Update: the Suzuki cook-book for building on iOS still works, see https://tinsuke.wordpress.com/2011/11/01/how-to-compile-and-use-tesseract-3-01-on-ios-sdk-5/
About performance: we have observed only a relatively small performance gain with Tesseract 3.02 versus Tesseract 3.01 - something like 10s versus 11s - this is far from some estimates I have posted here quoting 2x performance improvements. Furthermore, I experimented with Tesseract 3.02 running with the Tess 3.01 training set and: 1. There are more accuracy errors: this is something Ray mentioned should be expected if running the new code with the old training set, because the new eng.traineddata has essential additional information for each character. 2. Speed is MUCH improved in that weird combination - 5.8s versus 11s! I am guessing that's because the missing additional data for characters causes new algorithms to be skipped. Can anyone shed some light? In general, does anyone know what's new in the Tess 3.02 training set? Is it the same set of fonts with extra data or does it add many new fonts?
