How to read text from images on Windows
There are all kinds of reasons why you might want to extract text out of images. Maybe you've taken photos of restaurant bills and you want to make a record of what you've eaten; or perhaps you've got a bunch of screenshots that you need to get product names out of; or you could have scanned in some important documents that need sorting. Whatever the reason, Windows comes with built-in tools for picking out text from image files (technically known as OCR, or Optical Character Recognition)--in fact, there are several different ways, so you can pick the one that suits you best. Here's how to get started, assuming you already have your images saved somewhere. The Snipping Tool is the easiest way to extract text from images on Windows.
Making History Readable
Banerjee, Bipasha, Goyne, Jennifer, Ingram, William A.
The Virginia Tech University Libraries (VTUL) Digital Library Platform (DLP) hosts digital collections that offer our users access to a wide variety of documents of historical and cultural importance. These collections are not only of academic importance but also provide our users with a glance at local historical events. Our DLP contains collections comprising digital objects featuring complex layouts, faded imagery, and hard-to-read handwritten text, which makes providing online access to these materials challenging. To address these issues, we integrate AI into our DLP workflow and convert the text in the digital objects into a machine-readable format. To enhance the user experience with our historical collections, we use custom AI agents for handwriting recognition, text extraction, and large language models (LLMs) for summarization. This poster highlights three collections focusing on handwritten letters, newspapers, and digitized topographic maps. We discuss the challenges with each collection and detail our approaches to address them. Our proposed methods aim to enhance the user experience by making the contents in these collections easier to search and navigate.

Invisible Threats: Backdoor Attack in OCR Systems
Conti, Mauro, Farronato, Nicola, Koffas, Stefanos, Pajola, Luca, Picek, Stjepan
Optical Character Recognition (OCR) is a widely used tool to extract text from scanned documents. Today, the state-of-the-art is achieved by exploiting deep neural networks. However, the cost of this performance is paid at the price of system vulnerability. For instance, in backdoor attacks, attackers compromise the training phase by inserting a backdoor in the victim's model that will be activated at testing time by specific patterns while leaving the overall model performance intact. This work proposes a backdoor attack for OCR resulting in the injection of non-readable characters from malicious input images. This simple but effective attack exposes the state-of-the-art OCR weakness, making the extracted text correct to human eyes but simultaneously unusable for the NLP application that uses OCR as a preprocessing step. Experimental results show that the attacked models successfully output non-readable characters for around 90% of the poisoned instances without harming their performance for the remaining instances.

💣Notes to Self: Optical Character Recognition or Optical Character Reader (OCR)
Optical character recognition (OCR) is a technology that allows computers to recognize and extract text from images, such as scanned documents, photographs, bills, etc. The process involves analyzing the image and identifying the individual characters within it and then converting those characters into machine-readable text. OCR software can be used to automate tasks such as document scanning, business automation, and accessibility technology. OCR software uses complex algorithms and pattern recognition techniques to identify and extract text. OCR technology has evolved over time and now it has the ability to recognize text in multiple languages and different fonts.
ChatGPT Meets Voice: Say goodbye to typing and Hello to VoiceGPT 🤖🔊
If you're a fan of recently published AI chatbots like OpenAI's ChatGPT, you know how useful they can be for answering questions, generating text, and performing a variety of other tasks. But have you ever wished you could have a more natural and seamless conversation with your AI assistant? Look no further, because VoiceGPT is here to revolutionize the way you interact with ChatGPT. VoiceGPT is a new Android app that builds on the already impressive capabilities of ChatGPT by adding a range of new features that make it even more powerful and user-friendly. With VoiceGPT, you can use your voice to input questions and commands and hear spoken responses, use OCR technology to extract text from images and have ChatGPT process it, and even choose from 67 different languages for input and output.
AMAZON MACHINE LEARNING
What is Amazon Web Services? Amazon Web Services or AWS is world's broadly adopted cloud platform . AWS provides with a number of useful cloud computing services that are very much reliable, scalable and cost efficient as they say. AWS provides services like storage, networking, remote computing, servers, email, mobile development and security . So now coming to Amazon machine learning, frankly means leveraging ML algorithms on cloud platforms like AWS .
Extract Text from Image
If your images deal with invoices, receipts, passports or driver's licenses, check out Nanonets pre-trained image to text extractors for free. Just select the appropriate extractor, upload the images, extract & export the text. Extracting text from an image can be a cumbersome process. Most people just retype the text or data from the image; but this is both time-consuming and inefficient when you have a lot of images to deal with. Image to text converters, often in-built as a sub-feature in image/document processing programs, offer a neat way to extract text from images.
Extract text from memes with Python, OpenCV and Tesseract OCR
Extracting text information from an image can serve different scopes. In our case, we needed to extract text to enhance the performance of our multi-modal sentiment classification model based on tweets accompanied by images. Since we found that the most common reaction pic that can be found on social media are formatted as MEMEs, we developed a pipeline to extract text from images formatted like that, and in this article, we'll present it. Currently (Nov 2020), the state of the art in text extraction through OCR methods is represented by Google Tesseract OCR, which is the most used open-source software to deal with this task. Tesseract is easy to install (following this link) and use in a python environment, through the pytesseract library.
Translating PDF documents using Amazon Translate and Amazon Textract
In 1993, the Portable Document Format or the PDF was born and released to the world. Since then, companies across various industries have been creating, scanning, and storing large volumes of documents in this digital format. These documents and the content within them are vital to supporting your business. Yet in many cases, the content is text-heavy and often written in a different language. This limits the flow of information and can directly influence your organization's business productivity and global expansion strategy.
Extracting custom entities from documents with Amazon Textract and Amazon Comprehend
Amazon Textract is a machine learning (ML) service that makes it easy to extract text and data from scanned documents. Textract goes beyond simple optical character recognition (OCR) to identify the contents of fields in forms and information stored in tables. This allows you to use Amazon Textract to instantly "read" virtually any type of document and accurately extract text and data without needing any manual effort or custom code. Amazon Textract has multiple applications in a variety of fields. For example, talent management companies can use Amazon Textract to automate the process of extracting a candidate's skill set.
