Contraband detection system and method using variance data |
摘要 |
A technique is disclosed for detecting contraband by obtaining image data from a computed tomography machine and generating variance data and a variance map from the image data acquired. The method includes obtaining a mean density value and a variation value for each voxel of the image data, segmenting the voxels into discrete objects, and determining whether any of the discrete objects is contraband.
