How do I decide when to use Amazon Textract vs Amazon Rekognition's TextDetect method?
My usecase is click picture from mobile and convert image data into text and store into AWS RDS.
If there is simply random text in the picture, then use Amazon Rekognition. It will find text in any location.
Amazon Textract is designed for converting paper documents into organized data. It will probably not work well with a random picture (although I haven't tried it so I can't be certain!).
