Reading the text value or number from an image using node.js

I want to read a number from an image using Node.js.

I am parsing the image using canvas and then reading the image but it gives me the binary data for image but I need the number value that image contains.

Try:

npm install tesseract.js

Then include file in node.js

var Tesseract = require('tesseract.js');

Then

Tesseract.recognize(
  'https://tesseract.projectnaptha.com/img/eng_bw.png',
  'eng',
  { logger: m => console.log(m) }
).then(({ data: { text } }) => {
  console.log(text);
})

Well, obviously you can't just read data off the image and get the text you need.

You need to interpret the image with some OCR (Optical character recognition) software.

What I could suggest if you are keen on using NodeJS is the node-tesseract module. Make sure to do as the Installation guide says because you also need to install the tesseract-ocr software as well as the module.
