Light-DPCVR: Assessing the Impact of Lighting on Dynamic Point Cloud Quality and User Behavior in XR

This repository contains all the stimuli and resulting data of our subjective experiment to build the Light-DPCVR dataset. It includes: Seq/ SRC/: The 5 pre-processed source point cloud sequences we selected from the UVG-VPC dataset HRC/: 3 distorted version of each source, compressed with V-PCC (geometry, color, normals) UserLogs XX_ACR.csv: the quality ratings given to all stimuli by observer XX XX_ACR_Eyetracking_YY.csv: The eyetracking data of observer XX collected while they were viewing their YYth stimulus XX_ACR_HeadTracking_YY.csv: The position and head orientation of observer XX viewing their YYth stimulus Saliency: Voxelized point cloud sequence with saliency as color for all stimuli Stimuli are all sources (5) and compressed versions (3x5), all rendered and viewed under different light settings (4) -> Total of (5+5x3)x4 = 80 stimuli Light settings are: - LØ: Only raw color of the point clouds, without unlit rendering - L0: 50% ambient light and 80% directional light (x:0°;y:12°) - L30: 50% ambient light and 80% directional light (x:30°;y:12°) - L60: 50% ambient light and 80% directional light (x:60°;y:12°)
