摘要
PROBLEM TO BE SOLVED: To provide a characteristic extraction method for searching for a three-dimensional model by comparing characteristic values of a border pixel pattern of the three-dimensional model being searched (with those of a known three-dimensional model), and to provide an annotation system.SOLUTION: Characteristic values of a boundary pixel pattern is obtained by sorting differences between an observed pixel and adjacent pixels to positive and negative for each border pixel, and extracting a histogram of appearance frequency of each. Comparison of the characteristic values of the border pixel pattern involves assessing dissimilarity, in terms of sum of maximum values of appearance frequency histograms for the border pixels extracted from each depth buffer image, between a known three-dimensional model and a three-dimensional model being searched using all combinations of the multiple viewpoints as an index.
