问题 I wrote a basic app using Tessnet2 and now trying to move it to a WebForms website. Copied the logic etc. but when I run it I get an error message(Exception: DllNotFoundException) "An exception of type System.DllNotFoundException" occured in Tesseract.dll but was not handled in user code. Additional information: Failed to find library "liblept172.dll" for platform x86." As said above, this code works as a C# console and after applying necessary logic to move it to the website I thought I

Tessnet2 Init-Method crashes with certain tessdata path

问题 I'm using the Tessnet2 assembly (which uses Tesseract) to do OCR. Unfortunately the programm crashes without any exception after I call the init method: tessnet2.Tesseract ocr = new tessnet2.Tesseract(); ocr.Init(@"D:\Test\Tessdata\german", "deu", false); The german folder contains the following tesseract 2 word data: deu.DangAmgigs deu.freq-dawg deu.inttemp deu.normproto deu.pffmtable deu.unicharset deu.user-words deu.word-dawg If I use null for the path it works fine because I installed

问题 i'm using the tessnet2 wrapper to the Tesseract 2.04 Source on windows XP, configured it to work with x86. TessarctTest project main function contains: Bitmap bmp = new Bitmap(@"C:\temp\New Folder\dotnet\eurotext.tif"); tessnet2.Tesseract ocr = new tessnet2.Tesseract(); // ocr.SetVariable("tessedit_char_whitelist", "0123456789"); ocr.Init(@"C:\temp\tessdata", "eng", false); // List<tessnet2.Word> r1 = ocr.DoOCR(bmp, new Rectangle(792, 247, 130, 54)); List<tessnet2.Word> r1 = ocr.DoOCR(bmp,

What files should be included in the tessdata folder after training tesseract?

问题 I am using tesseract as the OCR engine for my ANPR application. I have trained tesseract 3.01v with the numberplate font. But I need to know: Which files should be included in the tessdata folder? Should I use the same tessdata folder where tesseract 3.01v is installed? I have trained with tesseract 3.01v and I am using tessnet2 in my code so will it be a problem? Following is the code that I tried it with but it keeps exiting from the DoOcr() method. List<tessnet2.Word> ocrText = new List

问题 I have created a console application. Added a reference to tessnet2_32. Ocr ocr = new Ocr(); using (Bitmap bmp = new Bitmap(filename)) { tessnet2.Tesseract tessocr = new tessnet2.Tesseract(); tessocr.Init(@"C:\temp\tessdata", "eng", false); ... I also tried changing "C:\temp\tessdata" to C:\work\ConsoleApplication3\ConsoleApplication3 C:\work\ConsoleApplication3\ConsoleApplication3\tessdata C:\work\ConsoleApplication3\ConsoleApplication3\bin\debug C:\work\ConsoleApplication3

问题 I am writing a program that uses OCR (tessnet2) to scan an image file and extract certain information. This was easy before I found out that I was going to be scanning attachments of PDFs from an Exchange server. The first problem I am working on is how to convert my PDFs to BMP files. From what I can tell so far of TessNet2, it can only read in image files - specifically BMP. So I am now tasked with converting a PDF of indeterminate size (2 - 15 pages) to BMP image. After that is done I can
