<p>PROBLEM TO BE SOLVED: To perform more accurate pattern matching of writing input by reducing the influence of discrete errors approximately unchangeably to affine transformation. SOLUTION: A pattern which is inputted by writing is sampled at specific intervals to obtain an input coordinate sequence and the pattern represented by this input coordinate sequence is connected by segments, approximated, and made into segments (a). The angles of the respective segments to the horizontal direction are found to generate contact angle distribution dataϕ(s). (b). At this time, the segment length along all the segments is divided by a specific number at equal intervals and a data sequence generated with contact angles obtained at the respective division positions is regarded as angle distribution dataϕ(i) (c). Thisϕ(i) is compared with a prepared standard pattern (angle distribution data) to obtain a matching degree (d).</p> |
