摘要
本文对视频序列的三维小波变换压缩编码算法进行了研究。与传统方法相比,基于三维小波变换的视频序列压缩算法更能消除帧间的冗余度,获得较高的压缩比,因而是一种很有潜力的编码方法。目前,基于三维小波变换的视频序列压缩编码的具体算法也比较多,本文对其中三种有代表性的算法进行了研究,并分析了这三种算法的优劣,并对其进行了展望。
In this paper, some compression algorithms which are based on 3D wavelet transform for video sequence are considered, Compared with traditional methods, these algorithms can remove the redundancies between frames effectively, and obtain high compression ratio, because of this, they may be very potential. At present, there are many compression algorithms which are based on the 3D wavelet transform, this paper discusses three of them which have special representation and analyses the advantages and disadvantages of these algorithms. At the end, the future trend of these algorithms is pointed out.
