<p>In a data processing system for recognising a subject image (1), first processing means (2) is arranged to derive from the subject image (1) at least one graph having a plurality of points representing topographical data of the subject image (1). Second processing means (3) is arranged to create, for each of those points, attribute data representing at least one attribute of the subject image (1) corresponding to the respective point, which attribute is in addition to the topographical data. At least one correlation matrix memory (7) is arranged to provide at least part of storage means (4) arranged to store data of stored images; comparison means (5) arranged to compare the data of the subject image (1) with the stored data of the stored images; and identifying means (6) arranged to identify matches between data of the subject image (1) and the stored data. The data processing system may be used with advantage in recognising natural images e.g. human faces.</p> |
