WARNING... this project is more of a repertoire of AWS Lambda related functionality and examples...
It implements an AWS lambda function that automatically OCRs files/images dropped in one bucket and places them in another as text
To create a Lambda function as this one that uses native libraries used by the tesseract node module they must be included in the zip file that creates the Lambda function. You can use the linux ldd command to see a listing of libraries an executable uses. That is how I found the various libraries included here.
