Multi-view Face Representation
Date and time:
Room:
Presenters: Zhengming Ding, Handong Zhao, and Yun Fu
Tutorial Description:
Multi-view face data are extensively accessible nowadays, since various types of features, view-points and different sensors tend to facilitate better face data representation. For example, multiple features attempt to uncover various knowledge within each view to alleviate the final tasks, since each view would preserve shared and its own specific information. Recently there are a bunch of approaches proposed to deal with the multi-view face data. Our tutorial will cover most multi-view face representation approaches, centered around three major face applications, i.e., multi-view face clustering, multi-view face verification and multi-view face identification. The discussed algorithms will include matrix factorization, low-rank modeling, multi-view subspace learning, transfer learning, and deep learning.

Remote Physiological Measurement from Images and Videos
Date and time:
Room:
Presenters: Daniel McDuff
Tutorial Description:
In recent years, there have been significant advances in remote imaging methods for capturing physiological signals. Many of these approaches involve analysis of the human face and utilize computer vision to recover very subtle changes caused by human physiology. The resulting signals are clinically important as vital signs and are also influenced by autonomic nervous system activity. There are numerous healthcare and affective computing applications of remote physiological sensing. The first part of this tutorial will cover the fundamentals of remote imaging photoplethysmography. Following this there will be a deeper dive into state-of-the-art techniques for motion and dynamic illumination tolerance. The impact of frame rate, image resolution and video compression on blood volume pulse signal-to-noise ratio and physiological parameters accuracy will be characterized and discussed. Advancements in multispectral and hyper-spectral imaging will also be presented, highlighting how hardware as well as software can be adapted to improve physiological measurement. Finally, examples of visualization techniques and applications will be presented.

From Deep Unsupervised to Supervised Models for Face Analysis
Date and time:
Room:
Presenters: Richa Singh and Mayank Vatsa
Tutorial Description:
Representation learning approaches have become an integral component of designing any pattern analysis system including face recognition. While learning from data is not new, advances in computing hardware and availability of very large training data has instigated widespread attention towards deep learning approaches. Currently, newer deep learning models/architectures and their applications are proposed almost every day. Face recognition literature has also seen a ubiquitous acceptability and results on benchmark databases show that deep learning algorithms have achieved accuracies, which were once considered arduous. The literature on deep learning for face analysis can be divided into three categories: supervised, unsupervised, and semi-supervised. Approaches focusing on synthesizing input such as super-resolution are typically unsupervised, whereas classification/recognition approaches are either supervised or semi-supervised. The applications of deep learning not only focus on face recognition, they also span in several other areas such as kinship verification and super-resolution to address the challenge of recognizing low resolution face images. This tutorial will focus on unsupervised and supervised deep learning models (e.g. autoencoders, Boltzmann machine) and application of different regularization techniques. We will also discuss the applications of these deep regularized architectures in different applications including (i) Face Verification/Classification, (ii) Kinship Verification, (iii) Face Super-resolution, and (iv) Face Presentation Attack Detection.

Statistical Methods for Affective Computing
Date and time:
Room:
Presenters: Jeffrey M Girard and Jeffrey F Cohn
Tutorial Description:
From the evaluation of algorithms to the comparison of experimental groups and approaches, statistical methods are indispensable tools for scientists and engineers interested in affective computing. This tutorial will provide training and hands-on experience with several statistical methods with high relevance in this area. These methods include (1) indexes of categorical and dimensional agreement for quantifying inter-rater reliability and classification performance in a variety of research designs, (2) effect sizes and confidence intervals for quantifying the magnitude and precision of parameter estimates in the presence of sampling error, and (3) general linear modeling for quantifying the strength of the relationship between variables of interest. Attendees will learn the statistical basis of these methods, the assumptions that are required for their use, and standard practices for their implementation, interpretation, and reporting. Syntax, functions, and examples will be provided in both R and MATLAB; attendees are encouraged to bring a laptop with one of these software packages installed.
