Transform Coding for Point Clouds Using a Gaussian Process Model.
IEEE Transactions on Image Processing(2017)
摘要
We propose using stationary Gaussian processes (GPs) to model the statistics of the signal on points in a point cloud, which can be considered samples of a GP at the positions of the points. Furthermore, we propose using Gaussian process transforms (GPTs), which are Karhunen-Loève transforms of the GP, as the basis of transform coding of the signal. Focusing on colored 3D point clouds, we propose ...
