OCCLUSION TOLERANT PATTERN RECOGNITION

摘要

A method of identifying an object using a model based on appearance parameters derived by comparing a series of images of examples of that object, the model including a pre-learned estimated relationship describing the effect of perturbations of the appearance parameters upon an image difference, the image difference comprising a set of elements describing the difference between an image of an object generated according to the model and an image of the object itself. During searching for an object using the model, the set of elements comprising the image difference is compared to corresponding elements of a threshold vector, and only those elements of the image difference having values less than the corresponding elements of the threshold vector are used in the identification of the object, the remainder of the elements of the image difference being discarded.
