tesseract

问题 I am trying to refine an OCR prog I made to read the layout of a certain image that I am using. Right now, I would like my OCR prog to recognise only digits 0-9. I tried to follow the solution from the question: Limit characters tesseract is looking for But I got stuck in the part where I have to call tesseract as: tesseract input.tif output nobatch letters where does this go? 回答1: I posted some things about tesseract some time ago in SO: see Tesseract OCR Library - Learning Font. There is

问题 So, from what I can begin.. I am working with OCR. The script works pretty well for what I need. It detects the words with an accuracy which for me is ok. This is the result: 100% accuracy with attached image. from PIL import Image import pyocr.builders import os os.putenv("TESSDATA_PREFIX", "C:\\Program Files (x86)\\Tesseract-OCR") tools = pyocr.get_available_tools() tool = tools[0] langs = tool.get_available_languages() lang = langs[0] #eng file = "test.png" txt = tool.image_to_string(Image

问题 So I am trying to extract text from image. And as the quality and size of image is not good, it is giving inaccurate results. I tried few enhancements and other things with PIL but that is only worsening the quality of image. Can someone suggest some enhancement in image to get better results. Few Examples of images: 回答1: In the provided example of image the text is visually of quite good quality, so the question is how it comes that OCR gives inaccurate results? To illustrate the conclusions

问题 Using OpenCV (python) I am trying to remove the section of image which is above the border line (white area in this sample image where ORIGINAL is writtn) in the image shown below Using horizontal and vertical kernels I am able to draw the wireframe, however that does not work many times because many times due to scanning quality few horizontal or vertical lines appear outside the wireframe which causes wrong contour detection. In this image also you can see on top right there is noise which

问题 I'm studying android using NDK with opencv. I success using ndk. So I get usable data ( I mean the data was done by canny.) When I use Tesseract, Data file not found at /storage/emulated/0/tesseract/tessdata/eng.traineddata This Error is occured. I already checked adroid/app/src/main/assets/tessdata/eng.traineddata there are the traineddata.... I don't know why I get an error there. plz... help me please... public class ocrActivity extends AppCompatActivity { private static final String TAG =

问题 I am using Apache Tika on Windows 10, jre 1.8.0_181, and I've imported Tika using Maven with the following dependencies: <dependencies> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>3.8.1</version> <scope>test</scope> </dependency> <dependency> <groupId>org.apache.tika</groupId> <artifactId>tika-parsers</artifactId> <version>1.21</version> </dependency> </dependencies> I have the code below for performing OCR using Tesseract (which I have independently tested

问题 I want to use pytesseract Arabic And I have ara.traineddata in my system /usr/share/tesseract/tessdata/ path and i have already installed tesseract package This is my code: import pytesseract from PIL import Image pytesseract.image_to_string(Image.open('test_arabic.png'), config='', lang="ara") and i get this error: TesseractError Traceback (most recent call last) in ----> 1 pytesseract.image_to_string(Image.open('test_persian.png'), config='', lang="ara") ~/.local/lib/python3.8/site-packages

问题 I am trying to install tesseract-ocr to use within a docker container, but when I feed a request to my api, I still get an error saying "FileNotFoundError: [Errno 2] No such file or directory: 'tesseract': 'tesseract'" I'm trying to maybe add tesseract to my ENV $Path variable in the Dockerfile, but I'm unable to locate where this tesseract package is even installed. Below I've added my Dockerfile, any help would be appreciated. Thanks! FROM python:3.6-alpine RUN apk add --update --no-cache

问题 Pytesseract is not recognized. I have tried all fixes documented online, including adding Tesseract-OCR to my Path variables, incorporating the pytesseract.pytesseract.tesseract_cmd = r'C:\Program Files\Tesseract-OCR\tesseract.exe' command path in my script, uninstalling and reinstalling pytesseract and tesseract. 回答1: In the line 23 vpnbookpassword = pytesseract.image_to_string(pwdi) there you have mentioned pytesseract.image_to_string but you have imported image_to_string from pytesseract

问题 I made a Python script that does OCR, and then I recycled the script and made a web app using Flask. The web app and its libraries are in a virtualenv, but the app is using the Tesseract OCR that was installed in the OS (Windows). I've been testing it from the local server. Now it is time for deployment, and I don't know how to install Tesseract in the venv or if it is possible to install it on a server. I don't know if what I'm saying makes sense, but I'm very lost and I will really
