摘要

The device has an allocator designed to allocate information concerning a gradient intensity and a gradient direction based on an allocation rule to an edge image in order to obtain edge type information. The rule is selected such that three different allocated edge types exist for a predetermined gradient direction, where the edge types reflect different gradient intensities. An edge histogram determination unit determines an edge histogram based on the edge type information such that the edge types with different gradient intensities are differentiated in the edge histogram. Independent claims are also included for the following: (1) a device for storing an image in an image database, comprising a device for determining an edge histogram of an image (2) a device for finding two similar images, comprising a device for receiving an edge histogram (3) a method for determining an edge histogram (4) a method for storing an image in an image database (5) a method for finding two similar images (6) a computer program having instructions to perform a method for determining an edge histogram.
