摘要
X光片的自动校准能在放射科医师摄片时对感兴趣区域(ROI)提供聚焦功能,从而方便实际操作和提高摄片质量。本文提出了一种基于统计的X光片肺部区域自动校准算法,分析了单纯依赖图像灰度值信息的不足之处并提出解决方法。从试验结果和实际效果看,本方法能够对X光片中肺部区域实现自动校准,有着较好的应用前景。
Automatic lung region locating can be used to focus the ROI in X-Ray images. This can improve the quality of X-Ray images too. In this paper, a statistical-based method of automatic lung region focusing is proposed. After analyzing the defects of pure gray level method, we give our algorithm. Judging from the experiment testing, out method gives fairly good results.
