[Seminar] Analysis and Generation of Visual Data using Deep Learning

Monday, January 23, 2023

11:00 am - 12:00 pm


Ioannis Patras, Ph.D.

Professor in Computer Vision and Human Sensing

Director of Graduate Studies (Research)

Queen St. Mary, University of London

PGH 232


Recent years have witnessed an unprecedented interest in the analysis and generation of images and image sequences using Computer Vision methodologies. In this talk we will first show some of our recent works in analysis of images sequences with applications on video retrieval, few shot action recognition and affect recognition. Methodologically, we will present a framework for learning to compare image sequences and how knowledge distillation can be used to achieve different trade-offs between accuracy, speed and storage requirements. In the second part of the talk, we will present our recent work on controllable (facial) image generation that is based on the analysis of the latent space of Generative Adversarial Networks (GANs). We will give a brief introduction to GANs and then present two methods that find non-linear, interpretable directions in the latent space, so that edits along them can control image attributes such as pose, facial expressions and hair colour either in an unsupervised manner, or with guidance from Natural Language sentences.
