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

Is it normal that tesseract does not recognize this word in this image?

问题 I need to extract words from small images like this: I am using tesseract from the command line with spanish language option, like this: tesseract category.png -l spa -psm 7 category.txt I think that this text must be easy to parse by the OCR but the word is not recognized. I am using -l spa for spanish language and -psm 7 because the image has got only line (anyway if I don't use -psm parameter the result is the same). This is the result: s…"… I am using this build with the lang package:

PyTesseract call working very slow when used along with multiprocessing

问题 I've a function that takes in a list of images and produces the output, in a list, after applying OCR to the image. I have an another function that controls the input to this function, by using multiprocessing. So, when I have a single list (i.e. no multiprocessing), each image of the list took ~ 1s, but when I increased the lists that had to be processed parallely to 4, each image took an astounding 13s. To understand where the problem really is, I tried to create a minimal working example

Java OpenCV + Tesseract OCR “code” regocnition

问题 I'm trying to automate a process where someone manually converts a code to a digital one. Then I started reading about OCR. So I installed tesseract OCR and tried it on some images. It doesn't even detect something close to the code. I figured after reading some questions on stackoverflow, that the images need some preprocessing like skewing the image to a horizontal one, which can been done by openCV for example. Now my questions are: What kind of preprocessing or other methods should be

How do I improve the accuracy of the OCR text from Tesseract?

由 守給你的承諾、 提交于 2019-12-18 17:54:19
问题 I created a basic app for recognizing text using the Tesseract API from Google and integrated it with my camera app. It works fine but the only problem is the accuracy, as sometimes the text is recognized as a random set of characters and I guess the accuracy is about 50 percent. Further, when it tries to scan more than four words in an image, the app crashes. String ocrText = baseApi.getUTF8Text(); baseApi.end(); where baseApi is the object of the Tesseract API class. Do I need to use a

Including Tess4J to a Java project as library in Eclipse

由 余生颓废 提交于 2019-12-18 15:49:46
问题 I have an so far empty and clean Eclipse Java project. What do I have to do to use Tess4J as library for my web service that I want to develop? Is it even possible to use it as library for an Android project? (would be shortcutting a lot) There is an issue regarding .tif with android that I came across. Tess4J is a wrapper for native code, because tesseract-ocr is written in C/C++. That I've got so far. But how to include this wrapper into my project? I've googled a lot until I have decided
