Matplotlib is a library in Python and it is numerical - mathematical extension for NumPy library. Pyplot is a state-based interface to a Matplotlib module which provides a MATLAB-like interface.
The imread() function in pyplot module of matplotlib library is used to read an image from a file into an array.

matplotlib.pyplot.imread() Function:
Syntax: matplotlib.pyplot.imread(fname, format=None) Parameters: This method accepts the following parameters.Below examples illustrate the matplotlib.pyplot.imread() function in matplotlib.pyplot: Example #1:Returns: This method return the following.
- fname : This parameter is the image file to read.
- format: This parameter is the image file format assumed for reading the data.
- imagedata : This returns the image data
