Help needed in understanding source. New to tesseract.

[Sashank gondala]

Hello,

      I am new to tesseract. I am working with a professor of mine, who is trying new methods in OCR for "Telugu" language. I want to implement those using tesseract. How do I understand the code flow,i.e., which files and functions are invoked sequentially in order to generate an output from an input image? I have read the document "Overview of tesseract" by Ray Smith and downloaded the source. Eg: I am looking for resources/ways that can make me understand stuff like, "tesseractmain.cpp is invoked first, then it calls a function from permute.cpp etc".

       Thanks.

If you start by learning C++ then you will realise the entry point to a C++ program (main), you can then trace the various calls either manually, methodically stepping through files and functions by searching. You could potentially look at tools that allow call stack debugging/tracing. I am not familiar with C++ but in Java and PHP you can bind into programs to see what the call stacks are.

Thanks for the reply. Tracing manually is too much of a pain in this case. I am looking for tools that help me in this regard.
