摘要
介绍了数字图书馆信息资源平台构建的实现原理和方法。利用JPEG2000图像压缩标准对数字图书馆信息资源中的大量图片信息采用离散小波变换(DWT)压缩技术来提供比JPEG更高的压缩效率,设计了一种数字图书馆信息资源存储和组织中的文件系统结构,并基于Ecllipse平台利用Java语言实现了数字化信息资源平台的开发。
This paper introduces the implementation principles and methods for constructing digital library's information resource system,and by using JPEG2000 image compression standard to achieve a higher compression rate(compared with JPEG) for large amount of image based on DWT(discrete wavelet transformation),designs a file system structure in digital library's information storage and organization,and based on platform Ecllipse and Java language,realizes the development of a digitalized information resources platform.
