检测Tesseract OCR Java实现的大小字体大小

Question

Is it possible to OCR a picture and identify different sizes of fonts in the picture using Tesseract OCR. If yes, do I need to use any other 3rd party library or can I use pure Java. For an example,

I want to detect the headline and the content of a newspaper by using the font size.

Any help regarding this matter would be appreciated.

Answer 1

您可以使用ResultIterator.WordFontAttributes API方法（ 使用Tess4J在Java中的示例 ）来检索已识别文本的字体信息，包括字体名称和大小。

Answer 2

Tesseract的hOCR输出包括可用于确定大小的行和单词的边界框，并且可以通过打开hocr_font_info配置变量将其配置为还包括输出中字体的hocr_font_info值。
