Emergence of The Contraband Object Based on The Compton Back-scattering

On the basis of the analysis of image in the Body Searching System based on the CBS, the paper brings forward segmentation arithmetic of the contraband object based on Mathematical Morphology and double threshold values.It is effective that adopting expansion accumulation arithmetic can avoid restraining noise and improve the object energy, judging contraband area by connectedness, finally making contrand emergy effectively through obtaining the data.
