Sample Study of Elver Behaviour Using Computer Vision

Computer vision for automated tracking is one of the topics of research and knowledge acquisition on migratory behavior. In this research, some elves were marked with four colors: red, orange, blue, and green, with single or double markings, and then introduced into an experimental medium and, a large database was collected by collecting many video observations. Elvers is segmented by background subtraction method and their motion information is extracted by connecting component classification. Elvers tracking is carried out by a Kalman filter, in order to improve the detection through local search focused on location prediction and path filtering to reduce estimation error.
