A system and process for automatically learning a reliable color-based
tracking system is presented. The tracking system is learned by using
information produced by an initial object model in combination with an
initial tracking function to probabilistically determine the
configuration of one or more target objects in a temporal sequence of
images, and a data acquisition function for gathering observations
relating to color in each image. The observations gathered by the data
acquisition function include information that is relevant to parameters
desired for a final color-based object model. A learning function then
uses probabilistic methods to determine conditional probabilistic
relationships between the observations and probabilistic target
configuration information to learn a color-based object model
automatically tailored to specific target objects. The learned object
model is then used in combination with the final tracking function to
probabilistically locate and track specific target objects in one or more
sequential images.
