RESUMO

In this work we consider the problem of tracking human movements. The interest for this problem concerns the analysis and recognition of human motion used in a variety of applications, such as clinical gait analysis, improvement of the human performance in sports, ergonomics, choreography of dance, and so on. In particular, we treat this problem using markers attached or fixed to human body, different from the methods based on human body and their motion models. The use of markers allows us to get more precise results in applications, such as Biomechanics where this precision is very important. We present some algorithms for tracking markers in a sequence of images, consisting in: extraction (segmentation) of the markers, prediction of their position in the next frames, and their recognition and classification. The definition of these algorithms yields the implementation of systemts for human motion analysis based on normal CCD cameras, unlike the systems based on special optoelectronic devices.
