摘要
X射线康普顿背散射(CBS)技术是一项较新的射线安检技术,可以提高复杂背景下安检设备对爆炸物等有机违禁品的探测力度,这其中一个重要环节就是图像中有机违禁品的分割问题,本文分析了CBS技术成像图像的特点,有针对性地提出了一种基于EM聚类的图像中有机违禁品的图像分割方法,实验结果表明该方法具有很好的适用性。
Compton back-scattering （CBS） is a new technology for X-ray security inspection that can enhance accuracy of explosive detection, such as organic contraband. For this task, contraband segmentation of image is very important. This paper analyses the features of CBS image, and a algorithm for contraband image segmentation based on EM clustering technology is proposed. The test results show this algorithm has preferable applicability.
