+ +# Developer - Winter of Code 2020 +* **Name:** Abhinav Chauhan +* **Organisation:** DSC - NSEC +* **Project:** [DocScanner](https://github.com/dscnsec/DocScanner.git) + +## Language Used +* Python + +## Library Used +* OpenCV +* Numpy + +## There are Following Steps:- +## Reading image using OpenCV +Original Image + +## Image Preprocessing +* Converting orginal image to grey color +* Converting grey image to blurred image using Gaussian Blur +* Detecting edges using canny edge detector +* dilation and erosion of inage for better contour detection. +Preprocessed Image + + +## Contour Detection +* He we handle all the contour Detected and keep only the one with the greatest contour area. +* After getting that contour we draw a bounding box around it for visualisation and keep the coordinates of the corners of the required contour detected. +Contour corner points + +## Reorder coordinates +* This is the main function that resolves the issue posted in the repo. i.e to get corret order of the corner points of the contour detected. +* Arranging the corner coordinates in the correct order for Wrapping function at realtime using simple numpy library and basic arithmetic functions. + +## Wrapping the Image +* In this step we wrap the image with the ordered points i.e. (0,0) (width, 0) (0, height) and (width, height) which we got from the reorder function. + +## Result Image +* Here we diplay the the final scanned image. +Scanned output image + +## Link To My Pull Request +https://github.com/dscnsec/DocScanner/pull/5 + +## Future Scope +* Working in the project of DocScanner not only we got more application in machine learning but we also got more intents towards different arean of computer vision. + +## Overall Experience +* It was great exprience for me to got into Open Source culture through this great program and I would love to encorage more students to do this program in future.
