The real-time detection of concealed threats is critical for protecting pub- lic transportation , sports arenas , and other open , difficult-to-secure envi- ronments .

tecting threats in the complex en- vironment of crowds carrying ev- eryday items remains a challenge .

The Hierarchical Inference for Volumetric Estimation ( HIVE ) is a custom deep convolutional neu- ral network architecture that inter- prets volumetric video generated by standoff , active-RF imagers for standoff concealed threat detec- tion to enable new approaches to protect people and infrastructure in areas where traditional security checkpoints are not feasible .

New sensing technologies , such as standoff active-RF imaging , can help securi- ty screen customers and bags quickly without af- fecting the flow of traffic .

However , accurately de-

Example uses of fusion between RF and color video for operational setting .
