Abstract:
A moving object in a five-dimensional (5-D) light
field video (LFV) can be selectively enhanced using the depth
and the velocity of the object. In this paper, a 5-D depth-velocity
(DV) filter is proposed to enhance multiple moving objects at
different depths and with different velocities in an LFV. The
5-D DV filter is designed as a cascade of an infinite-extent
impulse response multi-depth filter and a finite-extent impulse
response multi-velocity filter. Experimental results obtained with
numerically generated and real LFVs indicate that more than 15
dB improvement in signal-to-interference ratio can be achieved
with the proposed 5-D multi DV filter compared to previously
proposed multi depth-only filters.
