Remove noise from an image with pytorch autograd engine. Loss function defined below uses L1 norm then uses L2 norm.
Remove the noise from image (I), smooth the image, with pytorch library.
number of iterations = 3000
learning rate = 1
alpha (regularizer) = 2
Original Image (I):
Smoothed image with L1 norm (J):
Smoothed image with L2 norm (J):
