Hi,
there´s a great article about OCR(Optical Character Recognition) on codeproject.com. You should really read through it, it is a very comprehensive article.

Thanks,but how can it worked?what is the feature vector path?when i run the program it is wanted by the software?

That is the definition provided by the author:

The feature vector is simply the collection of the features of every pixel sorted by the track i.e. check the position of each pixel and add its properties to the feature vector. E.g. if we have two pixels lie in sector 1 and track 1 with the same relation of 4 then in cell4 in the relations table the one in t1 and s1 will be incremented twice since there are TWO pixels having this property

Actually it´s a tutorial with a source code attachment, so you can just implement the code in your application I think.

Nice Regards
