Document_Scanner

The process was accomplished using OpenCV and can be broken down into just four simple steps:

1. Detect edges.
2. Use the edges to find the contour (outline) representing the paper to be scanned.
3. Apply a perspective transform to obtain the top-down view of the document, a 90-degree view of the image.
4. Apply thresholding to get a nice, clean black and white feel to the piece of paper.
