Abstract

This paper describes an on-line handwritten Japanese text recognition method that is liberated from constraints on writing direction (line direction) and character orientation. This method estimates the line direction and character orientation using the time sequence information of pen-tip coordinates and employs writing-box-free recognition with context processing combined. The method can cope with a mixture of vertical, horizontal and skewed lines with arbitrary character orientations. It is expected useful for tablet PCs, interactive electronic whiteboards and so on.

在线手写日语文本识别,不受线方向和字符方向的限制
本文描述了一种不受书写方向(线方向)和字符方向限制的在线手写体日语文本识别方法。该方法利用笔尖坐标的时间序列信息估计直线方向和字符方向,并将无书写盒识别与上下文处理相结合。该方法可以处理具有任意字符方向的垂直、水平和歪斜线的混合。预计可用于平板电脑、交互式电子白板等。
