Description
Claims (1)
- Способ идентификации зачеркнутых символов при распознавании рукописного текста, характеризующийся делением распознаваемого изображения на области, выявлением областей, содержащих рукописные символы, применением структурных и признаковых классификаторов для распознавания и проверки правильности распознавания символов, использованием по крайней мере одного структурного классификатора как основного инструмента распознавания символов, выбором наиболее подходящего из нескольких вариантов символов, если на предыдущем этапе не удалось распознать символ однозначно, отличающийся тем, что распознавание символа включает по крайней мере выполнение следующей последовательности действий: распознавание символа по крайней мере одним дополнительным признаковым классификатором символов зачеркивания, осуществляющим одновременное сравнение с символом зачеркивания и по крайней мере одним похожим на него обычным символом, идентификацию символа как зачеркнутого в случае большего соответствия признакам символов зачеркивания.
