问题 I use a code to locate text boxes and create a rectangle around them. This allows me to rebuild the grid around the table structure in the image. However, even if the text box detection works very well, if I try to define the characters present in each rectangle, pytesseract does not identify them well and does not allow to find the original text. Here is my Python code : import os import cv2 import imutils import argparse import numpy as np import pytesseract # This only works if there's

问题 I already can use the textract but with JPEG files. I would like to use it with PDF files. I have the code bellow: import boto3 # Document documentName = "Path to document in JPEG" # Read document content with open(documentName, 'rb') as document: imageBytes = bytearray(document.read()) # Amazon Textract client textract = boto3.client('textract') documentText = "" # Call Amazon Textract response = textract.detect_document_text(Document={'Bytes': imageBytes}) #print(response) # Print detected

问题 It is required to recognize text from forms with boxes given for each character input. I have tried using bounding box for each input and cropping that particular input, i.e I can get all the boxes for inputting in 'Name' field. But when I try to detect individual boxes in the group of boxes, I am not able to do so and the opencv returns only one contour for all the boxes. The file referred in the for loop is a file containing coordinates of the bounding box. The cropped_img is the image

问题 . I want to extract the ID attribute from an HTML file by using Notepad++ or Dreamweaver. Delete all other texts. For Eg: <div id="header" class="header-blue sticky"> <div id="header-message" class="alert alert-dismissible"> <form id="contact-form" class="custom-form" method="POST" action="https://www.google.com"> <input id="your-email" type="email" class="form-email" placeholder="Your Email"> I want to extract only ID attribute from HTML like this; id="header" id="header-message" id="contact

问题 I am having three image of pan card for testing skew of image using emgucv and c#. 1st image which is on top Detected 180 degree working properly. 2nd image which is in middle Detected 90 dgree should detected as 180 degree. 3rd image Detected 180 degree should detected as 90 degree. One observation I am having that i wanted to share here is when i crop unwanted part of image from up and down side of pan card using paint brush, it gives me expected result using below mention code. Now i
