4th ACM/IEEE ARTEMIS 2013 international workshop on analysis and retrieval of tracked events and motion in imagery streams

In this paper, we give a short summary of the papers proposed in ACMARTEMIS 2013 which is held in Barcelona Spain in conjunction with ACM Multimedia. The workshop handles the areas of features analysis both at low and high level for efficient events detection, retrieval of multimedia events and objects and video synchronization issues and also events and behavior recognition from visual data. All papers were classified into three session of a single track workshop. The first session named "Video Features and Scene Analysis"includes articles that handle low level and high level visual analysis appropriate for event detection. The second session entitled "Retrieval of Multimedia Objects/Events"applies schemes for media data retrieval and video synchronization. Finally the third session "Analysis of Visual Events"describes algorithms for detecting actions, behaviors and events in complex visual scenes.
