Document Scanner An interactive document scanner built in Python using OpenCV. The scanner takes a poorly scanned image, finds the corners of the document, applies the perspective transformation to get a top-down view of the document, sharpens the image, and applies an adaptive color threshold to clean up the image document-scanner. A document scanner built using OpenCV + Python. I highly recommend to see my blog post for better understanding: http://vipulsharma20.blogspot.on.

Welcome to another OpenCV with Python tutorial, in this tutorial we're going to cover a fairly basic version of object recognition. The idea here is to find identical regions of an image that match a template we provide, giving a certain threshold. For exact object matches, with exact lighting/scale/angle, this can work great. An example where these conditions are usually met is just about any.
