+To blend 2 images, we can first start by creating a Gaussian/Laplacian stack. This is similar to a Gaussian stack, except that at each level, we don't need to downsample. The easiest way to achieve this is to have a function that takes in an array of images, and for each level, append one image to a list and recurse on the last (latest added) element of the list. In the end, a 3D (4D if using RGB images) array will be returned that is a collection of all the images in the stack:
