摘要： A character recognition system includes a character input device, such as a stylus and tablet or optical scanner, for receiving inputted characters, and a processor. The processor determines which of a number of model characters best matches the inputted character. To that end, the processor compares each inputted character to each of a plurality of classes into which the model characters are organized. Specifically, the processor extracts a feature value vector from the inputted character, and compares it to the mean feature value vector of each class. The processor recognizes the inputted character as the model character corresponding to the mean feature value vector which is closest to the feature value vector of the inputted character. The processor also constructs the database from multiple specimens of each model character. The processor organizes the specimens of each model character into multiple classes. The processor then determines the mean feature value vector of each class.

摘要： An optical character recognition screen editing process is performed efficiently and only when necessary. The process is ordered so that editing is performed in increasing order of work intensity. That is, less "expensive" (i.e., less time consuming) correction methods are performed first, as a filter for more "expensive" correction methods. In the preferred embodiment, individual character are corrected first, information fields are corrected second, and entire forms are correction last. Preferably, the individual characters may be collected from a number of forms before being displayed for correction.
摘要翻译：仅在需要时才有效地执行光学字符识别画面编辑处理。该过程被排序，以便以增加的工作强度顺序执行编辑。也就是说，首先执行更少的“昂贵”（即较少耗时）的校正方法作为用于更“昂贵”校正方法的滤波器。在优选实施例中，首先校正单个字符，第二次校正信息字段，并且最后校正整个形式。优选地，可以在显示用于校正之前从多个形式收集各个字符。
