Contraband Segmentation of Compton Back-scattering Images Based on EM

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。

Abstract: 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.
