A python library that reorders bounding boxes generated by OCR engines into the correct reading order
Project description
bbox-align (In development)
bbox-align is a Python library that reorders bounding boxes generated by OCR engines into the correct reading order. It aims to group bounding boxes into logical lines (even when documents have folds, irregular spacing, or distortions) and sort them for downstream use in document processing.
Installation
pip install bbox-align
Prereqs: Python 3.8+
Concept
Two bounding boxes are considered inline if the y-coordinate of one box's vertical center lies within the top and bottom bounds of the other box.
What if the bounding boxes are cross?
Now the bounding boxes are reflected
