1. An inspection system comprising:

  • a. a radiation source;

    b. a detector array;

    c. an inspection region bounded by said radiation source and detector array;

    d. a processing unit, wherein, through operation of at least one processor, at least one memory, and programmatic instructions, said processing uniti. obtains data representative of a radiographic image;

    ii. segments said data based on radiation attenuation or transmission;

    iii. identifies at least one segmented area within said data representative of said radiographic image;

    iv. filters said at least one segmented area using at least one geometric filter;

    v. generates a plurality of feature vectors using said filtered segmented area; and

    vi. compares said feature vectors against predefined values to determine whether a high-atomic-number object is present.
