据,采用快速算法实现了核心的二维DCT变换,经过编码后,在一个16位定点DSP上实现了快速图像压缩.实验证明,该系统性能良好.
