Image Decimation – Icarus

Topic: Image decimation is the reverse of image interpolation. It is a very simple routine that takes an $an1*bn2$ image, where $a,b>1$ and resizes into a $n_1*n_2$ one, thus reducing its dimensions.

Exercise: Create a Python script file and perform the following tasks:

Import OpenCV and NumPy libraries.
Create a function that takes as input an image and a decimation factor and performs image decimation. Then, return the resized image. You can add any extra parameters you desire.
Read an image.
Apply image decimation to the image.
Finally, display the resized image.
