Document-Boundary-Detection

I've translated python script in c#, I've used OpenCVSharp. I've decided to remove NumPy dependency, I've replaced it with native linq.

Original scripts are here:

4-point Perspective Transform

A common task in computer vision and image processing is to perform a 4-point perspective transform of a ROI in an image and obtain a top-down, "birds eye view" of the ROI. The perspective module takes care of this for you. A real-world example of applying a 4-point perspective transform can be bound in this blog on on building a kick-ass mobile document scanner.

Example

Document Boundary & Canny Edge Detection using OpenCV

Used Simple OpenCV Library for Boundary and Edge Detection
The Algorithm is quite fast and does not require any training and works quite well with rectangle documents as it was meant for document boundry detection
Did not use Deep Learning Techniques as it was most computationally expensive and required good Dataset of images with Boundry label and would had been slow too
Sometimes simpler models are better than deep learning models
