Действительно ли вывод hocr Тессеракта содержит ограничивающие рамки и уровни достоверности для каждого символа?
вTesseract FAQ они говорят, что вы можете:
Как я могу получить координаты и уверенностькаждый персонаж?
Есть два варианта. Если вы не хотите заниматься программированием, вы можете использовать выходной формат Tesseract hocr (подробности см. На странице руководства Tesseract).
Но когда я создал образец вывода hOCR (это файл .html), ограничивающие рамки и уровни достоверности были доступны толькона уровне слов.
Я что-то здесь упускаю?
Я добавил пример ввода / вывода в качестве иллюстрации (размер входных данных изменен).
