Last week I start reading and studying about “Image Processing”, in some point I was reading about converting an image to Array of numbers, and re-converting that Array back to an Image, at that moment popped into my mind what if we just generate an Array with random numbers and then show it as an Image.

In this article we will write a first simple Function to generate a random numbers presenting the three main color Red, Blue and Green; then storing the numbers in an Array then using matplotlib library to display the Image.

Our Tools: In this post we will use the following:
1. Jupyter-NoteBook.
2. numpy.
3. random.
4. matplotlib.
5. PIL or Pillow.

Coding I am user Jupyter NoteBook on samsung Tab S4. First we will do all imports we need as:
from PIL import Image
import numpy as np, matplotlib.pyplot as plt
import random
%matplotlib inline

Now, we will write a Function called rand_color, we will run a nested for loop to generate the Row and Column (width and height) and in/for each row we will generate thee numbers of colors range(0,255) as one pixel and storing them in an array, then we display the Array using:
Image.fromarray and plt.imshow(). Here is the Code ..

Run No.1	Run No.2
Run No.3	Run No.4

The above is just 25×25 image with random color pixels, this is the first function using default random, in coming posts we will use some Math variables [such: log,sin], constants [such: pi, golden ratio] to see if we can get a pattern from random.
