Document scanning is the process of converting physical documents into digital form. This can be done by taking an image with a scanner or a phone camera. In this tutorial we'll discuss how to do this effectively using computer vision and image processing techniques.
In today's computer age, there is hardly any physical paperwork required. Nevertheless, in the rare cases where physical documents are still required, it is necessary for us to have a medium to convert them into digital documents. Thankfully, we no longer need traditional hardware scanners as they take up a lot of space and are slow to process documents.
There are many software solutions and apps to do this. With the power of computer vision, the process of going from a physical document to a scanned document is not much different from pointing a camera at a document and clicking a picture. Speed and ease of use are the main advantages of such solutions, and they are available for both computers and mobile devices.
Let's see how to create a simple OpenCV document scanner using classic computer vision techniques &
