Point Cloud Geometry Scalable Coding Using a Resolution and Quality-Conditioned Latents Probability Estimator

open access: yesIEEE Access
In the current age, users consume multimedia content in very heterogeneous scenarios in terms of network, hardware, and display capabilities. A naive solution to this problem is to encode multiple independent streams, each covering a different possible ...

Learning residual coding for point clouds [PDF]

open access: yesApplications of Digital Image Processing XLIV, 2021
Recent advancements in acquisition of three-dimensional models have been increasingly drawing attention to imaging modalities based on the plenoptic representations, such as light fields and point clouds. Since point cloud models can often contain millions of points, each including both geometric positions and associated attributes, efficient ...

Point Cloud Object Reconstruction Based on Improved Implicit Function [PDF]

open access: yesJisuanji gongcheng, 2023
Using an implicit function to reconstruct objects from unstructured point clouds is not limited by topology and resolution, but there are some problems, such as inaccurate structure of reconstructed objects and lack of local details.

Point cloud saliency detection via local sparse coding

open access: yesDyna, 2019
The human visual system (HVS) can process large quantities of visual information instantly. Visual saliency perception is the process of locating and identifying regions with a high degree of saliency from a visual standpoint. Mesh saliency detection has

Towards robustness and generalization of point cloud representation: A geometry coding method and a large-scale object-level dataset

open access: yesComputational Visual Media, 2023
Robustness and generalization are two challenging problems for learning point cloud representation. To tackle these problems, we first design a novel geometry coding model, which can effectively use an invariant eigengraph to group points with similar ...

GPCGC: A Green Point Cloud Geometry Coding Method

open access: yes2023 IEEE International Conference on Image Processing (ICIP), 2023
A low-complexity point cloud compression method called the Green Point Cloud Geometry Codec (GPCGC), is proposed to encode the 3D spatial coordinates of static point clouds efficiently. GPCGC consists of two modules. In the first module, point coordinates of input point clouds are hierarchically organized into an octree structure.
