本文提出了一种无书写框、无行方向的联机手写日文文本识别方法及其效果。通过规范化字符方向，甚至可以识别任意字符方向的文本。该方法评估的可能性组成的字符分割，字符识别，字符模式结构和上下文。字形结构的似然性考虑了由多个偏旁组成的汉字（子字形）中出现的字形的高度、宽度和间距。我们展示了新建模的可能性因素如何影响整体识别率。
This work presents a formalization of an on-line writing-box free, line-direction free handwritten Japanese text recognition and its effect. By normalizing character orientation, even text of arbitrary character orientation can be recognized. The method evaluates the likelihood composed of character segmentation, character recognition, character pattern structure and context. The likelihood of character pattern structure considers the plausible height, width and gaps within a character pattern that appear in Chinese characters composed of multiple radicals (subpatterns). We show how the newly modeled factors in the likelihood affect the overall recognition rate.
