What is the pyplot.imshow() method?

Matplotlib is a package in Python that is primarily used for plotting. It works in a way that emulates MATLAB. However, it can also be used to display images on the screen with the help of pyplot.im.show().

Code

The following image will be loaded in the examples below:

educative.png
educative.png

Using pyplot.im.show() with the default parameters

# Importing dependancies

import matplotlib.pyplot as pyplot

import matplotlib.image as mpimg



# loading the image

image = mpimg.imread("educative.png")

# displaying the image

pyplot.imshow(image)

pyplot.show()
Output of the above code
Output of the above code

Using pyplot.im.show() to convert an image to gray-scale

# importing the dependencies

import matplotlib.pyplot as pyplot

import matplotlib.image as mpimg



# loading the image

image = mpimg.imread("educative.png")

img = image[:,:,0]

# cmap = grey sets the image to grayscale

# Interpolation calculates what the color or value of a pixel “should” be, according 

# to different mathematical schemes. Setting it to bicubic means that

# the image will get blurred instead of getting pixelated

pyplot.imshow(img, cmap = "gray", interpolation = 'BICUBIC')

# We dont want the axis values that were displayed in the previous example.

pyplot.axis("off")

pyplot.show()
