Description: 此设计要求能够实现将医学图像进行识别的过程，包括了图像预处理、图像特征提取及分类判决三大模块。在预处理这一步中主要实现的是将彩色图像转换为灰度图像，灰度图像的二值化，直方图修正，去除干扰、噪声以及差异，边缘增强等；第二模块是图像的特征提取。由于对象的物理与几何特性差异，在影像中表现为局部区域的灰度产生明显变化，形成影像特征，而图像特征提取就是对其进行加工、整理、分析、归纳以便提取构成目标影像的特征，得到能反映图像内容区别于其他事物的本质特征；分类判决作为第三模块，则是要在第二步的基础上采用某种分类判别函数与判别规则，通过对目标特征的分析和匹配来识别目标。-this design requirements to achieve medical image identification process, including the image preprocessing, Image feature extraction and classification ruling three modules.

Description: 这个是一个获取两个图像相似度的函数，对于图像处理和数字水印方面的编程者来说，会经常去计算两个图像的psnr值，从而来确定图像的相似度，使用matlab可以很方便的计算两个图像的psnr，但是由于matlab专业性很强，而且有没有版权保护，所以对于大批的使用VC语言的这方面的编程者，由于要经常使用而显得很麻烦。
通过调用get_psnr函数可以很方便的就得到两个图像的相似度。

(2)调用SiapCariRecursive来对目录中各文件进行处理,这里面又分好几层关系。
（a）锁定一些暂时不用的按键，使在检索处理过程中，不让用户操作，乱按。
（b）调用CariRecursive函数：功能是分别提取目录中各个文件，并进行计算颜色直方图。这个函数又分下面几层：
(i)循环递归调用CariRecursive，找到所选目录下是否有子目录，有子目录进入子目录先处理
(ii)调用ScanFile，提取子目录中的一个个文件。
(iii)上面一步中，每找到一个文件，就调用Madhosi，进行计算颜色直方图（这部分与第1大点中，对关键图处理过程一样），并与关键图的颜色直方图比较，得到相似度，最后在把相似度保存到ListBox中去，同时对应填入对应的文件路径。
(iv)循环至(i)直到目录中所有文件都处理过，才结束CauRecursive,退出该函数。
(3)根据ListBox里面的内容，调整ListBox的宽度。按相似度距离，按从小到大把各文件排列在ListBox中。-Due to the development of multimedia technology and fast expanding of visual information, an effective method is sharply needed to manage and retrieve visual information.

Description: Cervical cancer is one of the deadliest cancers known and is also a key research area in image processing. The main problem with this cancer is that it cannot be detected as it doesn’t throw any symptoms until the final stages. This is attributed to the cancer itself and also to the lack of pathologists available to screen the cancer. Here we have proposed a novel approach to classify the various malignancies in cervical cyto images using the textural properties of the cervical cyto image. For grouping the stages of the cancer we have employed a decision based support system that would help classify the stages of the cancer and help the pathologist detect the cancer better. The proposed image has been tested with a set of images and has proved to be efficient. Platform: |
