1. A system for identifying a potentially threat-containing object that has been subjected to imaging using an imaging apparatus, comprising: a processor; and memory comprising instructions that when executed via the processor implement at least some of: an object partitioner configured to partition an image of an object into two or more object partitions by: projecting the image along a first Eigen vector, associated with a first Eigen value, to generate an Eigen projection; projecting the Eigen projection along a second Eigen vector, associated with a second Eigen value, to generate a one-dimensional projection, the second Eigen value less than the first Eigen value; and identifying peak modes in the one-dimensional projection, a first peak mode corresponding to a first object partition of the two or more object partitions and a second peak mode corresponding to a second object partition of the two or more object partitions; a layout vector generator configured to generate a layout feature vector corresponding to the first object partition based at least in part upon one or more features associated with the first object partition; and a threat determiner configured to compare the layout feature vector to one or more predetermined boundaries to determine whether the object is a potentially threat-containing object.
