Abstract: With the wide application of biometrics systems and person analysis systems, it is becoming more and more important to ensure their trustworthiness. Untrustable biometrics systems can cause serious ethics and security problems, some of which are newly emerging and quickly gaining tremendous attentions. To name a few, facial recognition and analysis methods may be subject to bias and uncertainty, biometrics systems can be failed under adversarial attacks, imagery of people can maliciously tamper,  and recently  Deepfakes pose a  serious problem against media trustworthiness. In this tutorial, we give a selected coverage on these issues,  featuring detailed introduction on the causes,  treatments,  and prospects of these problems.  We believe that this tutorial is of interest to a  substantial part of the  IJCB  2020  audience.

Prerequisites: The tutorial requires basic knowledge in graduate-level pattern recognition and computer vision. Specifically, the audience should know basic concepts in facial analysis, deep learning, and optimization. We think almost all participants of IJCB have the prerequisite knowledge.

Abstract:

Face is a rich source of signal, conveying various individual information such as identity, age, and expression. In the last few years, with the fast development of deep learning, face recognition has been substantially advanced both in the academia and industry. Evidences are not only the very high scores on large-scale benchmarks but also the extensive real-world applications, e.g., access control and mobile unlock. Meanwhile, recent studies have dedicated to more tasks, including face anti-spoofing, fairness in face analysis, remote physiological signal sensing from face, facial expression classification, and 3D face modeling. They have shown much potential and received persistently increasing attention within the community. This forum focuses on face analysis, covering the topics beyond identification, with six lectures from basic knowledge to latest progress. It will be a high-level seminar to the participants.

Abstract:
Human-centric visual understanding is one of the fundamental problems of computer vision and multimedia under-standing. With the development of deep learning and multi-modalities analysis techniques, researchers have strived to push the limits of human-centric visual understanding in a wide variety of applications, such as intelligent surveil-lance and smart retailing.  This tutorial will present recent advances under the umbrella of human-centric visual understanding, which range from the fundamental problems of person re-identification and gait recognition.  In this tutorial, we will discuss the key problems, common formulations, existing methodologies, real industrial applications, and future directions in the five topics.  Our tutorial views not only come from the research filed, but also combine the real-world requirements and experiences in the industrial community. Therefore, this tutorial will inspire the audiences  from  the  research  and  industrial  community,  and facilitate research in computer vision for human behavior analysis  and  human-centric  analysis  modeling.   We have finished a related tutorial about Human-centric visual understanding in ACM Multimedia Asia 2019. We believe that our tutorial can be of interest to a substantial part of the IJCB 2021 audience.

Prerequisites: The tutorial requires basic knowledge in graduate-level pattern recognition and computer vision.  Specifically, the audience should know some knowledge about image processing, deep learning, GAN. Besides, they  should  know how  to  evaluate  the  performance  of  re-id  and  gait  recognition.

Tutorials session topics:

Person re-identification and gait recognition facilitates various applications that require painful and boring video watching, including searching a suspect person from a city surveillance system, a lost child in a shopping mall from camera videos. Their efficiency and effectiveness accelerate the process of video analysis.  Although existing technologies  have  made  significant  advances  in  standard  datasets, they  are  still  far  from  meeting  the  requirement  of  practical applications.  In this tutorial, we will respectively intro-duce the existing challenges and fundamental technologies in re-ID and gait recognition, and then discuss them from the perspective of data-driven and model-driven methods.

The content of the tutorial is as follows:

•  We will first point out a few unsolved but interesting problems in re-ID. Then, we will give an overview of alternative strategies where datasets undergo various changes, either automatically or manually.  For example, editing synthetic data allows us to augment existing databases; composing a validation/test set makes it possible to evaluate model performance when no test labels are given. We will conclude the tutorial with viable future directions in the re-ID field.

•  We will conclude the existing challenging problems, such as occlusion, a person in similar clothes, model generalization, etc. in re-ID. We will review the recently published massive re-ID methods for addressing these challenges.

•  We will introduce some applications in practical. And then we will introduce some unsupervised methods or self-supervised methods for re-id. •  We will introduce the history, related challenges, advanced methods and some applications of gait recognition
