ICIG 2021 Symposium：Recent Advances and Future Challenges in Re-Identification
Object re-identification is an important task for multimedia, computer vision machine learning. Great advances have been achieved in extensive areas with the deep learning technique. More and more emerging technologies were proposed both in academic and industrial domain to effectively process various challenges. This symposium will invite four speakers from academic research to industrial application to discuss some novel ideals in re-identification and their applications.

General Instance Re-identification: From Research to Applications
Abstract: The general instance re-identification (re-ID), whose primary tasks are finding a specific person/vehicle/object of interest with the multimedia sensing data, has tremendous potential applications. However, the instance re-ID still faces the challenges of the guarantee of computing timeliness, the complex and instantly changed physical environments, the correlation discovery of massive multiple-modality data, and information security and privacy protection. To solve the challenges, we present a progressive search paradigm, which contains three important search strategies: 1) coarse-to-fine search in feature space; 2) near-to-distant search in spatial-temporal space; and 3) low-to-high permission search in the security space. The strategies all utilize simple features and computation to instantly reduce the search space, in which a complex matching process can be efficiently exploited to find the matched objects finely. Finally, we present our real-world produces implemented in the multimedia sensing network, which demonstrates the proposed progressive search paradigm can significantly improve the general instance re-ID speed and accuracy.

Deep Metric Learning: From Person Re-identification to General Object-of-Interest
Abstract: Person re-identification shares a common keynote, i.e., deep metric learning, with many other computer vision tasks including face recognition and fine-grained image retrieval. Moreover, some recent works on semantic segmentation, video object segmentation and even the unsupervised pre-training also witness the benefit of deep metric learning viewpoint. In this talk, we are to extend the scope from the pedestrian in person re-identification to general object-of-interest, as well as to uncover some novel characteristics of deep metric learning.

Thoughts about unsupervised representation learning for person re-identification
Abstract: Recently, researchers demonstrated that unsupervised learning with large-scale unlabeled training data has the ability to outperform supervised learning on various tasks. With the success of deep learning, self-supervised learning and contrastive learning, unsupervised person re-identification (Re-ID) has achieved increasing attention and made promising achievements in recent years. However, there is still a large gap between the unsupervised and supervised Re-ID especially on challenging dataset. In this talk, I will introduce our recent efforts towards this goal and show the recent developments and challenges in unsupervised person re-identification.

Weakly Supervised Person Re-identification
Abstract: There has been impressive progress in person re-identification (Re-ID) in recent years. However, a large amount of annotations or closed-world data collection scenarios are required for most existing approaches. When extending to large-scale surveillance systems, limited annotation costs and open-world data collection scenario bring new challenges for existing Re-ID methods. Weakly supervised person re-identification has been studied for three types of weak supervisions: incomplete supervision (few labeled samples), inexact supervision (set-level and intra-camera annotations) and inaccurate supervision (noisy label). This talk will briefly introduce the developments and possible future directions of weakly supervised person re-identification.
