About Me

I am a fourth-year Ph.D. student in TUM, under the guidance of PD Dr. Slobodan Ilic and Prof. Nassir Navab. Prior to TUM, I spent six wonderful years at NCKU where I had the chance to work with Jar-Ferr Kevin Yang and completed my BSc in Electrical Engineering and MSc in Computer Engineering. In the past few years, I've also had the pleasure to work with: Dr. Yu-Chiang Frank Wang in team MML, Academia Sinica; Dr. Edmond Boyer in team Morpheo, INRIA; Dr. Federico Tombari in CAMP; MIX team in Microsoft Research Redmond; and Capture and Effects team in Disney Research Zürich.

I'll be available in the job market from Spring 2017. If you have questions or anything to discuss with me, please feel free to drop me an email.

Spatio Temporal Modeling of Dynamic Scenes

Spatio Temporal Modeling of Dynamic Scenes

A great part of Computer Vision research has been dedicated to shape recovery, tracking and detection of 3D objects in images and videos. While excellent results have been achieved in these areas, the majority of the methods still assume static scenes and rigid objects, and rarely explore temporal information. However, the world surrounding us is highly dynamic, and in many situations objects deform over time. This temporal information provides a richer and denser source of information and have not yet been extensively exploited. Our objective within this project is to explore spatio-temporal information in order to recover 3D shapes and the motion of the deformable objects. Therefore, we refer to this area as spatio-temporal or four dimensional modeling (4D modeling). With the increased popularity of 3D content in film industry, TV, Internet and games, tools and methods that exploit spatio-temporal information and allow fast and automated 3D content production are going to be indispensable.

Inferring correspondences via regression forest

User-specific Human Shape Detection in Full 3D data (surface-based)

Inspired by the recent work that applies random forests to estimate human poses with depth data (either via body part classification or dense correspondences), in this project we investigate the possibility to infer the dense correspondences between a surface model and a complete 3D visual hull obtained in multiple camera environments. With frame-wise data-model associations, our method is able to detect human shapes in a clutter scene, which we term tracking-by-detection of 3D human shapes.
CRF

Markov Random Field for Regularizing Matches between Meshes

The inferred data-model associations from the forests often look noisy because it does not respect the intrinsic structure, i.e. triangles/edge connectivity. In this project, we mitigate this by proposing a new way to aggregate leaf-node predictions from forests. As the correspondences are highly interdependent among the local neighborhood, we apply random fields (MRF/CRF) to regularize them, yield the optimal configuration w.r.t. the whole shape. The aggregation is therefore mesh-based rather than vertex-based.
volumtriccorrespondences via regression forest

Volumetric Tracking by Detection

Following the above tracking-by-detection concept, in this project we investigate different parameterizations of 3D shapes. We choose centroidal Voronoi tessellation (CVT) as the shape representation and realize discriminative correspondences in a volumetric manner. We further propose a unified volumetric tracking-by-detection pipeline, where the shape representation, deformation model, feature description, and primitive association are all built on a single consistent representation, CVT.
tracking without BS

Human Shape and Pose Tracking without Background Subtraction

In this project, we investigate the possibility to recover human motions directly with images, without doing background subtraction. The 3D surfaces are expected to be textured, or at least contain per-vertex color information. Thus, the problem amounts to maximizing the similarity between the projected texture of surfaces and the image observations.
