This python script will allow us to linear blend two images depending on given alpha - the amount of blending.

sudo apt-get install python3

sudo apt-get install python3-pip

pip3 install opencv-python

sudo apt-get install python3-tk

A dialog box appears with option to enter alpha (the degree of blending, 0 to 1), and select images 1 and 2. Then clicking proceed will display the blended image and stores it in the current folder.
