Host: He Xuming
Abstract:
In this talk, I will introduce our recent works that cover open-world visual categorization, reconstruction, and generation. Firstly, I will discuss our recent study on open-world learning, including generalized category discovery and open-vocabulary action recognition on images and videos, respectively, leveraging foundation models. Next, I will present our recent work on generalizable visual SLAM, focusing on the development of a feed-forward SLAM system that eliminates the need for per-scene optimization. We propose an image-based depth fusion framework to achieve this goal. Finally, I will discuss our recent work on 3D human modeling, encompassing both reconstruction and generation perspectives.
