Activity Analysis Of Spectator Performer Videos Using Motion Trajectories, Anish Timsina Aug 2016

Activity Analysis Of Spectator Performer Videos Using Motion Trajectories, Anish Timsina

Department of Computer Science and Engineering: Dissertations, Theses, and Student Research

Spectator Performer Space (SPS) is a frequently occurring crowd dynamics, composed of one or more central performers, and a peripheral crowd of spectators. Analysis of videos in this space is often complicated due to occlusion and high density of people. Although there are many video analysis approaches, they are targeted for individual actors or low-density crowd and hence are not suitable for SPS videos. In this work, we present two trajectory-based features: Histogram of Trajectories (HoT) and Histogram of Trajectory Clusters (HoTC) to analyze SPS videos. HoT is calculated from the distribution of length and orientation of motion trajectories in …
