Java OCR
Good evening I'm doing a project where I have to develop a language preferably java an application of a photograph has to take the digits of registration (plate) and see if the car is in the database so I've been researching there is an api sdk and OCR (Optical character Recognition) is a technology to recognize characters from an image file,
Someone can give me some tips on how I can do this and where to start
Thanks in advance.

Re: Java OCR
Google 'java OCR api' and also see the following: format - Java based OCR SDK/API - Stack Overflow
I have not used the packages in that link myself, but can guess that they vary in accuracy so I would try as many as you can with a training and test set to evaluate how they each perform (each algorithm is going to very in accuracy). I would also recommend perhaps using different feature extraction techniques and test for accuracy. FWIW I have written low level OCR tools and they are not trivial - often rely in a complex machine learning algorithm (neural network, PCA, etc..) that require lots of training and testing to even come close to reproducible and accurate results.
