Efficient Motion Vector Refinement Architecture for Sub-Pixel Motion Estimation Systems
Tiago M Dias,
Instituto Superior de Engenharia de Lisboa (ISEL) –
In this talk it will be presented a new, scalable and efficient VLSI architecture for real-time sub-pixel motion estimation. The presented structure is optimized for search strategies using small search ranges, such as hierarchical or sub-pel refinement algorithms. Based on this architecture, a highly modular and configurable motion estimation co-processor will be also presented, capable of estimating optimal motion vectors with any given accuracy and using any known interpolation algorithm. The performance of this processing structure has been evaluated by embedding it in a two-level motion estimation system with minimum memory bandwidth requirements, that estimates half-pixel accurate motion vectors using a two-step search procedure. Experimental results for implementations on ASIC and FPGA devices will be presented, showing that by using this new architecture it is possible to estimate motion vectors up to the 4CIF image format with any given sub-pixel accuracy in real-time.

Title: Workshop Metabolism and mathematical models: Two for a tango – 2nd Edition
Dates: October 25-26, 2022
Location: This workshop will be held in a virtual way
The topic of this workshop is metabolism in general, with a special focus, although not exclusive, on parasitology. Besides an exploration of the biological, biochemical and biomedical aspects, the workshop will also aim at presenting some of the mathematical modelling, algorithmic theory and software development that have become crucial to explore such aspects.
This workshop is being organised in the context of two projects, both with the Inria European Team Erable. One of the projects involves a partnership with the University of São Paulo (USP), in São Paulo, Brazil, more specifically the Institute of Mathematics and Statistics (IME) and the Institute of Biomedical Sciences – Inria Associated Team Capoeira – and the other involves the Inesc-ID/IST in Portugal, ETH in Zürich and EMBL in Heidelberg – H2020 Twinning Project Olissipo.
The workshop is open to all members of these two projects but also, importantly, to the community in general.
The program and more details are available here.
