Optical Flow MethodsEdit
Optical Flow Analysis can be used to determine pedestrian flow. http://www.wikipedia.org/wiki/Optical_Flow.
Pedestrian Tracking and TracingEdit
PeTrack - Automatic Extraction of Pedestrian Trajectories from Video Recordings In order to understand and thereupon to model the pedestrian dynamics, reliable empirical data of pedestrian movement are necessary for analysis and verification. The existing database is small, inaccurate and highly contradictory. Manual procedures for collecting this data are very time-consuming and usually do not supply sufficient accuracy in space and time.
