Fi there! Thanks for the time you spent on answering these questions.Actually what i tried to succeed was to create executables on windows platform.The programming environment i am using is Borland C++ builder 6.The thing is that i manages to include everything that was necessary for the deskew procedure to build(although i had lots of warnings.I can include the text result of the warnings if you are interested).The executable correctly works on the test_bin.ong file.On the test_gray.png file i see in the command prompt that sauvola technique starts working.Also, on the debugging procedure i went inside the conneceted component labelling thing!But as i moved on i noticed that this search function never ends.Actually the value of iter now (i am debugging it the same time i write this message) is 1996685 (almost 2million iteration without breaking!). Do you think that the code is correct and the problem is in the windows staff i use?I know that ocropus is still working only in unix systems.But i would like to inform you that the executables i managed to create for the binarization (2 executables,for the otsu technique and for the sauvola technique work fine!!). It would be interesting to inform me in which number of iteration (in the CTextlineRASTBasic::search function) the for loop stops!! I am really temptaded to finally make it! Another thing is the lack of documentation for the class methods and the class hierarchy!Do you plan on including documentation in the next version of ocropus? Thanks for your time! Giorgos Louloudis

How long does it take for you? Is the memory consumed by the program growing with time (it is a good sign)? Does it run out of memory?The search function tries to find the highest quality (longest) text-line in the page. The skew angle of that line is used as the skew estimate of the page. The reason for this being slow for this particular image is the presence of half-tone style noise. To better handle this type of images, you need text/image segmentation.Cheers,Faisal 2008/9/11 Giorgos Louloudis <[EMAIL PROTECTED]> I only created a c++ console application making use of the main-ocr-deskew-rast.I managed to create a project in order ot be able to deskew png images.in the folder there exist two png images test-bin.png and test-gray.png. for the first one everything works fine.For the second one it seems that the program stays inside the for loop of the function i described you.I discovered that after thorough debugging!Are you sure that this search functions works well?and what is the meaning of that function?Thanks for your time Thomas!I think we have met at ICDAR2007 in CurutibaGiorgos Louloudis Date: Thu, 11 Sep 2008 10:49:47 -0700From: [EMAIL PROTECTED]: [EMAIL PROTECTED]: Re: problem in search function of ocr-ctextline-rast.cc Please submit an issue to the issue tracker, with the input image and a small code snippet (preferably in Lua, but C++ will do).Cheers,Thomas On Thu, Sep 11, 2008 at 05:49, Italian Dream <[EMAIL PROTECTED]> wrote: Hello everyone!This is my first post!Well i am trying to create aconsole application using c++ builder making use of the deskew folderfiles.I created the project,corrected some things in order to be ableto build it.The problem is that although i managed to create an outputimage for the binary example, this is not the case for the grayscaleone.As i started debugging your code i noticed that the for loop thatstarts at line 217 (function CTextlineRASTBasic::search() ) neverstops!!!! I am not able to figure out what you try to search in orderto do anything inside this function.Hope that you notice anything andinform me please!!Thank you for your time!Giorgos LouloudisUniversity of AthensGreece_________________________________________________________________ News, entertainment and everything you care about at Live.com.
