| 摘 要： | 数字胸片放射图像由于具有很宽的动态范围，普通的图像后处理方法难以获得满意的效果。采用按解剖区域的自适应处理方法可以获得比较好的效果，但需要进行图像的自动分割。本文介绍一各肯效的肺部区域的自动分割方法。该方法根据胸片图像直方图的特征，自动确定肺部区域和给膈及下膈膜区域的阈值。

| Abstract: | It is difficult to process digital chest image with ordinary method because of the wide dynamic range of chest radiograph. Anatomically adaptive processing is a better method for chest image, but it needs automatic segment ation of the image. In this paper, an effective method for segmenting lung regions from digital chest radiograph is presented. This method automatically calculates the lung/mediastinum subdiaphragmatic threshold according to the histogram of chest image processed. |
