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…
Neuromorphic Vision Data Coding: Classifying and Reviewing the Literature
Catarina Brites, João Ascenso
In recent years, visual sensors have been quickly improving towards mimicking the visual information acquisition process of human brain by responding to illumination changes as the…
Low Complexity Learning-based Lossless Event-based Compression
Ahmadreza Sezavar, Catarina Brites, Joao Ascenso
Event cameras are a cutting-edge type of visual sensors that capture data by detecting brightness changes at the pixel level asynchronously. These cameras offer numerous benefits o…
Learning-based Lossless Event Data Compression
Ahmadreza Sezavar, Catarina Brites, Joao Ascenso
Emerging event cameras acquire visual information by detecting time domain brightness changes asynchronously at the pixel level and, unlike conventional cameras, are able to provid…
