Description: JPEG 标准的最新进展是 1996 年开始制定， 2001 年正式成为国际标准的 JPEG 2000 。与 JPEG 相比， JPEG 2000 作了大幅改进，其中最重要的是用离散小波变换（ DWT ）替代了 JPEG 标准中的离散余弦变换。在文件大小相同的情况下， JPEG 2000 压缩的图像比 JPEG 质量更高，精度损失更小。作为一个新标准， JPEG 2000 暂时还没有得到广泛的应用，不过包括数码相机制造商在内的许多企业都对其应用前景表示乐观， JPEG 2000 在图像压缩领域里大显身手的那一天应该不会特别遥远。 -JPEG standard on the latest progress of the development started in 1996 and in 2001 became the international standard JPEG 2000. Compared with JPEG, JPEG 2000 made substantial improvements, the most important of which is discrete wavelet transform (DWT) instead of the JPEG standard discrete cosine transform. The file size under the same circumstances, JPEG 2000 compressed images of higher quality than JPEG, precision small loss. As a new standard, JPEG 2000 has not yet been widely applied, including digital camera manufacturers in many enterprises have their applications are optimistic about the prospects of the JPEG 2000 image compression areas prone to the day should not particularly remote.

Description: A series of .c and .m files which allow one to perform univariate and bivariate wavelet analysis of discrete time series. Noother wavelet package is necessary -- everything is contained in this archive. The C-code computes the DWT and maximal overlap DWT. MATLAB routines are then used to compute such quantities as the wavelet variance, covariance, correlation, cross-covariance and cross-correlation. Approximate confidence intervals are available for all quantities except the cross-covariance and cross-correlation.
A set of commands is provided. For a description of this example, please see http://www.eurandom.tue.nl/whitcher/software/. -A series of. C and.
