Abstract:
A system for processing information signals, the system comprising:a processor operative to compare a first information signal to a second information signal in response to a user query, wherein the first information signal is selected by the user and the second information signal is stored in a database associated with the system, wherein the processor extracts color and texture information from at least the first information signal using a predetermined vocabulary comprising one or more dimensions, and generates a distance measure characterizing the relationship of the first information signal to the second information signal by applying a grammar comprising a set of predetermined rules to the color and texture information extracted from the first information signal and corresponding color and texture information associated with the second information signal, wherein the processor receives the first information signal in the form of an input image A submitted in conjunction with a query from the user, and wherein the processor is further operative to measure dimensions DIMi(A) from the vocabulary, for i=1, . . . , N, and for each image B from an image database, to apply rules Ri from the grammar to obtain corresponding distance measures disti(A, B), where disti(A, B) is the distance between the images A and B according to the rule i.
