文档介绍：摘要
在过去的十年里,需要存储、传输和处理的信息数量成指数级数地增加。这主要归因于两项技术的发展。一是多媒体系统在众多领域的应用,过去的计算机只能处理数字和文本信息现在却已代之以声音、图片、影像;的大发展,它使信息能被许多人共享。正是由于这些原因,计算机医疗、远程医疗服务因为其的快速、便捷,正被越来越多的医疗机构所采用。这也就要求我们采用更先进的图像处理技术和更适合网络传输的图像格式。
本文介绍的是一个基于VC++。该系统可以处理由高倍放大镜采集到的血液切片照片,并将照片根据需要转换成更适合网络传输的图片格式。该系统可以方便地应用于临床医学诊断和网络远程医学诊断上。文中主要讲述了数字细胞图片处理(平滑、图像二值化、色彩空间转换、空洞填充、腐蚀去噪)、识别(梯度修正、细化、中心点标注法)、统计与JPEG(DCT变换、量化、Huffman编码)及JPEG2000压缩编码(小波变换、EZW编码)。
在设计中我们分成了以下三个模块来实现系统的功能:
(1)血液细胞图像处理、分析、识别、统计。
(2)JPEG图像压缩编码。
(3)基于小波变换的JPEG2000图像压缩编码。
在文中,我们首先给出了图像处理、图像识别、EZW编码、Huffman编码、DCT变换的有关算法;然后给出了细胞统计识别、JPEG压缩编码、JPEG2000压缩编码的系统模型,最后介绍了系统的设计方案、实现过程及在VC++。

ABSTRACT
In the past ten years,the information needs to be stored,transmited and processed had increased can attribute this fact to two technology:One is the using of mulitimedia in many this puter can only process numbers and words,however,now it can process images,sound and movies instead;Another is the great development of which makes the information can be shared by its convenient and high-speed,puter and disease diagnoses online service for long-distance is used by more and more hospitals. This means we need advance image processing solutions and better image form suits for transmission.
In this paper,we will introduce a blood cell image processing system based on VC++ system can process cell images which collected by magnifying glass connected to puter,and the system will transform the images into small ones which suit for transmission according to the system is convent to the diagnosesing of disease and long-distance medcial online service.
The paper focuses on the digital image processing(smooth, binary image,rgb to hsi,fill holes, erosion),recognition(gradient,revise,thin,center point marking),statistic and pression encoding of jpeg (DCT,Huffman encoding) and jpeg2000(wavelet,EZW encoding).During the design,we devide the system int
