| 摘要: |
| 将小波理论应用于视频和图像的压缩是目前国内外十分重视的图像压缩技术。小波分析技术和多分辨分析理论改善了基于分块DCT变换的压缩编码技术的方块效应和飞蚊噪声的不足。小波理论将是未来视频和图像压缩标准的一项核心技术。目前基于小波变换的视频压缩算法主要可以分为基于空域运动补偿的小波视频编码(MC-DWT)、基于变换域运动补偿的小波视频编码(DWT-MC)和含运动补偿的三维小波视频编码(MC-3DWC),小波视频和图像压缩的发展及研究热点主要为小波图像压缩新技术的研究、运动补偿技术的研究、利用人的视觉生理特性进行小波视频和图像压缩的应用研究,以及小波视频压缩的应用研究。 |

| Abstract: |
| The compression of video-images using wavelet theory is an important image compression technique.The techniques of wavelet analysis and multi-distinguishing analysis improve diamond-effect based on compression coding of separate-block DCT transform and fly midge noise.The wavelet theory will be a core of video compression standard in the future.The algorithms of video compression based on wavelet transform includes MC-DWT,DWT-MC and MC-3DWC.The research hotspots of wavelet compression are the development of new techniques of wavelet image compression,movement compensation technique,application of wavelet video image compression in aid of human vision physiology and application of wavelet video compression. |
