Wrong full page box in hocr output

[Arno Loo]

Hello,

I have a recurrent problem and I don't understand why it is happening : for many of the documents I have, Tesseract's hocr output is giving incoherent bbox for a few ocrx_word. These ocrx_words are always composed of a single character and their bbox takes the entire page, which is weird because these ocrx_words are part of ocr_lines which have correct bboxes.

In the example I provided, the ocrx_word is an error as it detects the line from the table as a |. But in most cases, the character read in the word is correct, only its bbox is wrong.

Is anyone knows why it is happening and how I could fix it ?

The parameters I use are nothing fancy :

tesseract input.jpg output -l eng -c tessedit_create_hocr=1

Thank you.

try the latest code: there was fix regarding bbox after releasing tesseract 4.0
