Description: 这是一个关于基于混合编码的图象压缩技术的实现，现在勉强可以实现关于小波的图象压缩实现。此程序可以将BMP格式的图象经压缩后以JPG的格式存储起来！压缩比一般可以达到32:1。还可以显示编码压缩所耗时间-This is a mixed coding on the basis of the image compression technology, and now can barely be achieved on wavelet image compression achieved. This procedure can be BMP format images compressed by the JPG format to store up! Compression ratio generally can be reached 32:1. It also shows the time taken Coding Platform: |

Description: 本作品是基于Windows平台使用Visual C++工具开发的多文档应用程序。本课题组成员在对DICOM3.0医学影像存储与传输的国际标准和JPEG 2000静态图像压缩标准学习的基础上，实现了基于JPEG 2000标准的医学图像高效压缩功能，压缩比可在1～300间可调；同时该软件兼容JPEG压缩，压缩比可在1～100间可调。该软件操作简单、界面友好，是PACS系统的一个重要组成部分，对于缓解传输带宽和存储容量的压力具有一定意义。-of the book is based on the Windows platform using Visual C development tool for the multi-document applications. The members of the task group on DICOM3.0 medical imaging storage and transmission of international standards and JPEG 2000 Static state image compression standard on the basis of studies, Based on the realization of the JPEG 2000 standard medical image compression function efficiently, compression ratio can be an adjustable-300; The software also compatible JPEG compression, compression ratio in a ~ 100 adjustable. The software is simple, friendly interface and PACS system is an important component of the For ease transmission bandwidth and storage capacity of the pressure with a certain sense. Platform: |

Description: 一种实用的数字图像压缩方法解振东，章三妹(成都理工大学信息工程学院，成都610059)摘 要：提出以C++Builder 6．0为开发平台，以其所提供的TJPEGImage为核心，实现真彩色图像的压缩，为工程实际的应用提供了一种非常实用的压缩手段。该方法减少了大量程序代码的编写工作。实验表明，当综合压缩比设为65时，压缩图像与原图像相比并无明显变化，由此可见，压缩效果令人满意。-a practical method of digital image compression solutions Zhendong, Chapter Sanmei (Chengdu University of Technology and Information Engineering College, Chengdu 610059) Abstract : C Builder 6.0 development platform to the provision of core TJPEGImage to achieve true color image compression. for the practical application provides a very practical means of compression. The ways to reduce the large number of code-writing. Experiments show that when integrated compression ratio is set to 65 hours, compressed images compared with the original image and no noticeable change, it can be seen that Compression satisfactory.
