Point Cloud Geometry Scalable Coding Using a Resolution and Quality-Conditioned...

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 encode multiple independent streams, each covering a different possible requirement for the clients, with an obvious negative impact in both storage and computational requirements. These drawbacks can be avoided by using codecs that ...

A Double Deep Learning-Based Solution for Efficient Event Data Coding and Class...

Event cameras have the ability to capture asynchronous per-pixel brightness changes, usually called "events", offering advantages over traditional frame-based cameras for computer vision tasks. Efficiently coding event data is critical for practical transmission and storage, given the very significant number of events captured. This paper proposes a novel double deep learning-based solution for efficient event ...

The JPEG Pleno Learning-Based Point Cloud Coding Standard: Serving Man and Machine

Efficient point cloud coding has become increasingly critical for multiple applications such as virtual reality, autonomous driving, and digital twin systems, where rich and interactive 3D data representations may functionally make the difference. Deep learning has emerged as a powerful tool in this domain, offering advanced techniques for compressing point clouds more efficiently than conventional coding metho...

Scalable Graph-Guided Transformer for Point Cloud Geometry Coding

Attention models, particularly Transformers, have significantly advanced deep learning in fields like natural language processing and computer vision by capturing contextual relationships in both sequential and spatial data. This ability is valuable for Point Clouds (PC), which are unstructured sets of points in 3D space. Transformers can effectively identify correlations between distant points, allowing them t...

Petrel extinction in Macaronesia (North-East Atlantic Ocean): the case of the g...

The Late Quaternary fossil record indicates that formerly in the North Atlantic volcanic Macaronesian archipelagos (Azores, Madeira, Selvagens, Canary Islands, and Cape Verde) there was a higher avian diversity, including numerous now extinct species. Currently, only three gadfly petrels (genus Pterodroma) remain in two archipelagos: the Fea’s petrel, Pt. feae, in Cape Verde (islands of Santiago, Fogo, Santo An...

EU needs groundwater ecosystems guidelines

Negotiations are underway on the new European Union (EU) Water Directive (1), which will regulate the protection and sustainable use of Europe’s water resources. However, the proposal foregoes environmental quality standards specifically tailored to sensitive groundwater species and fails to require biomonitoring for groundwater ecosystems. Despite repeated calls for consideration (2, 3) since the first Water F...

Practical wisdom in social work: ethnographic study of professional daily life

In this article, we investigate the challenges faced by social service professionals in a changing society, increasingly complex and uncertain. Analyzing specific situations from a short-term ethnographic study, we aim to describe and interpret the various forms of knowledge expressed by professionals in their daily social interactions with their counterparts. We emphasize the growing relevance of practical wis...

Pseudo-escorpião-cavernícola, Pseudoblothrus oromii Mahnert, 1990

ATUALMENTE são conhecidas cerca de 340 cavidades vulcânicas nos Açores, as quais representam um património natural único, quer pela sua riqueza geológica, quer pela grande diversidade de seres vivos que albergam. Com o intuito de dar a conhecer um pouco melhor os organismos dos habitats subterrâneos dos Açores, iniciou-se na edição de 2018 do Pingo de Lava uma coleção de fichas com informação sucinta sobre taxo...
