System for identifying freehand drawings.

摘要

A system for identifying freehand curve drawings has: an input section(1) for inputting a freehand curve drawing as a series of point data; a fuzzy-curve information generating section(13,14) for generating fuzzy-curve information from the series of point data by adding input vagueness information to each of the series of points; a segmentation section(15) for dividing the fuzzy curve information into a plurality of segments by evaluating a degree of standstill at each point; a curve-class identifying section(16) for identifying a curve class and a representative curve in the class by measuring a possibility of the curve class for each segment with respect to each of a plurality of curve classes; and a connecting section(17) for connecting representative curves by adjusting positions of the representative curves at each segment identified by the curve-class identifying section.
