This should be a standard part of numpy
, perhaps numpy.pad(pad_width, mode='remove')
, but it’s not:
pad_width = [10, 30]
print("shape original:", im.shape)
im1 = np.pad(im, pad_width, mode="constant", constant_values=1)
print("shape padded:", im1.shape)
im3 = ps.tools.unpad(im1, pad_width)
print("shape new unpad:", im3.shape)
fig, ax = plt.subplots(1, 3, figsize=[8, 4])
ax[0].imshow(im)
ax[1].imshow(im1)
ax[2].imshow(im3)
ax[0].set_title('image')
ax[1].set_title('pad added')
ax[2].set_title('pad removed');
