Paper Abstract

This paper deals with human motion analysis without using markers. It presents a new approach of human motion tracking in three sequence of images acquired simultaneously by a calibrated vision system. The analysis process leads to the three-dimensional reconstruction of a superquadric-based model representing the human body. The motion on the images is first computed with an optical flow method; it is followed by a crest line detection and by the classification of the parts of the superquadric with a Least Median of Squares algorithm. The results presented in the following concern more specifically the analysis of movement disabilities of a human leg during the gait.
