原木断层扫描图像的自动分割研究

Research on automatic segmentation of log computerized axial tomography

首先介绍了医学数字成像标准(DICOM)及其文件格式,在此基础上使用灰度值统计图和灰度值直方图技术,对原木轴间断层扫描图像进行了分析。找出了原木图像的分布特点和规律,并实现了原木图像和背景图像的自动分割。为原木缺陷的自动识别,提供了有利的条件。

Standard and file format of Digital Imaging and Communications in Medicine(DICOM) is introduced first, then analyzes log computerized axial tomography based on technology of gray scale statistics and gray scale histograms. We find distributing characteristic and rule of log image, and automatically segment log image from background image. It provides advantaged base of automatic recognition log disfigurement.
