Document-Scanner

Python Script written with OpenCV to implement document scanner.

In this scenario we make use of Perspective transform to get the top-down view of the image in a plane.

Four-Point Transform is applied to approximate Region of Interest and filter selected area from the image provided. Here we assume that the document will be one with a rectangular contour, and thus apply transformations accordingly.
