tesseract

问题 I'm currently writing an Android application which needs to use OCR within it. To achieve this I am using Tesseract in conjunction with the tesseract-android-tools project. I have managed to get the Tesseract API to initialize and need to use the following setImage function: void com.googlecode.tesseract.android.TessBaseAPI.setImage(byte[] imagedata, int width, int height, int bpp, int bpl) What I am struggling with is how to get the correct values for bpp (bytes per pixel) and bpl (bytes per

问题 I'm working on a project about recognizing moroccan license plates which look like this image : Moroccan License Plate Please how can I use OpenCV to cut the license plate out and Tesseract to read the numbers and arabic letter in the middle. I have looked into this research paper : https://www.researchgate.net/publication/323808469_Moroccan_License_Plate_recognition_using_a_hybrid_method_and_license_plate_features I have installed OpenCV and Tesseract for python in Windows 10. When I run the

问题 I am trying to get the coordinates or positions of text character from an Image using Tesseract. I want to know the exact pixel position, so that i can click that text using some other tool. Edit : import pytesseract from pytesseract import pytesseract import PIL from PIL import Image import cv2 import csv img = 'E:\\OCR-DATA\\sample.jpg' imge = Image.open(img) data=pytesseract.image_to_string(imge,lang='eng',boxes=True,config='hocr') print(data) data contains recognized text with box

问题 I'm trying to use Python to extract data from Tesseract's hocr output file. We're limited to tesseact version 3.04, so no image_to_data function or tsv output is available. I have been able to do it with beautifulsoup and in R, but that's neither are available in the environment in which it needs to be deployed. I am just trying to extract the word and confidence "x_wconf." An example output file is below, for which I'd be happy to just return lists of [90, 87, 89, 89] and ['the', '(quick)',

问题 I use Tesseract OCR to to extract meter reading... tesseract needs to recognize right white background and black numbers.. I tried to threshold image src := cvLoadImage(filename,CV_LOAD_IMAGE_GRAYSCALE); dst := cvCreateImage(cvGetSize(src), IPL_DEPTH_8U, 1); cvThreshold(src, dst, 50, 250, CV_THRESH_BINARY); but i didn't get the right result.. what should I do? I use deplhi6 with Delphi-OpenCV https://github.com/Laex/Delphi-OpenCV 回答1: You can treat this image as follows: for jy:= 0 to bm

问题 I would like to batch OCR about 5800 PDF (consisting each between 2 to 6 pages from my last question here) with open source command line tools on a Mac. The main propose of this adventure is that I want to retrieve as reliable as I can names (surnames most importantly) from the text of all these PDF . Here is an example how an issue looks like. At this point, I do not know exactly how to proceed. What would you do? I had in mind to first convert all multipage PDF to a single page image as

问题 Have someone configured Tesseract c++ source-code successfully? It has 32 stars, but I am stuck to even run it as it is While I am trying to setup the source code of Tesseract in my visual studio, it is giving errors in obj files, how can I edit those files, its not making any sense to me. If I do not do that then what different I should do to run it successfully at my environment (I have same specs as required by the github) 1.Error LNK2019 unresolved external symbol _l_dnaDiffAdjValues

问题 I am using Tess4j 3.0.0 with Tesseract 3.04 in my java Application. In my application I've created a service for OCR which implements Runnable. Application is deployed in Centos 6 below code is in Service. Tesseract1 instance = new Tesseract1(); result = instance.doOCR("pathtodocument/abc.pdf"); I start a thread of OCR service from Document Upload Service on request from user and process the text data from PDF. When I test the code for single request it works perfect. Problem is : When I send

问题 I am trying to use pytesseract on Jupyter Notebook. Windows 10 x64 Running Jupyter Notebook (Anaconda3, Python 3.6.1) with administrative privilege The work directory containing TIFF file is in different drive (Z:) When I run the following code: try: import Image except ImportError: from PIL import Image import pytesseract pytesseract.pytesseract.tesseract_cmd = 'C:\\Program Files (x86)\\Tesseract-OCR\\tesseract.exe' tessdata_dir_config = '--tessdata-dir "C:\\Program Files (x86)\\Tesseract

问题 I am using tesseract ocr in my app. In order to use tesseract i need to use several language files that are located at a directory called - 'tessdata'. This is my method code: public String detectText(Bitmap bitmap) { TessBaseAPI tessBaseAPI = new TessBaseAPI(); String DATA_PATH = Environment.getRootDirectory().getPath() + "/tessdata/"; tessBaseAPI.setDebug(true); tessBaseAPI.init(DATA_PATH, "eng"); //Init the Tess with the trained data file, with english language tessBaseAPI.setImage(bitmap)
