- 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

- 为了实现彩色栅格地图道路的全自动提取，提出了一种闭环反馈提取彩色 栅格地图道路的方法。在地图图像数学模型的基础上，根据地图中对象的颜色特征对地图图 像进行规范化处理。在采用一些算法去除噪声后提取道路，对道路进行细化处理。依据道路 和噪声的特征建立一些判据判断道路的正确性，把道路的提取变成了根据判据不断修正道路 的循环过程，实现道路的全自动提取。试验结果表明了该方法具有较高的准确性、全自动化 和通用性。-color raster to the road map automati

- 我们知道，图像压缩就是要寻找高压缩比、并使压缩后的图像有合适的信噪比的方法，对压缩后的图像还要能实现低失真度地恢复图像。压缩性能的评价标准之一是图像能量损失和零系数成分值。能量损失越小，零系数成分值越大，图像压缩的性能就越高。 -We know that image compression is to find a high compression ratio, and the compressed image signal to noise ratio suitable metho
