An embodiment of USB device comprises a lookup table in a fixed electronically readable medium comprising a plurality of product identification information entries. The USB device also has an electronically readable index that selects one of the plurality of product identification information entries, and the vendor identification information is stored in a location separate from the index.

Look-up table based USB identification

Various backgrounds, forms, or templates are scanned, features are extracted, and the features are stored in memory. When a composite image is scanned (image of interest plus part of background), features are extracted from the composite image. Features in the composite image are correlated to stored background features to identify which background is present. If necessary, background features from memory are shifted in two dimensions to accommodate displacement of the background. Features corresponding to the background are deleted from the features in the composite image. For forms and templates, features are used to identify the background, and then the information is directly extracted from the composite image.
