Hybrid Images 1.2

No Title

This one looks pretty realistic and if you zoom out enough you can see the real hybridization of images.

No Title

Same with this one!

No Title

Not this one though, with the jagged images and dissimlar patterns, it's hard to discern the images.

Brief Description of the Project

The purpose of part 2 of the project was to mess with various gradient computation algorithms and use them to develop a Poisson blend to insert features from one image into another image. I went about thisusing sparse matrices and Linear Least Squares Regressions as was recommended in the class. I struggled a lot with this particular project in terms of the matrix libraries and especially with the debugging and making the best use of the pictures to display the results. I think overall though, I was very impressed that I could pull off some of these results. Putting a graphic image of a boat into a real life picture of myself was pretty neat and I'm glad to be able to understand the regression and math behind computing such an image.

The Poisson Blending Problem

Simba and a Bear

A bad example of the blend, Simba becomes a little green and the jagged edges of the
mask make it very easy to tell it's unnaturally placed.

The Titanic in Crater Lake

Poisson blended, the water from this graphic blends well with the water from the lake.

Titanic pasted in crater Lake

Without any poisson and simply pasting the image, it doesn't look nearly as good.

Obama Biden Poisson Blend

Not great compared to the multi_res image blend because of the way the frequencies play out in letting us see different images.
