Example-Based Super-Resolution for Point-Cloud Video
Diogo Caetano Garcia, Tiago A. da Fonseca, Ricardo Lopes de Queiroz · 2018
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 lowpass versions of the point-cloud, for a projection-based distortion metric [1], [2].
