METHOD, APPARATUS, COMPUTER PROGRAM, COMPUTER SYSTEM AND COMPUTER-READABLE STORAGE FOR REPRESENTING OBJECT IN IMAGE

摘要

PROBLEM TO BE SOLVED: To provide a representation of an object appearing in a still or video image, such as an image stored in a multimedia database, especially for searching purposes, and to a method and apparatus for searching for an object using such a representation. SOLUTION: The method of representing an object appearing in a still or video image by processing signals corresponding to the image includes steps of: deriving a curvature scale space (CSS) representation of the object outline by smoothing the object outline; deriving an additional parameter that is the circularity of a smoothed version of the original object outline; and associating the CSS representation with the additional parameter to form a shape descriptor of the object.
