Deep Domain Adaptation and Fusion for Person Recognition in the Wild

Nuvoola Inc.是一家加拿大公司，提供基于人工智能的云管理服务和解决方案。该公司寻求开发一种软件，用于追踪出现在现实世界视频监控环境中的个人的位置。特别是，Nuvoola寻求开发准确的人员重新识别（Re-ID）系统，允许识别同一个人随着时间的推移出现，并跨越多个分布式摄像头。Re-ID是一个具有挑战性的问题，因为捕获条件的变化，例如，相机的视点，姿势，照明，比例，运动模糊，背景，遮挡。最先进的Re-ID系统采用深度连体网络进行匹配，然而这些深度模型需要对大量不同数量的标记数据进行监督训练，以达到高水平的准确性和鲁棒性。然而，对于现实世界的应用程序，如果在开发和操作环境的捕获条件之间存在相当大的差异，Re-ID的准确性可能会下降。该项目的第一个目标是通过学习领域不变表示来研究和开发适合于现实应用中深度暹罗网络的精确领域适应（DA）的深度学习架构。文献中的一些技术与本项目相关，但在现实世界的Re-ID视频中提供有限的通用性和改进，其中域转移是重要的。第二个目标是研究和开发专门的信息融合深度学习模型，特别是在多模态、时空和基于上下文的融合方面。该项目涉及ETS和Nuvoola Inc.的跨学科团队，将加强思想和资源的交流，并建立长期的合作联系。该项目将专注于从大型且大部分未标记的数据集设计用于视觉识别应用的深度学习模型，并将重点放在最先进的研究上。这项研究项目的重要发现将在高水平的科学期刊和会议上传播，并在Nuvoola视频分析应用程序中加以利用。它还允许培训高素质的人员，以面对战略利益领域当前和未来的挑战。

Nuvoola Inc. is a Canadian company that provides cloud managed services and solutions based on artificial intelligence. It seeks to develop software for tracking the location of individuals appearing in real-world video surveillance environments. In particular, Nuvoola seeks to develop accurate person re-identification (Re-ID) systems that allow recognizing a same person of interest appearing over time, and across multiple distributed cameras. Re-ID is a challenging problem because of variations in capture conditions, e.g., cameras viewpoint, pose, illumination, scale, motion blur, background, occlusion. State-of-the-art systems for Re-ID employ deep Siamese networks for matching, yet these deep models require supervised training on a large and diverse amount of labeled data to achieve a high level of accuracy and robustness. For real-world applications, however, Re-ID accuracy can decline if there is a considerable divergence between the capture conditions of development and operational environments. The first objective of this project is to investigate and develop deep learning architectures that are suitable for accurate domain adaptation (DA) of deep Siamese networks in real-world applications by learning domain-invariant representations. Some techniques in literature are relevant for this project but provide limited versatility and improvements on real-world Re-ID videos, where domain shifts are significant. The second objective is to investigate and develop specialized deep learning models for information fusion, and in particular on multi-modal, spatiotemporal, and context-based fusion. This project involves a cross-disciplinary team from ETS and Nuvoola Inc., and will allow to intensify the exchange of ideas and resources, and establish long-term collaborative links. Focusing on the design of deep learning models for visual recognition applications from large and mostly unlabeled datasets, this project will focus on state-of-the-art research. Significant findings of this research project will be disseminated in high caliber scientific journals and conferences and exploited in Nuvoola video analytics applications. It also allows training of highly qualified personnel to face current and future challenges in areas of strategic interest.
