【摘要】 介绍了一个用于正颌外科的计算机辅助诊断系统。系统是基于Windows98操作系统,并用Visual C++v5.0开发的,主要包含4个部分:图象预处理、图象特征提取、计算特征值以及作初步诊断。利用直方图均衡、中值滤波、多尺度分析和边缘提取等算法对X光数字图象处理后,得到人脸的轮廓及其特征点。对这些信息运用灰度模板进行搜索和匹配后,就可以进行诊断。更多还原

【Abstract】 This article describes a computer system used for the assistant prescription of orthodentia surgery, which is based on Windows98 environment and developed by MS Visual C + + V5.0.This system consists main- ly of 4 parts:image preprocessing,pieking up image feature,computing the characteristic value and making gross prescription.By processing the digital x-ray image using such algorithms as histogram equilization,filtering, multi-scale analysis,pick up edges and so on,we can get the outline of human face and then picking up its feature point to make prescription by means of seaching and pairing using gray level mask.更多还原
