This document discusses lossy light field compression techniques. It introduces the plenoptic function and different light field representations like texture, depth maps, and point clouds. It then examines existing 2D and 3D image compression standards that can be applied to light fields, such as JPEG, H.264, and JPEG 2000. The document presents results comparing the performance of 2D JPEG 2000 and 3D JPEG 2000 compression on sample 8x8 camera array and Lytro Illum light field data, showing that 3D JPEG 2000 provides better compression at equivalent quality levels.
