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.
