Abstract
A method of classifying an object, in particular of classifying a vehicle by evaluating the degree of correlation between an image data set corresponding to an image of at least part of the vehicle and each of a plurality of reference data sets each of which corresponds to a reference image of a vehicle comprises the steps of establishing the vehicle'"'"'s aspect and selecting the plurality of reference data sets from a larger group of such data sets on the basis of the vehicle'"'"'s aspect. By selecting from the larger group only those reference data sets which correspond to the vehicle'"'"'s aspect, faster classification is achieved for a given level of processing resources. Alternatively, for a given processing or classification rate, the level of processing resources may be reduced compared to the prior art.

- 29. A method of classifying an object by evaluating the degree of correlation between an image data set corresponding to an image of at least part of the object and each of a plurality of reference data sets each of which corresponds to a reference image of an object, wherein the method comprises the steps of establishing the object'"'"'s aspect and selecting the plurality of reference data sets from a larger group of such data sets on the basis of the object'"'"'s aspect.
- 38. Apparatus for classifying an object, the apparatus comprising processing means for evaluating the degree of correlation between an image data set corresponding to an image of at least part of the object and each of a plurality of reference data sets each of which corresponds to a reference image of an object, wherein the apparatus further comprises means for establishing the object'"'"'s aspect and means for selecting the plurality of reference data sets from a larger group of such data sets on the basis of the object'"'"'s aspect.

47. A method of classifying an object by evaluating the degree of correlation between an image data set corresponding to an image of at least part of the object and each of a plurality of reference data sets each of which corresponds to a reference image of an object, the method comprising:
-
receiving a series of images; identifying a set of images in the series of images containing a fiducial marker capable of identifying an object for classification; selecting an image from the set of images in which the fiducial marker is in a predetermined position; and classifying the object by evaluating the degree of correlation between image data sets for the object in the selected image with image data sets for reference images determined as appropriate to images with a fiducial marker in the predetermined position. - View Dependent Claims (48, 49, 50)
