hOCR bbox viewer?

[matthew christy]

Does anyone know about a tool that already exists that allows you to see all the bounding boxes identified in Tesseract's hOCR output on one page?

Thanks,

Matt

Hi Matt,

I think you might find what you are looking for here:
https://code.google.com/p/tesseract-ocr/wiki/AddOns

Otherwise, you could code a simple jQuery script that traverses the
hOCR output and draws the boxes and the recognized text in HTML,
optionally drawing the page image behind the boxes. (I'd do it for a
fee :))

Hope this helps,
Dev

I wrote a very simple tool that does that called hocrdraw. It's in
my 'tesstrainingtools' repository:

Better late than never, but found this tool that will do what you want.

You just need to rename your hocr or html file (depending on version of tesseract) to xml.
