Systems and methods for detecting threats and contraband in cargo

A computer readable non-transitory medium comprising a plurality of executable programmatic instructions executed by a processor for implementing a process for processing a radiographic image to identify whether at least one firearm is present in an object, said plurality of executable programmatic instructions comprising:

• programmatic instructions, stored in said computer readable non-transitory medium, for receiving the radiographic image of the object;
• programmatic instructions, stored in said computer readable non-transitory medium, for applying a neural network to the radiographic image to minimize errors in an association of portions of the radiographic image with one or more predetermined features;
• and
• programmatic instructions, stored in said computer readable non-transitory medium, for generating a visual demarcation of an area in the radiographic image to identify a presence of the at least one firearm in the object based on the association with minimized errors.
