摘要： A method for classifying an object in image data to one out of a set of classes using a classifier, said image data comprising an image of the object, each class indicating a property common to a group of objects, the method comprising the steps of obtaining said classifier used to estimate for an input feature vector a probability for each of the set of classes, one probability indicating whether the input feature vector belongs to one class; extracting a feature vector from said image data; using the obtained classifier to estimate the probabilities for the extracted feature vector; and evaluating the estimated probabilities for determining whether the object does not belong to any one of the set of classes based using a quality indicator.

摘要： A hand-held device for authenticating a marking on an object, said marking exhibiting a viewing-angle dependent light reflection spectrum. The device includes an imager for receiving light from said object and generating image data that include spectrum information, a marking detector for detecting marking image data associated with said marking in said image data, a parameter evaluator for determining a value of a predetermined spectrum parameter based on spectrum information of at least a part of said marking image data, an angle estimator for determining a value of a viewing angle between said imager and said marking associated with a determined value of said spectrum parameter, and an authenticator arranged for making an authentication decision based on at least two spectrum parameter values and their associated viewing angle values.
