Portrait Bokeh Implementation on Faces using OpenCV and NumPy in Python

What it does?

1. Blurs everything except faces.
2. Gives you a choice to select which face you want in the foreground.

Why is it special?

Note: Thanks to @vishwesh5 for the hints to proceed with the 1st point below.

1. ROI generally works for only rectangles in OpenCV. This project can do for any shape.
2. It's cool!

Usage

1. Execute the program: python3 main.py <image_path> 9
2. Press Y when asked, if you don't want the face to be blurred. Else press N.
3. Output will be stored as blur.png in the same folder as the python file.

Example with Multiple Faces
