Matplotlib

This is a popular Python package for plotting and displaying data and images. To use in Python, the scripts is as follows:

import matplotlib.pyplot as plt 

If we want to plot inside Jupyter notebook, add the following command:

%matplotlib inline 

An example function to display an image is as follows:

def plot_img(input_image): 
    """ 
    Takes in image 
    Plots image using matplotlib
    """ 
    plt.figure(figsize=(12,8))
    
    # change color channels order for matplotlib 
    plt.imshow(input_image)

    # For easier view, turn off axis around image 
    plt.axis('off')
    plt.show()
