Provides the ability to get more meaninful text out of common OCR outputs. It manipulates the Bounding Boxes of lines to rebuild a page layout to approximate human-reading experience.
Current OCR engines responses are focus on text recall. Ocrlayout tries to go a step further by re-ordering the lines of text so it'd approach a human-reading behavior.
When images contains a lot of textual information, it becomes relevant to assemble the generated meaninful blocks of text enabling better scenarios.
Another way to see would be to cluster the lines of text based on their positions/coordinates in the original content.
- Text Analytics you may leverage any Text Analytics such as Key Phrases, Entities Extraction with more confidence of its outcome
- Accessibility : Any infographic becomes alive, overcoming the alt text feature.
- Read Aloud feature : it becomes easier to build solutions to read aloud an image, increasing verbal narrative of visual information.
- Machine Translation : get more accurate MT output as you can retain more context.
- Sentences/Paragraph Classification: from scanned-base images i.e. contracts, having a more meaninful textual output allows you to classify it at a granular level in terms of risk, personal clause or conditions.
Today bboxhelper supports the output of

- AWS Textract Detects text in the input document. Amazon Textract can detect lines of text and the words that make up a line of text. The input document must be an image in JPEG or PNG format. https://aws.amazon.com/textract/features/ https://docs.aws.amazon.com/textract/latest/dg/how-it-works-detecting.html https://docs.aws.amazon.com/textract/latest/dg/API_DetectDocumentText.html
Our goal here is not to conduct a comparison between Azure, Google or AWS Computer Vision API but to provide a consistent way to output OCR text for further processing regardless of the underlying OCR Engine.
