Description:

OCR is a format for representing OCR output, including layout information,
character confidences, bounding boxes, and style information. It embeds this
information invisibly in standard HTML. By building on standard HTML, it
automatically inherits well-defined support for most scripts, languages,
and common layout options. Furthermore, unlike previous OCR formats,
the recognized text and OCR-related information co-exist in the same file
and survives editing and manipulation. hOCR markup is independent
of the presentation.

Included command line programs:

- hocr-check -- check the hOCR file for errors
- hocr-combine -- combine pages in multiple hOCR files into a single document
- hocr-eval -- compute number of segmentation and OCR errors
- hocr-eval-geom -- compute over, under, and mis-segmentations
- hocr-eval-lines -- compute OCR errors of hOCR output relative to text
ground truth
- hocr-split -- split an hOCR file into individual pages
- hocr-merge-dc -- merge Dublin Core meta data into the hOCR HTML header
