From what I have found I did following: 1) Download tess-two from gooogle git, 2) build with NDK 3) put *.so files (armeabi/v7,x86,mips) into /app/main/jniLibs/, 4) pack *.so into .jar file, put archive into app/libs/ and wrote dependency {} to it in gradle.build file I'm using Android Studio and when I write TessBaseAPI and hit Alt+Enter -> "add dependency to tess-two module" it automaticaly write import row: import com.googlecode.tesseract.android.TessBaseAPI;

When I try to install it the package is not found I tried adding rpmforge but to no avail. Any ideas from somebody that has done before or is familiar with adding and searching through repos? 回答1: I used this instructions and worked correctly in Centos Install Tesseract OCR libs from sources in Centos Download Leptonica and Teseract sources: $ wget http://www.leptonica.org/source/leptonica-1.69.tar.gz $ wget https://tesseract

What I am doing here is first I am cross compiling tesseract to generate lib file using this post http://robertcarlsen.net/2009/07/15/cross-compiling-for-iphone-dev-884 and then using the the demo application at http://robertcarlsen.net/2010/01/12/ocr-for-iphone-source-1080 , but the results far away than realistic. I am not able to resolve the issue or how to train tesseract so that it comes closure for practical usage. Please help. Thanks,

I can't find any full step-by-step instructions how to do that, so I hope someone can share an experience. I want to use something like that in my code: #include <tesseract/baseapi.h> #include <leptonica/allheaders.h> I know that I need to put some additional instructions to the .pro file (etc LIBS, HEADERS), but I don't know is there is any right way to do that. Qt 5.8 Windows 10 MinGW 32bit 回答1: The "with Qt" part is redundant, you don't

Here's the python code I am trying to run : img = cv2.imread(image, 0) api = tesseract.TessBaseAPI() api.Init(".","eng",tesseract.OEM_DEFAULT) api.SetPageSegMode(tesseract.PSM_AUTO) tesseract.SetCvImage(img,api) url = api.GetUTF8Text() conf=api.MeanTextConf() print('Extracted URL : ' + url) api.End() and this is what I get: Error opening data file ./tessdata/eng.traineddata Please make sure the

Xcode 4.6, iOS SDK 6.1, tesseract-ocr 3.02 Since the last OpenCV versions are built using libc++ , and tesseract-ocr is built using libstdc++ , they can't be used together in one xcode project. So, I'm trying to build tesseract using libc++. Using the script here (updating the base sdk and deploy target to 6.1), tesseract is being built just fine, and works in my xcode project once the C++ standard library is set to the compiler default. Than, I tried altering the script to build it with libc++, according to the answer here . I changed CXX to point to clang++ , and added -stdlib=libc++ to the

I am developing an OCR to detect credit card. After scanning the image I get a list of words with it´s positions. Any tips/suggestions about the best approach to detect which words correspond to each field of credit card (number, date, name)? For example: position = 96.00 491.00 text = CARDHOLDER Thanks in advance Your first problem is that most OCRs are not optimised for small amounts of text that take up most of the "page" (or card image, in your case) in spatially separated chunks. They expect lines, or pages of text from a scanned book or a newspaper. So straight away they're not likely to

I was hoping someone could tell me why it is my Tesseract has trouble recognizing some images with digits, and if there is something i can do about it. Everything is working according to test, and since it is only digits i need, i thought i could manage with the english pattern untill i had to start with the 7segmented display aswell. Though i am having a lot of trouble with the appended images, i'd like to know if i should start working on my own recognition algorithms or if I could do my own datasets for Tesseract and then it would work, does anyone know where the limitation lies with

1、创建 Project 2、配置 一、在 app 的 build.gradle 中添加依赖 implementation 'com.rmtheis:tess-two:8.0.0' <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" /> <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> <uses-permission android:name="android.permission.MOUNT_UNMOUNT_FILESYSTEMS" /> git 地址 4、测试 package com.example.imgpstrtest; import android.Manifest; import android.content.pm.PackageManager; import android.content.res.AssetManager; import android.graphics.Bitmap; import android.graphics.BitmapFactory; import android.os.Environment; import android
