This project is about making 3D Avatars move automatically. The topics that I have been looking into are complex human motion synthesis and motion planning using deep learning and the continuity problem in the motion representations in deep neural networks.

The project is about finding the deep representation for 3D hair geometries and automatically tracking and reconstructing human hairs from single or multi-view cameras. We designed the first deep neural neural network that can fastly infer high-resolution 3D hairs. We also provide an open-source [dataset] that contains 40 thousand synthetic hair models.
The project is about Track the expressions and textures of the face from videos, then synthesize new facial images and video with given expressions, e.g. swap the face between two videos.

Inspired by the hologram system in manga "Psycho Pass" I design the Pmomo (projection mapping on movable object) system to create the phantasm of real-world objects being covered with virtual exteriors. As supporting 6-DOF object motion, the system can keep tracking the object and projecting 3D texture on its surface in real-time. Meanwhile, occlusions are culled from projection as to improve the sense of realism. In the picture left, the models held in the user' hands were originally white but now rendered with vivid textures by projection.

It is a cloud powered magic that enable users to grab pictures and music directly from the screen, carrying around the data and put them 'into' other smart devices. Through hand commands, the files are transferred from device-to-device without any extra equipment. For watching the videos: [fun] [child] [demo]

Clio is an android app that makes painting a new way of communication. It allows users to do synchronous painting and picture transmission on more than three Android devices via Wi-Fi and Bluetooth. To make it more fun, Clio also generates special effects when 'telepathy' happens between the users.

In the field of human motion recognition methods, the objective of this research is to transform motions into images and accurately recognize the motion images, under very small training sets.
I developed this software to create a windows application that can make the avatars follow the facial and body actions of the users in real time. In the left picture, I am controlling 'Sponge Bob' to perform funny actions of nodding and laughing. My method is building several key facial expression models, and morphing them into a new expression according to the facial coefficients tracked by Kinect.
AVAT is a medical application based on Kinect, and it can offer multiple self-catering vision test items, including: visual acuity test, chromatoptometry test and stereopsis vision test. It is very easy and convenient for hospital and home usage. Plus, AVAT can track the vision test results, helping the specialists to assess the change of visual condition, e.g. parents willing to monitor the vision acuity of their children. With the popularization of the AVAT system in medical institutions, schools and communities, it could solve the issue of the overloaded physical examinations in China.

In the summer of 2012, I traveled to Sweden with my university's choir and chanced upon this beautiful lake in our way leaving. When I came back home, I painted the view I saw.

In this work, I restored the details of the ancient painting, and adding my own creativity into the lines.
