AWS Rekognition -- How to Parse All the Text in an Image?

I am trying to parse text in an image of a restaurant bill. I've been able to set up the ruby AWS SDK which has the Rekognition client using this example. Moreover, locally I have been able to make a call to Rekognition, passing an image locally.

When I make the call with #detect_text (docs), I get a response and the response has TextDetections which represent either lines or words in the image. I would like however that response to only contain TextDetections of type LINE. Here are my questions:

  1. Is it possible to get a response back that only contains TextDetections of type LINE?
  2. Is it possible to increase the limit of words detected in an image? Apparently according to the docs:

DetectText can detect up to 50 words in an image That sounds like a hard limit to me.

  1. Is there a way I can get around the limit of 50 words in an image? Perhaps I can make multiple calls on the same image where Rekognition can parse the same image multiple times until it has all the words?

Yes. You cannot detect more than 50 words in an image. A workaround is to crop the image into multiple images, and run DetectText on each cropped image.
