Compression of Images from Emergent Modalities

on 07-07-2020

... This is a IT internal project, developed in collaboration with BioImaging Austria and i3S – Instituto de Inovação e Investigção em Saúde, University of Porto. (see more)

The advances in the field of medical imaging have pushed the research institutes and medical facilities storage capabilities to the limit, with huge amounts of data being generated everyday. To cope with this issue, novel methods to compress the generated data must be developed. Such methods shall be among three categories: (i) lossless methods (whose output can be perfectly reversed in the original data); (ii) near-lossless methods (whose degradation in the resulting data cannot be perceived either by the human eye or does not impact the results of the automatic processing systems), (iii) lossy methods (in particular cases only a small segment of the data presents important data, so some distortion is acceptable in the remainder).

In line with these technological developments and requirements, the main goal of this project is the development of coding approaches specifically designed to alleviate data storage and transmission bottlenecks, which are emerging from the use of optical imaging modalities such as Light-Sheet Fluorescence Microscopy (LSFM), High-Resolution Episcopic Microscopy (HREM), and histological Whole-Slide Images (WSI), due to their data volumes, which individually may easily exceed few Terabytes of data.

Illustration: Data compression is the process of reducing overall size of the data so that it can be easily transmitted and stored

SNOB-5G: Scalable Network Backhauling Solution for 5G

on 29-06-2020

... The project’s kick-off meeting took place on February 2nd, hosted by Ubiwhere (Project’s Coordinator) at the company’s headquarters in Aveiro, Portugal. (see more)

SNOB-5G is a recent PT2020 project, that will be carried out over the next three years, where the main objective is to boost the expansion of 5G by fostering a cost-effective, sustainable and reliable system to deploy a secure and high-quality 5G network service. A team composed of researchers from IT, Ubiwhere, the Centre of Informatics and Systems of the University of Coimbra and MIT (Cambridge, USA) will focus on the research and development of self-optimized, inteligent and fault-tolerant backhaull solutions for 5G networks that will empower cities as neutral hosts (a shared network solution provided on an open access basis to all Mobile Network Operators), capable of accommodating new and innovative urban services (such as intelligent transportation systems).

By setting an intelligent solution that leverages existing urban furniture SNOB-5G will overcome the challenges of 5G distribution, even in areas with a high density of devices, sensors and services, fostering a highly resiliente network with no point of failure. In the end, the proposed solution will be validated in two municipalities, under distinct city-wide use cases with specific and challenging requirements.
