Machine-Learning Algorithm Aims to Identify Terrorists Using the V Signs They Make

Every age has its iconic images. One of the more terrifying ones of the 21st century is the image of a man in desert or army fatigues making a "V for victory" sign with raised arm while standing over the decapitated body of a Western victim. In most of these images, the perpetrator's face and head are covered with a scarf or hood to hide his identity. That has forced military and law enforcement agencies to identify these individuals in other ways, such as with voice identification. This is not always easy or straightforward, so there is significant interest in finding new ways.
