This python script will allow us to change perspective of an image.
sudo apt-get install python3
sudo apt-get install python3-pip
pip3 install numpy
pip3 install opencv-python
sudo apt-get install python3-tk
User selects an input image and the script changes its perspective and displays it.
(Note The positions of any 4 points (no 3 of them should be collinear) on the original image and the positions where they would be present after the transformation should be specified in the code.
