## What is this ?

+
The script takes an image as input and then scans the document from the image by applying few image processing techniques and gives the output image with scanned effect

## How does it do this?
9
+
Initially we need to resize the images so OpenCV can handle it and then the following functions are applied
10
+
1) Guassian Blur to smoothen image.
11
+
2) Canny Edges to detect the edges.
12
+
3) Find contours and boundary of the page
13
+
4) Map the end points of contours to 800 * 800 window
14
+
5) Apply perspective trasform to get scanned or bird eye view of the image.
