Light field compression by superpixel based filtering and pseudo-temporal reordering

Abstract:

In this paper we have addressed the topic of an evolutionary integration of light fields into standard image/video processing chains by pre-processing light fields with superpixel-based and structurally adaptive Gaussian pre-filters and circular pseudo-temporal sequencing to feed them into an HEVC-codec with low-delay predictive coding configuration. We could show significant bit rate reductions of up to 27% compared to pseudo-temporal sequencing without pre-processing. The paper includes experimental results showing that not only the perceived visual quality, but also the cornucopia of post-processing options is preserved.
