OCR Tools

Surya – multilingual document OCR toolkit

In Operation

Surya predicts line-level bboxes, while Tesseract and others predict word-level or character-level. Let’s test the software with the nyt.png image file from their GitHub repository.

It writes a JSON with the detected bboxes, and saves images of the pages with the bboxes if you include the --images option.

Here’s a generated image showing the bboxes.

Summary

Surya has just seen its first public release but it already looks promising.

We’ll look at the software in more detail once it has added text recognition and table and chart detection. We’ll then evaluate the software for inclusion in our OCR Systems roundup.

Given the weights are not open source, is this really compatible with an open source license? I’m not a legal expert.

This really needs text recognition. When is that going to be implemented?
