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: 伪彩色处理是指将黑白图像转化为彩色图像，或者是将单色图像变换成给定彩色分布的图像。由于人眼对彩色的分辨能力远远高于对灰度的分辨能力，所以将灰度图像转化成彩色图像表示，就可以提高对图像细节的辨别力。
伪彩色处理的基本原理是将黑白图像或者单色图像的各个灰度级匹配到色彩空间的一点，从而使单色图像映射成彩色图像。对黑白图像中不同灰度级赋予不同的彩色。
-Pseudo-color processing refers to the black-and-white images into color images or monochrome images will be converted into the distribution of a given color image. Since the human eye to distinguish color of gray is much higher than the resolving power, it will be gray-scale images into color images that can improve the discriminability of image detail. Pseudo-color processing is the basic principle of single-color or black and white images of various gray-scale image to match that color space, so that monochrome images into a color image mapping. Black and white images of the different gray-scale to give a different color. Platform: |
