Depth Refocusing

Here, I shifted all the images based on their c*(u, v) values, where c is a fixed value and the u, v values are the u, v coordinates of each image. Then I averaged the shifted images, and was able to refocus on different depths by changing the c value, as seen in the gifs below.

Aperture Adjustment

Here, I changed the aperture by including only photos that had coordinates within a specific radius. The larger the radius, the more photos were averaged. This simulated a higher aperture, and a smaller depth of field. The inverse is true for a smaller radius; there were fewer photos, simulating a smaller aperture, and a larger depth of field.

Summary

I learned that we can recreate depth by combining photos from different coordinates, and shifting them to the correct degree. It was cool to see how different the depth of the tarot cards and bracelet were. I used c values from -4 to 2 for the bracelet, and -6 to 8 for the tarot cards. I had expected the ranges to be the same.
