== Sahana Eden Optical Character Recognition ==

Sahana OCR Module is responsible to generate OCR-able PDF Form for every resource Form available in HTML. There are two types of interfaces available based on the usecase.
1. Single Form Upload
  When there is human resource available to upload and verify the OCR-ed data individually then this interface can be considered. Here the user will upload a scanned Form, let eden OCR it, then he/she can verifies the data and update the database with this new record.

2. Bulk Form Upload
  When there is not enough human resource available to upload and verify the OCR-ed data then this usecase can be considered where scanned forms can be uploaded in bulk and verified later.

'''Phases'''

The workflow of OCR Module is composed of two phases:
1. Download PDF Form
2. Upload Scanned Form


== Download PDF Form ==
