Abstract: A method for tracking an object in a sequence of video frames includes the following steps: creating a model with characteristic features for the object to be tracked; and performing a template matching algorithm in individual frames on the basis of the created model for determining a position of the object in the respective frame. An apparatus arrangement for performing the method includes at least one video camera (10, 12), at least one monitor (24, 26), one computer (20) and one input device (28) for an observer (22).

Abstract: The invention relates to a video tracking system which determines the position of objects, e.g. players in a football match, by evaluating video image information. According to the present invention, the video tracking system is additionally provided with an independent positioning system which is preferably used in instances when the video-based position detection is faulty or does not work at all. According to one embodiment, the independent positioning system is GPS based, each football player carrying a portable GPS module which transmits the position data to the system by radio. Additional data, such as heart rate or acceleration, can also be transmitted.

Abstract: Shoe having at least one pressure sensor provided in the shoe cushioning element, as well as system components for emitting, receiving and evaluating the signals of the sensor.

Abstract: System, consisting of at least one active or passive position detection system which sends data about the position of at least one athlete to a central evaluation unit; and a central evaluation unit which stores received positional data in a database, automatically calculates a movement pattern consisting of at least the covered distance and the mean velocity from the positional data, and represents the movement pattern on a display.
