Overview

Computer Vision strives to develop algorithms for understanding, interpreting and reconstructing information about real-world scenes from image and video data.

Computer Graphics focuses on image synthesis: algorithms to build and edit static and dynamic virtual worlds and to display them in photorealistic or stylized ways.

Both fields have witnessed the transformative effects of deep learning and neural networks, thus ushering the so-called Neural Age.

In this seminar, we will explore how the classical concepts in Computer Vision and Computer Graphics have manifested in the Neural Age. We will seek to understand if and how the new neural methods have changed the way we think about these problems, and how they have improved the state-of-the-art. For each topic that we cover, we will discuss a seminal paper that has shaped the field and also discuss a recent paper that has further developed that idea in a modern context. This seminar will cover research papers from the following topics:

image and video generation, manipulation, and analysis,
multi-view geometry and reconstruction,
computational photography and videography,
shape matching,
pose estimation, tracking, and character animation,
deep learning for computer vision and computer graphics.

Topics

The following table lists more topics than available weeks – this is to allow some flexibility for the interests of the group to change the course structure. Once every participant has submitted their choice of topics, this list will be updated to show the presenter of each topic. Send us an email if you cannot access a paper for some reason.
