Description: （利用GIF_LZW算法实现的）网络图片传输 技术特点 ~~~~~~~~ 一、使用TCP协议传输数据。理由：稳定性好。 二、使用字节数据流进行传输，理由： A:VB的String存在自动Unicode转换问题，影响速度； B:可以直接发送8位字节数据，不需要使用Base64编码，从而减少了编码时间。 三、使用GIF-LZW压缩算法压缩图像。理由： A:行程编码、Huffman压缩算法压缩率太低； B:JPEG压缩算法需要太多位运算，且运算量大（有专门MMX优化算法），不利于VB实现； C:GIF-LZW压缩算法压缩率较好，且我已想出VB语法下高效GIF-LZW压缩/解压算法。 四、使用“有序抖动”算法进行 色彩量化。理由：“有序抖动”处理的结果具有一定规律性，有助于LZW类算法压缩。-(using GIF_LZW algorithm) picture transmission network ~~~~~~~~ a technical features, the use of TCP to transmit data. Reason : good stability. Two, the use of byte data stream for transmission, reasons : A : VB String exist automatically Unicode conversion, the impact speed; B : can directly send eight bytes of data and do not need to use Base64 encoding, thereby reducing the coding time. 3, the use of GIF- LZW compression algorithm for image compression. Reason : A : itinerary coding, Huffman compression algorithm compression rate is too low; B : JPEG compression algorithm needs much-bit computing, and large amount of computation (with MMX specialized optimization algorithm), is not conducive to VB; C : GIF- LZW compression algorithm compression ratio better, and I have come up with un

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.

Description: 提出了一种基于 JPEG/JPEG2000相结合的医学图像感兴趣区域压缩方法。该方法对在人为选定
医学图像的感兴趣区域采用无损的 JPEG2000压缩 ,而对其他图像区域则采用高压缩比的 JPEG压缩,较好地解决了医学图像的高压缩比和高质量之间的矛盾。-Based on a combination of JPEG/JPEG2000 region of interest of medical image compression method. The method of artificially selected region of interest of medical images using lossless JPEG2000 compression, and on other image regions using high compression ratio of JPEG compression, a better solution to the medical image and high-quality high-compression ratio between the contradictions.
