Spring 2018
We present a new algorithm to estimate depth of real-world scenes containing an object semi-submerged in water using a light field camera. Existing hand-held consumer light field cameras are well-suited for automated refocusing, depth detection in outdoor environment. However, when it comes to...

The file is a lecture given to graduate level students on the genetics of cataract, corneal dystrophies, keratoconus and the heritability of refractive error.

The recovery of 3D information from 2D images is a well-studied problem in computer vision, with many competing methods that can achieve highly accurate results. However, relatively little attention has been paid to the problem of 3D reconstruction in underwater environments. When cameras are...

A fundamental component of stereo vision is that of epipolar geometry. It shows that the corresponding point of a pixel in one image is restricted to a line in another image. When a refractive surface is introduced, such as in underwater imaging, this constraint no longer holds. Instead, the...
