Researchers at the University of Granada (UGR) in Spain have developed an artificial intelligence program that automatically detects in real time when a subject in a video draws a gun.
The researchers developed the model by analyzing major motion pictures and low-quality videos from YouTube in which guns get a lot of screen time.
The algorithm was able to analyze five frames per second, in real time, with a 96.5% detection rate.
UGR professor Francisco Herrera says the model could be combined with an alarm system and implemented inexpensively using video cameras and a computer with moderately high capacities.
He notes this type of deep learning model represents a major breakthrough over the last five years in the detection, recognition, and classification of objects in the field of computation identification.
