Part 1

Part 1.1: Warmup

I picked two random pictures to sharpen: one of Machu Picchu and one of some trees. The tree photo turned out especially well. You can tell that the trunks are more defined.

Part 1.2: Hybrid Image

I took the gaussian of one image and the laplacian of another and layered them to form some hybrid images. If you look at them from far away, you will only be able to see the gaussian image. But, if you look at them up close, you will be able to see the laplacian.

My favorite was the trumpbama result. You can really identify Obama up close and trump from far away.

Part 1.3: Laplacian Stack

To create the Laplacian stack, I repeadly convolved the image with the Gaussian, and subtracted each Gaussian from the one before it. Then, I just tack on the last Gaussian at the end.

Part 1.4: Multiresolution blending

By applying a mask to each layer of the laplacian stacks, we can obtain a blend of two images.
