JPEG 2000是基于小波变换的图像压缩标准，由Joint Photographic Experts Group组织创建和维护。JPEG 2000通常被认为是未来取代JPEG（基于离散余弦变换）的下一代图像压缩标准。JPEG 2000文件的副档名通常为.jp2，MIME类型是image/jp2。 JPEG 2000的压缩比更高，而且不会产生原先的基于离散余弦变换的JPEG标准产生的块状模糊瑕疵。JPEG 2000同时支持有损数据压缩和无损数据压缩。另外，JPEG 2000也支持更复杂的渐进式显示和下载。 JPEG 2000是国际标准化组织（ISO）发布的标准，文档代码为ISO/IEC 15444-1：2000。虽然JPEG 2000在技术上有一定的优势，但是到目前为止（2006年），互联网上采用JPEG 2000技术制作的图像文件数量仍然很少，并且大多数的浏览器仍然不支持JPEG 2000图像文件的显示。但是，由于JPEG 2000在无损压缩下仍然能有比较好的压缩率，所以JPEG 2000在图像品质要求比较高的医学图像的分析和处理中已经有了一定程度的广泛应用。 (JPEG 2000 is based on wavelet transform the image compression standard, by Joint Photographic Experts Group organization to create and maintain.

JPEG 2000 also detrimental to support data compression and nondestructive data compression. In addition, JPEG 2000 also support more complex gradual display and download. JPEG 2000 is international organization for standardization (ISO) issued the standard, the document code for ISO/IEC 15444-1:2000. Although JPEG 2000 on the technology has certain advantages, but so far (2006), the Internet using JPEG 2000 technical production image file number still few, and most )

说明：  BP_Adaboost模型即把BP神经网络作为弱分类器，反复训练BP神经网络预测样本输出，通过Adaboost算法得到多个BP神经网络弱分类器组成的强分类器，利用此方法设计出强分类器。(The BP_Adaboost model uses the BP neural network as a weak classifier, repeatedly trains the BP neural network to predict the sample output, and uses the Adaboost algorithm to obtain a strong classifier composed of multiple BP neural network weak classifiers. This method is used to design a strong classifier.)
