A robust tracking algorithm is the cornerstone of
human motion analysis applications. This book
describes the tracking problem from three points of
view: punctual, regional and human pose modelling. In
the first one, the subject is considered as a compact
object, small and rigid. In the second one, it is
possible to model it as a set of connected regions,
each one with its own properties, and which junction
identifies the subject. The last point of view allows
us to identify the person as a non-rigid object, with
morphologic and dynamic properties which are
intrinsically human. Our goal consists in the study
and understanding of these three different stages in
which the human being can be modelled, as well as the
selection of the most suitable stage depending on the
application and the problem to be solved. The problem
will set the necessities and impose the limitations
in each time, due to internal factors (multiple
target, occlusions, camera location) or external
factors (cost, technical feasibility).
