Does not work for a lot of reason 1) above 3.0.2 we cannot use bitmap in the line engine.process, because we have to convert the bitmap in tesseract .pix ... It is so hard to setup that the only way i got through is to downgrade to 3.0.2 version 2) Now that I am in 3.0.2 I do not have the folders x86 and x64 ! Why ?! I downloaded the tesseract data for 3.0.2 I putted them in the folder "tessdata" and when i try to run the program it says at the new tesseractEngine line: "missingmethodexeption 'Method not found: 'System.Reflection.Emit.AssemblyBuilder System.AppDomain.DefineDynamicAssembly(System.Reflection.AssemblyName, System.Reflection.Emit.AssemblyBuilderAccess)'.' " I'm getting tired of all thoses errors only occuring on my environment...

[@VIPICANDMBPRO]

Hi Tom Firstly I would like apologize for inconvenience. I think you would like you working on the new version but it not worked and you tried my tutorial and somehow visual studio can't download 2 two folder. I recommend you should install `System.Reflection.Emit` by command `Install-Package System.Reflection.Emit -Version 4.7.0`. I'm not sure it will help you resovel version 3.0.2 but you can try it with new version 3.3.0, because Tensseract 3.3.0 have dependencie with `System.Reflection.Emit` Thank you and have a great day.

Is That OCR can capture 'CAPTCHA' image? I study tesserect, with c# winform but....... Just normal image like this youtube can capture and get data, but captcha image cannot get string(or int) data...

[@VIPICANDMBPRO]

Hi Luc! I think it not recognize data in your captcha because your image not contain clean text.

[@TheGeardarko]

Gracias me servirá, también funciona con .Net Core

[@AMIRKHAN-dm2fm]

if there are some digits and characters combination the what i can do?

[@erickcarballo1454]

I have a problem with the carpet "tessdata", when i try for charge the image, the program give this error: Failed to initialise tesseract engine. Please, help.

[@VIPICANDMBPRO]

Hi Naruneki Gamer! Sorry late reply! I think you setting wrong path data directory for Tesseract Engine var ocr = new TesseractEngine("./tessdata", "eng", EngineMode.TesseractAndCube); Or you forget download data files for Engine. github.com/tesseract-ocr/tesseract/wiki/Data-Files#data-files-for-version-302 If you have any problem please let me know i will reply soon. Thankyou!

[@muhammadwajid3867]

great job. bro i want to creat a setup for capture data from a form which is wirtten in handwriting formate what i should do?

[@VIPICANDMBPRO]

Hi Muhammad Wajid! This is a good question! If you would like handwriting recognition you must training new dataset for you. I suggest you learning about TensorFlow or Accord.NET framework. I hope it will help you resolve your issue.

Hi Deepak Goyal! Here you are! Install Tessseract by Nuget: www.nuget.org/packages/Tesseract/ You can donload file file trainning for vervions 3.0: github.com/tesseract-ocr/tessdoc/blob/main/tess3/Data-Files.md For version 4.0: github.com/tesseract-ocr/tessdata_best

An unhandled exception of type 'System.InvalidOperationException' occurred in Tesseract.dll Additional information: Source bitmap's pixel format Format32bppRgb is not supported. my image format .bmp

[@VIPICANDMBPRO]

Hi Wisnu Jati Rogo Juni! Actually i don't know exactly root cause your issue. I'm not sure Tesserect not support bmp format because i never use bmp with Tesseract. But you can try with png format if Tesseract work we can say it not support bmp format. I think my tutorial will working old Tessarct version, If you use new version may be it not work. Please check one more times: 1. Add dataset (tranning file) for Tesseract? 2. Choose any cpu for Visual Studio If you have any problem please comment i will try help you in possible Thank you!

[@microsecure2612]

is it possible to add a code to this application in order to extract specific area from the image ?

[@VIPICANDMBPRO]

Sorry micro secure! I'm lost this code. But you can you try glass window to get text area. This is my code make glass window with WPF. Thank you for watching! drive.google.com/file/d/1sopx5o-AYD3-skYP9AtwNq-oR8lDyx2F/view?usp=sharing

[@aryantrivedi2151]

Hi there, I want to build one OCR on which I can train it for multiple types of images. Especially simple captchas. Can you help me?

[@VIPICANDMBPRO]

Sorry Aryan, i can't help you! But i will answer if i find solution. You can try research OpenCV or Aforge.Net, which may be useful.

[@shahbazsharif2907]

AOA bro i have tried this code in my application but its give me an error why this bro????

[@islamidunya114]

when i upload image that i was download from internet it is not working why?

[@VIPICANDMBPRO]

Hi Munib Habib! It's only working with image contain clear text, can you show me which image you would like text recognize?

[@TheAchyley]

How could I use the text as an Integer? This tutorial is awesome

[@VIPICANDMBPRO]

Would you like filter character if character is not number? You can try add this code below orc constructer. orc.SetVariable("tessedit_char_whitelist", "0123456789");

[@jacktk3129]

can you demo how tesseract works in mvc 6 core?

[@VIPICANDMBPRO]

Sorry, Now I don't have any .NET project when I have .NET project I will try demo tessract on MVC. I think it will working on MVC because Tesseract just a library. If you upload file image on server then server call code Tesseract to recognize character and response result to client. Thank you!

hello good work but i have an exception An unhandled exception of type 'System.Reflection.TargetInvocationException' occurred in mscorlib.dll Additional information: Exception has been thrown by the target of an invocation.

[@VIPICANDMBPRO]

Thank you your question! I think you should install "Visual C++ Redistributable Packages" for Visual Studio You can download here:www.microsoft.com/en-us/download/details.aspx?id=48145 You can reference this link: github.com/charlesw/tesseract/issues/245 I hope you can fix it!

[@sangkv97]

anh đã thử với biển số xe chưa ạ . Em có thử trên xamarin nhưng kết quả không ổn lắm

[@VIPICANDMBPRO]

Mình vẫn chưa thử chạy trên Xamarin! Cái này phụ thuộc yếu tố môi trường nhiều lắm bạn! Thường thấy người ta dụng API có license để làm việc. Mình phải xử lý ảnh trước đó rồi mới đưa cho thăng Tesseract xử lý nếu bạn đưa thẳng cho nó thì không khả thi.Cám ơn bạn đã quang tâm. À bạn có thể tìm hiểu thêm về OpenCV hoặc EmguCV để xử lý ảnh trước khi dùng Tesseract để nhận diện ký tự!

[@sangkv97]

Rất cảm ơn anh đã hồi đáp . Em sẽ thử qua tesseract một lần nữa . Nếu không khả thi , em sẽ chuyển qua API . Cảm ơn anh . chúc anh thành công !

[@letricuong2806]

@@VIPICANDMBPRO Cái này không đọc chính xác lắm, có lẽ do font. Mình đã tách ảnh số thành ảnh binary rất rõ nhưng hay đọc lẫn lộn. Đang tìm cách tranining

[@VIPICANDMBPRO]

Đúng rồi bạn nó phụ thuộc vào hình chúa ký tự phải rõ ràng và thuộc tập xác định của file tranning.
