Enhancing Moving Objects in light field videos using 5-D IIR adaptive depth-velocity filters

Abstract

The spectrum of an object moving in 5-D light field videos (also known as plenoptic videos) with constant velocity and at non-constant depth is analyzed. Based on this analysis, a novel 5-D IIR adaptive depth-velocity filter is proposed for enhancing such objects. The time-variant coefficients of the proposed 5-D IIR adaptive depth-velocity filter are derived in closed form. Numerical simulation results confirm the effectiveness of the proposed filter compared to 3-D IIR adaptive velocity filters and 4-D IIR adaptive depth filters.
