One of many important tasks in computer vision applications is real time object detection and tracking. Motion information and visual features, such as shape, color and texture, can be used to extract information from a video, to track and detect objects. Classical tracking algorithms work accurately in perfectly arranged conditions. Although, to efficiently tracking objects is a difficult task due to the variety of the conditions met. Significant problems occurred in computer vision systems, especially under the presence of noise, scene illumination, object shape variation and total or partial occlusion. The purpose of this thesis is to develop a method for effective object tracking and detection in complex scenes, such as sports game. In sports, the constant movement and the unexpected change of the velocity, is a common thing. Furthermore, sport players can frequently leave or enter camera’s field of view, but also occlude each other. A robust solution could combine temporal motion information and statistical analysis of the visual features. The proposed approach would be able to efficiently track targets in motion in real scenes.
