tesseract

Do you know of step by step guide of how to use bins and dlls in http://www.pixel-technology.com/freeware/tessnet2/ I spent 2 days trying to use this by when compiling i am being asked for a dll that do not exist in the zip file i downloaded from the site. Any help will be greatly appreciated. You need the Leptonica DLL for Windows. You can download it from http://www.leptonica.com/download.html , or direct link to the specific zip is here . You need to copy the lib & include folders into the Google Tesseract vs2008 folder (ie, create vs2008\lib and vs2008\include). elconomeno download the

Now I want to install Tesseract but I also need to install Leptonica. I did not find any clear instruction how to do it in windows. For Leptonica I do not want to install Visual Studio. So could anybody provide clear instructions how to install leptonica and tesseract on Windows without Visual Studio to use in anaconda ? Thanks. 回答1: Here is simple set of steps to have tesseract 3.05 dev version as of 04/22/2016 working both on windows 7 and

I am already able to deskew documents, however it still might occur, that a document is upside down and it needs to be rotated by 180°. Using tesseract 's layout analysis feature it should be possible to determine a document's orientation using this code: tesseract::TessBaseAPI api; api.Init(argv[0], "eng"); api.SetImage(img); api.SetPageSegMode(tesseract::PSM_AUTO_OSD); tesseract::PageIterator* it = api.AnalyseLayout(); tesseract::Orientation orient;

In the FAQ it says I need to change the value of "NON_WERD" and "GARBAGE_STRING" but they do not exist in Tesseract 3. 回答1: According to http://code.google.com/p/tesseract-ocr/wiki/FAQ , you change these variables: enable_new_segsearch 1 language_model_penalty_non_freq_dict_word 0.2 language_model_penalty_non_dict_word 0.3 Increase their values to make Tesseract more biased to dictionary words. Note: You must set enable_new_segsearch , otherwise they'll have no effect

Shortly, I want to make the pre-processing procedures before OCR with the suggestion comes from ABBYY 's technology . There are two parts in article: Background Filtering : separate text strings from background. Adaptive Binarization : make lines and words will be correctly detected and higher recognition accuracy will be reached. And they try to impact on characters. I wonder are there any ways to achieve them by using opencv ? Any suggestions or sample codes would be appreciated. I would encourage you to use this code: http://liris.cnrs.fr/christian.wolf/software/binarize/ In particular wolf

I am working on OCR using tesseract. I am able to make the application working and get the output. Here i'm trying to extract data from an invoice bill and getting the extracted data. But the spacing between words in input has to be similar in output file.I am now getting each words and coordinates.I need to export to text file according to coordinates Code Sample : using (var engine = new TesseractEngine(Server.MapPath(@"~/tessdata"), "eng", EngineMode.Default)) { engine.DefaultPageSegMode = PageSegMode.AutoOsd; // have to load Pix via a bitmap since Pix doesn't support loading a stream.
