I am interested in using OCR to extract bold and italic words from a simple text. For example, if I input a clear image with text like so:

"The quick brown fox jumps over the lazy dog."

I would like to get an output like so: bold("brown", "jumps"), italic("lazy")

I have looked into doing this with OCRopus or Tesseract, but the documentation is poor and I can't tell if it's possible, or how to do it if it is.

回答1:

There is such function in Tesseract 3.0.1, from trunk. A new class is added to the API - ResultIterator, which has the following function you are interested in:

 WordFontAttributes(bool* is_bold,
                    bool* is_italic,
                    bool* is_underlined,
                    bool* is_monospace,
                    bool* is_serif,
                    bool* is_smallcaps,
                    int* pointsize,
                    int* font_id).  

Actually you can see it yourself from here.

The Tesseract 3.0x's XML-based hOCR format includes character attributes. You may want to try that.
