I first mentioned the Tesseract OCR library several years ago, and recently received a message from a visitor who was having difficulty going through those older tutorials and projects.
Here’s an excellent up to date set of resources from Loïs Di Qual for those looking to use the Tesseract optical character recognition library on iOS devices.
The resources include a working version of the library compiled for the iOS platform, a tutorial with source showing how to translate a page of text, and an Objective-C wrapper that makes working with Tesseract much easier.
1. A working tutorial and downloadable source code example using Tesseract to translate a page of text on an iOS device on Loïs’ blog here.
2. A compiled version of the Tesseract library for iOS devices can be found on Github here
3. An Objective-C wrapper that makes Tesseract much easier to use can be found on Github here.
Some awesome resources if you’re looking to use the Tesseract OCR library with Objective-C on the iOS platform.
