Work Objectives:
Work Objectives: Visual communications have a fundamental role in Human societies. In the digital era, this has led to the explosion of image and video-based applications and services, notably following the democratization of image and video acquisition, storage and streaming. The recent advances in visual data acquisition and consumption have led to the emergence of the so-called plenoptic visual models, where Point Clouds (PCs) are playing an increasingly important role. PCs are a 3D visual model where the visual scene is represented through a set of points and associated attributes, notably color. To offer realistic and immersive experiences, PCs need to have millions, or even billions, of points, thus asking for efficient coding solutions
Recent years have seen a growing wave of data driven algorithms, such as deep neural networks, which have taken a lead role in many research and development areas, especially in multimedia. This interest is driven by several factors, notably advances in processing power, availability of large data sets, and algorithmic advances. Deep learning (DL)-based solutions are the state-of-the-art for multiple computer vision tasks, both high-level tasks and lower-level tasks. These advances have led to the exploitation of DL-based tools in the image coding domain, reaching competitive performance in a short time. This has been recognized by JPEG (Joint Picture Experts Group) which has just launched the JPEG AI project with the scope of creating a learning-based image coding standard.
The scope of this work is the design, development, implementation and assessment of a DL-based static PC compressed representation targeting both decoding and enhancement consumptions. The DL-based solutions should simultaneously accommodate efficient fidelity-to-original PC coding, with compression efficiency improvements over available solutions, and effective enhanced-from-original PC processing using the same compressed domain stream.
Applicable legislation:
A fellowship will be celebrated according to the regulations defined by FCT, “Regulation of Instituto de Telecomunicações’ fellowships” and “Estatuto do Bolseiro de Investigação”, according to Law no. 123/2019, dated August 28 (Status of Scientific Research Fellow), in its actual redaction, and also by Fundação para Ciência e Tecnologia, I.P.
