Abstract
A method and apparatus for processing an observation of an object to be classified, the method comprising using a particle filter in which an observation of an object to be classified is used to weight particles on a plurality of models for the object. The method may further comprise performing at least one further iteration of using the particle filter to weight the particles on the plurality of models for the object using a further observation of the object to be classified. The method may further comprise providing respective classification probabilities that each respective model corresponds to the object based on the weightings of the particles of the respective model. Each of the respective particles may be divided into a respective plurality of sub-particles.

18. A method of processing an observation of an object to be classified, the method comprising:
-
receiving one or more possible models for the object defined in terms of an observation parameter as a function of a measurement variable; for each model, defining a respective set of one or more particles in the model; performing an observation of the object at a value of the measurement variable to provide a sensed value of the observation parameter; and weighting the particles according to the sensed value of the observation parameter. - View Dependent Claims (19, 20, 21, 28, 29, 30, 31, 32, 33, 37, 38, 39)
