Superresolution with Plenoptic Camera 2.0

Excellent paper

 This work is based on the plenoptic 2.0 camera, which captures an array of real images focused on the object. We show that this very fact makes it possible to use the camera data with super-resolution techniques, which enables the focused plenoptic camera to achieve high spatial resolution. We derive the conditions under which the focused plenoptic camera can capture radiance data suitable for super resolution. We develop an algorithm for super resolving those images. Experimental results are presented that show a 9× increase in spatial resolution compared to the basic plenoptic 2.0 rendering approach.
