摘要
基于小波的视频图像压缩的理论,根据小波变换的基本特点,用小波视频图像处理的关键技术对现有小波视频图像处理技术进行分析,结合软件和硬件的实现方法提出小波视频图像处理的新方案。通过选取最佳的小波基和快速提升小波算法,实现了经小波变换处理后的图像细节部分清晰,层次感强,适合于高压缩比的应用领域要求。
Based on the theory of wavelet video image compression and according to the feature of wavelet transformation and applying to the key technology of wavelet video processing, this paper has analyzed the existing wavelet video image processing technology and tried to point out the new schemes of wavelet visual image processing to combine software with hardware. At last, with selecting the best wavelet radical and adopting optimal wavelet arithmetic, the definition of image detail is improved and the layer level is enhanced and the compression rate is heightened.
