Let’s see how to build a form parser using Tesseract OCR, OpenCV, and Python. We will use feature-based Image alignment technique to extract specific information based on coordinate location.
OCR in short Optical Character Recognition or optical character reader is an essential part of data mining, which mainly deals with typed, handwritten, or printed documents. Every image in the world contains some information. In this post I will explain you detailed code for pytesseract (python wrapper of tesseract) image to string operation.
Flask is a very important web framework in python to create web applications, APIs, Machine Learning applications, etc. In my last few post, I discussed web application development using Django. Flask framework is more explicit and easier to learn than the Django framework. Flask is built on top of the WSGI(Web Server Gateway Interface) toolkit and Jinja2 template engine.
