Abstract:
In recent years, there has been an increase in the popularity of Light Field
(LF) imaging technology with the increase in availability of LF camera
devices such as the Lytro, as well as an increase in the use of LF camera
arrays [5]. However, both camera arrays and LF cameras can create views
that exhibit colour discrepancies, and previous work has already tackled
similar issues when data is captured using the Lytro camera [4] or multiview
camera systems [3]. In [4], an L2 based colour transfer method
is applied in an iterative approach to recolour the views of a Lytro light
field to correct the colour fading that occurs on outer views of the LF.
This method was based on earlier L2 based methods proposed by Grogan
et al.[1, 2]. In this paper, we propose to combine similar aspects of the
L2 based cost function proposed in [1] with some of the cost function
constraints proposed in [2], and propose a new propagation scheme so
that this L2 based framework can be extended to colour correcting LF
arrays. We also take advantage of a colour chart captured in the scene to
not only ensure that colours are consistent across the LF, but also match
the ground truth colour chart.
