scipy.ndimage is a submodule of SciPy which is mostly used for performing an image related operation
It is now deprecated we can not use the misc package on the latest version scipy.
If we want to show image and perform an operation on images then we can use
imageio package to write and read images with the following code.
import imageio
f=imageio.imread('img.jpg')
import matplotlib.pyplot as plt
plt.imshow(f)
plt.show()
#note you can upload your own images to show the image(img.jpg).
If we want to flip the images of the actual image using this then we can use flipud() of numpy
import numpy as np flip_ud_face = np.flipud(f) plt.imshow(flip_ud_face) plt.show()
Rotate the image at particular angle in scipy.import numpy as np from scipy import ndimage, misc s=ndimage.rotate(f, 45) plt.imshow(s) plt.show()Code to blur imageimport numpy as np from scipy import ndimage, misc #s=ndimage.rotate(f, 45) s=ndimage.gaussian_filter(f, sigma=3) plt.imshow(s) plt.show()http://scipy-lectures.org/advanced/image_processing/
