The National Institute of Standards and Technology (NIST) developed the Activities in Extended Video (ActEV) evaluations series to support the needs of the Intelligence Advanced Research Projects Activity (IARPA) Deep Intermodal Video Analytics (DIVA) Program. An activity for ActEV evaluation is defined to be “one or more people performing a specified movement or interacting with an object or group of objects”. ActEV is an extension of the annual TRECVID Surveillance Event Detection (SED) evaluation where systems also detect and track objects involved in the activities. Each evaluation will challenge systems with new data, system requirements, and/or new activities.
ActEV began with the Summer 2018 Blind and Leaderboard evaluations for 12 activities. The summer evaluation was followed by the ongoing Fall ActEV Self-Reported Evaluation which ended in Dec 2018 and included 18 activities. The Winter 2018, $50K ActEV Prize Challenge (ActEV-PC) the Leaderboard Evaluation Phase ended in March 2019 and ActEV-PC Independent Evaluation Phase is currently going on. The Summer 2019 ActEV evaluation will start in May 2019.
