| 摘 要： | 提出一种新的手写汉字识别结果可信度的测定方法．该方法将各种识别结果的正确率作为测定识别结果可信度的绝对尺度，以各候选字的相对邻近度为基础定义了测定可信度的一种新的相对尺度，并将这两个绝对尺度和相对尺度相结合来全面测定可信度．通过基于HCL2000数据库的测试和在银行票据OCR系统中的实际应用，证明了这种方法的有效性．

| Abstract: | A new method of measuring the reliability of handwritten Chinese character recognition results is proposed. In this method, the right recognition rate is used as absolute criterion to measure the reliability of result, and a new relative criterion is defined based on each candidate character's relative neighboring degree. The absolute and the relative criteria are combined as a comprehensive criterion to measure the reliability. Results of experimentation based on HCL2000 and its application in Bank Check OCR system show the validity of the method. |
