Workshop: Making a Simple App to Read Printed Text using Tesseract (OCR)

Submitted Sep 10, 2013

To add the capability of reading some printed text into your application for further use!


Have you ever wanted to input some text by the user, and that was printed on the paper? This workshop will help you getting that text into your application, while maintaining user experience!

We’ll do this by using a fork of Tesseract Android Tools by Robert Theis called Tess Two. It is based on the Tesseract OCR Engine (mainly maintained by Google) and Leptonica image processing libraries.

The process starts by building and importing Tess Two, adding the code to capture & process an image from the camera, and then finally filtering that image for the text, ie. performing OCR.

We’ll also explore possibilities and use cases of this, for example searching, translating text, storing receipts digitally, etc.
