Example-based super-resolution for point-cloud video
We propose a mixed-resolution point-cloud representation and an example-based
super-resolution framework, from which several processing tools can be derived,
such as compression, denoising and error concealment. By inferring the
high-frequency content of low-resolution frames based on the similarities
between adjacent full-resolution frames, the proposed framework achieves an
average 1.18 dB gain over low-pass versions of the point-cloud, for a
projection-based distortion metric[1-2].Comment: This paper was submitted to ICIP-2018 and its copyright may be
