Learning for Multi-View Tracking
In response to the growing trend towards end-to-end learning, we propose a novel framework advancing towards an end-to-end multi-camera multi-object tracking (MC-MOT) solution that addresses challenges like occlusions, viewpoint variations, and illuminatio ...
2023Better Patch Stitching for Parametric Surface Reconstruction
Pascal Fua, Mathieu Salzmann, Zhantao Deng, Jan Bednarík
Recently, parametric mappings have emerged as highly effective surface representations, yielding low reconstruction error. In particular, the latest works represent the target shape as an atlas of multiple mappings, which can closely encode object parts. A ...
IEEE2020The PCL Theorem: Transactions cannot be Parallel, Consistent, and Live
Rachid Guerraoui, Victor Bushkov, Panagiota Fatourou
We establish a theorem called the PCL theorem, which states that it is impossible to design a transactional memory algorithm that ensures (1) parallelism, i.e., transactions do not need to synchronize unless they access the same application objects, (2) ve ...
ASSOC COMPUTING MACHINERY2019Distributed Transactional Systems Cannot Be Fast
Rachid Guerraoui, Willy Zwaenepoel, Diego Didona, Junxiong Wang, Panagiota Fatourou
We prove that no fully transactional system can provide fast read transactions (including read-only ones that are considered the most frequent in practice). Specifically, to achieve fast read transactions, the system has to give up support of transactions ...
2019Fast General Distributed Transactions with Opacity
Aleksandar Dragojevic, Stanko Novakovic, Georgios Chatzopoulos
Transactions can simplify distributed applications by hiding data distribution, concurrency, and failures from the application developer. Ideally the developer would see the abstraction of a single large machine that runs transactions sequentially and neve ...
ASSOC COMPUTING MACHINERY2019The Consensus Number of a Cryptocurrency
Rachid Guerraoui, Dragos-Adrian Seredinschi, Matej Pavlovic, Matteo Monti
Many blockchain-based algorithms, such as Bitcoin, implement a decentralized asset transfer system, often referred to as a cryptocurrency. As stated in the original paper by Nakamoto, at the heart of these systems lies the problem of preventing double-spen ...
ASSOC COMPUTING MACHINERY2019IntegrCiTy - D2.3 Report - Enabling and integrating a common IT structure: Definition of a back-end layer architecture
François Maréchal, Luc Girardin, Jessen Page, Gillian Jean Bernard Basso
The concept of the IntegrCiTy platform is built around the development of a single application as a suite of independent software: project partners will mutualize a certain number of tools that shall be integrated in the IntegrCiTy platform. Therefore, a r ...
IPESE-EPFL2017Boundary-aware Instance Segmentation
We address the problem of instance-level semantic segmentation, which aims at jointly detecting, segmenting and classifying every individual object in an image. In this context, existing methods typically propose candidate objects, usually as bounding boxe ...
