André F. R. Guarda, Nuno M. M. Rodrigues, Fernando Pereira
While point cloud-based applications are gaining traction due to their ability to provide rich and immersive experiences, they critically need efficient coding solutions due to the…
Point Cloud Geometry Scalable Coding Using a Resolution and Quality-conditioned Latents Probability Estimator
Daniele Mari, André F. R. Guarda, Nuno M. M. Rodrigues +2
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…
Deep Learning-based Event Data Coding: A Joint Spatiotemporal and Polarity Solution
Abdelrahman Seleem, André F. R. Guarda, Nuno M. M. Rodrigues +1
Neuromorphic vision sensors, commonly referred to as event cameras, generate a massive number of pixel-level events, composed by spatiotemporal and polarity information, thus deman…
