Tesseract.js is a pure Javascript port of the popular Tesseract OCR engine. This library supports more than 100 languages, automatic text orientation and script detection, a simple interface for reading paragraph, word, and character bounding boxes. Tesseract.js can run either in a browser and on a server with NodeJS OCR in the browser with Tesseract.js. Optical character recognition or optical character reader (OCR) is the process of converting images of text into machine-encoded text. For example, you can take a picture of a book page and then run it through an OCR software to extract the text. In this blog post, we are going to use the Tesseract OCR library An OCR demo application using tesseract.js and html with smartphone camera. - quiye/oc 4. 5. ionic start ocrexample blank. cd ocrexample. npm install tesseract.js @ionic-native/camera @ngx-progressbar/core. npm install @types/tesseract.js --save-dev. ionic cordova plugin add cordova-plugin-camera. Now we need to hook up everything inside our src/app/app.module.ts so we can later use the progress bar and camera therefore change it. 2. I'm using Tesseract OCR 3.01 in my iOS application, it shows 90% accuracy for my data when I pick an image from my phone's library. But if I use the same image from the camera, it is showing jumbled letters. I followed this tutorial, kindly guide me if something can be done to make sure it works from camera as it works for gallery images

Object Tracking in Vision: Interesting changes coming to Vision in iOS at WWDC 2018. There are lot of improvements in object tracking and custom model training In your new project, we will go right ahead and install tesseract.js and create a provider. If you don't know what a provider is, it is a service class, where we will implement our OCR-logic, to use later anywhere throughout the app. cd tesseractApp npm install tesseract.js --save ionic g provider OcrProvide

Step #2 - glfx.js, JCrop. glfx.js was used for image effects (sharpening, contrast, etc.). Cropping functionality (with touch support) is provided by jQuery plugin Jcrop. Step #3 - Tesseract.js. Tesseract.js was used for OCR (Optical Character Recognition). It is a javascript version of the Tesseract Open Source OCR Engine Tesseract.js OCR. Contribute to bensonruan/Tesseract-OCR development by creating an account on GitHub We could get a scanned image of a book, and use OCR tech to read the image, and output text in a format we can use on a machine. This could drastically improve our productivity, and it avoids duplicate manual entry. In this tutorial, I'll show you how to use Tesseract.js to build an OCR web application. Let's jump straight into the code In this first episode of interesting JavaScript Library series, I have talked about Tesseract.js which can be used for optical character recognition or in sh.. If the image is distorted by camera perspective, detection is horrible. So be prepared to offer some additional UI to dewarp the image before OCR (maybe using something like imgwarp-js ). Tesseract can detect words from the following sources (from the README)
