Subjective Quality Assessment of V-PCC-Compressed Dynamic Point Clouds Degraded...
Dumic, Emil; Cruz, Luís A. da SilvaThis article describes an empirical exploration on the effect of information loss affecting compressed representations of dynamic point clouds on the subjective quality of the reconstructed point clouds. The study involved compressing a set of test dynamic point clouds using the MPEG V-PCC (Video-based Point Cloud Compression) codec at 5 different levels of compression and applying simulated packet losses with ...
Point Cloud Coding Solutions, Subjective Assessment and Objective Measures: A C...
Dumic, Emil; Cruz, Luís A. da SilvaThis paper presents a summary of recent progress in compression, subjective assessment and objective quality measures of point cloud representations of three dimensional visual information. Different existing point cloud datasets, as well as discusses the protocols that have been proposed to evaluate the subjective quality of point cloud data. Several geometry and attribute point cloud data objective quality me...
Point cloud quality evaluation: Towards a definition for test conditions
Cruz, Luís; Dumic, Emil; Alexiou, Evangelos; Prazeres, João; Duarte, Rafael; Pereira, Manuela; Pinheiro, Antonio M. G.; Ebrahimi, TouradjRecently stakeholders in the area of multimedia representation and transmission have been looking at plenoptic technologies to improve immersive experience. Among these technologies, point clouds denote a volumetric information representation format with important applications in the entertainment, automotive and geographical mapping industries. There is some consensus that state-of-the-art solutions for effici...
