METHOD, DEVICE, COMPUTER PROGRAM, COMPUTER SYSTEM, AND COMPUTER-READ MEMORY FOR PRESENTING AND SEARCHING OBJECT IN IMAGE Russian patent published in 2003 - IPC

Abstract RU 2220452 C2

FIELD: presenting object appearing in image. SUBSTANCE: in processing images stored in multimedia database presentation of scaled curvature space is obtained for outline of object by smoothing down this outline to have at least one additional parameter reflecting distribution of shape and mass of smoothed version of source curve, and then scaled curvature space and additional parameters are linked to obtain object shape descriptor. This additional parameter may correspond to eccentricity or roundness of outline, highest peak in image displayed in scaled curvature space; it can be based on Fourier descriptors or Zernicke moments, etc. EFFECT: enhanced precision in searching for objects in images. 17 cl, 3 dwg
