Why CIFAR-10 images are not displayed properly using matplotlib?

Question

From the training set I took a image(\'img\') of size (3,32,32). I have used plt.imshow(img.T). The image is not clear. Now changes I have to make to image(\'img\') to make it m

Answer 1

try using

import matplotlib.pyplot as plt
from scipy.misc import toimage
plt.imshow(toimage(img))

I am not 100% sure of how the code works, but I think that because the images are stored in floating point numpy arrays, the imshow() function has a difficult time mapping them to the right colors. By typecasting them to image using toimage() you convert them into proper image format that imshow() expects, i.e not an array but an image encoded as .png or .jpg.

This code works for me every time I want to display images in python.
