python-scipyHow do I rotate an image using Python and SciPy?

To rotate an image using Python and SciPy, you can use the ndimage.rotate function. This function takes in an image array, an angle in degrees, and optionally an order of interpolation. The following example rotates an image 90 degrees clockwise:

from scipy import ndimage
import matplotlib.pyplot as plt

# Load the image
img = plt.imread('image.jpg')

# Rotate the image 90 degrees clockwise
rotated_img = ndimage.rotate(img, 90)

# Show the rotated image
plt.imshow(rotated_img)

Code explanation

• from scipy import ndimage: imports the ndimage module from scipy
• import matplotlib.pyplot as plt: imports the pyplot module from matplotlib
• img = plt.imread('image.jpg'): loads the image from the specified filename
• rotated_img = ndimage.rotate(img, 90): rotates the image by 90 degrees clockwise
• plt.imshow(rotated_img): displays the rotated image
