| 9. | Meanwhile , with the intercross and penetration of different knowledge , wavelet theory has applied to many other fields successfully . for example , in the video coding , with the multiresolutional nature of wavelet analysis , three dimensional wavelet video coding has been shown to be competitive with standard coders . although 3 - d wavelet video coder usually require a larger buffer and incur a longer delay than standard coders , an important feature of the 3 - d wavelet approach is the support of scalabilities in the compressed video
同时，随着各门学科间的相互交叉与渗透，使得小波理论成功地在许多领域得到了广泛的应用。例如，在视频方面，由于小波本身的多分辨率的数据结构为支持可伸缩编码提供了一个良好条件，所以与标准视频编码相比，小波编码方法具有更大的发展前景。 |
