GScomp-QA: A Subjective Dataset for Quality Assessment of Compressed Gaussian Splatting
Pedro Martin, António Rodrigues, João Ascenso +1
Gaussian Splatting (GS) has emerged as an efficient representation for high-quality 3D reconstruction and novel view synthesis. However, its large model size poses challenges for s…
Structured Image-based Coding for Efficient Gaussian Splatting Compression
Pedro Martin, Antonio Rodrigues, Joao Ascenso +1
Gaussian Splatting (GS) has recently emerged as a state-of-the-art representation for radiance fields, combining real-time rendering with high visual fidelity. However, GS models r…
Evaluation of strategies for efficient rate-distortion NeRF streaming
Pedro Martin, António Rodrigues, João Ascenso +1
Neural Radiance Fields (NeRF) have revolutionized the field of 3D visual representation by enabling highly realistic and detailed scene reconstructions from a sparse set of images.…
Globally and Locally Optimized Pannini Projection for High FoV Rendering of 360-degree Images
Falah Jabar, Joao Ascenso, Maria Paula Queluz
To render a spherical (360 degree or omnidirectional) image on planar displays, a 2D image -- called as viewport -- must be obtained by projecting a sphere region on a plane, accor…
A Survey on QoE-oriented Wireless Resources Scheduling
Ivo Sousa, Maria Paula Queluz, António Rodrigues
Future wireless systems are expected to provide a wide range of services to more and more users. Advanced scheduling strategies thus arise not only to perform efficient radio resou…
