摘    要:对小波变换原理及DM6446平台架构进行了探讨,并在DSP平台上设计实现了一个图像压缩系统。该系统选用提升小波变换算法对图像进行整数到整数的变换,再对变换结果进行嵌入式零树编码,实现图像压缩。实验测试该系统对静态图像进行101∶的压缩率下还能获得很好的图像质量,且系统集成度高,成本低,为实时应用环境下的图像压缩提供了一个很好的范例。

关 键 词:DM6446  提升小波变换  图像压缩

Abstract:This paper focuses on the wavelet transform and the architecture of the DM6446.An image compression system has been designed and tested on DSP.The system firstly transforms an image from integer to integer with lifting wavelet transform algorithm and then encodes the transformation result with embedded zero tree of wavelet to compress image.The experiment shows that the system can achieve good effect for static image compression under 10:1 ratio.The system is high in integration and low in cost.It provides an instance for image compression in real time application.
Keywords:DM6446  lifting wavelet transform  image compression
