tesseract

问题 We are cropping the pan card image by increasing the height by 20px for every iteration and then we are passing that image to tesseract to do ocr but we are getting noise with output.if you have better solution on Image processing or another libraries like cv2 then please help us. import pytesseract from PIL import Image, ImageEnhance, ImageFilter im = Image.open("image/testpan.jpg") width = im.size[0] height = im.size[1] print('width,height-->',width,height) yy='img' zz='.jpg' x=0 for j in

问题 I'm using the latest Tesseract OCR engine in R to extract text from a couple of images. It works pretty well and I'm happy with the results. The problem is that I don't want the whole text, just some part, but I don't know how to extract it. Code is this: library("tesseract") library("pdftools") library("magick") mypdfFile<-"C:/Users/.../fileName.pdf" mypngFile<-pdf_convert(mypdfFile, format="png", pages=1, dpi=600) myImage<-image_read("fileName_1.png") textFile<-ocr(myImage,engine =

问题 For my current ocr project I tried using tesserect using the the python cover pytesseract for converting images into text files. Up till now I was only passing well straight oriented images into my module at it was able to properly figure out text in that image. But now as I am passing rotated images it is not able recognize even a single word. So to get good result I need to pass images only with proper orientation. Now I want to know that is there any method to figure out the orientation of

问题 I have a Python app which words great via Localhost on my machine. I am trying to deploy it to Heroku. However it does not seem possible to accomplish this (I have spent approx 30 hours trying now). The problem is Tesseract OCR. I am using the pytesseract wrapper, and my code utilises this. However, no matter what I try, it does not seem to be possible to use pytesseract when it is uploaded to Heroku. Could anyone either suggest how to go about deploying a Hello World Tesseract OCR Python app

问题 I am having a hard time working with Tesseract, is there a way to improve the accuracy? How do I train it for myself, if needed? the only thing I am doing is reading the following characters, XYZ:-0123456789 that's it! The pictures always look that way. thanks! 回答1: The output of Tesseract 4.00alpha with your image is $ tesseract ICKcj.png - -l eng *: 4606 Y; 4809 Z; 698 Warning. Invalid resolution 0 dpi. Using 70 instead. Resample the picture to 50% and setting the dpi to 300: The output

问题 I've started a simple project in which it must get an image containing text with superscripts and then by using OCR (currently I'm using tesseract) it has to recognize the superscript characters + the normal ones. For example, we have a chemical equation such as Cl², but when I use the tesseract to recognize it, it gives me Cl2 (all in one line). So, what is the solution for this problem? Is there any other OCR API that has the ability to read superscripts? 回答1: Very good question that
