Research Summary

My recent research interest is centered around two topics: 1) data-driven shape processing and modeling and, 2) 3D geoemtry-based perception for robot applications. These directions are inspired by the recent fast development of 3D sensing techniques and the proliferation of 3D geometric shape datasets.

Data-Driven Shape Processing and Modeling

Benefiting from the fast development of 3D shape repositories and machine learning techniques, data-driven approach has been widely utilized in shape processing and modeling. The knowledge / patterns about structures and semantics are learned to reason about shape structures for high-level processing, and transferred to the newly generated data. In recent, we are espeically interested in deep generative models of shape structures.

3D Geometry-Based Visual Perception

The recent availability of commodity 2.5D depth sensors has led to a renewed interest in 2.5D object recognition based on depth maps. 3D shapes are playing a more important role in a vision pipeline. 3D geometry not only enhances vision-based recognition but also facilitates 3D spatial interaction for robot navigation and manipulation.
