Abstract: A method and apparatus for identifying a media item. The apparatus includes a module for receiving media items and capturing an image of a received media item. The method involves ascertaining external dimensions of the media item from the captured image; creating a monochromatic image based on high contrast boundaries within the captured image; matching the monochromatic image to one of a plurality of templates of media items of approximately the same external dimensions as the media item; and providing details of the matched template, including type and orientation of the media item corresponding to the matched template.

Abstract: A technique for use in automated recognition of a media item involves accessing a template that includes multiple segmentation maps that each is associated with one of multiple classes to which the media item might belong. For each of the multiple classes, the segmentation map is applied to an image of the media item to extract a feature set for the image, the feature set is analyzed, and an assessment is made as to whether the media item belongs to the class.

Abstract: A method for developing a template of a reference document, such as a bank note and using that template to validate other test documents. The method involves using images of a plurality of reference documents, such as banknotes and segmenting each image in a like manner into a plurality of segments. Each segment is then classified using a one-class classifier to determine a reference classification parameter. These parameters are used to define a threshold reference classification parameter. Optionally, the step of segmenting is optimized to determine a preferred number of segments, and a preferred combination of these for use in a subsequent validation process. Preferably, this is done using a stochastic algorithm such as a genetic algorithm.

Abstract: A technique for use in automatic validation of a media item involves accessing a template that comprises multiple one-class classifiers, each corresponding to one of multiple classes to which the media item might belong, and then applying each of the one-class classifiers to an image of the media item to generate a result set for each of the multiple classes. The result set for each media class is then analyzed to assess whether the media item belongs to that class.

Abstract: A method and apparatus for evaluating a soiling level of a media item, such as a banknote. The method comprises receiving an image of a media item including a plurality of pixels, each pixel having an associated intensity. Two sets of pixels are created, where each pixel in the first set has a higher intensity than each pixel in the second set. A representative intensity value from the first set and a representative intensity value from the second set are calculated. A soiling value from the ratio of the representative intensity value of the second set to the representative intensity value of the first set is calculated. The media item is captured if the soiling value fulfils a capture criterion.
