Worked at Google Photos on automatic Cienmagraph animation creation from video. Filed one patent through this project. - Video decoding (FFMpeg on Android) and stabilize/crop the hand-holed recoded videos.- Discover the animation parts in video scene using optical magnitude.- Generate smooth loops locally in video animation parts and encode animations into a .gif file.- Submit around 20 change lists into Google code repository. Got familiar with industry software devel- opment pipeline (coding/designing style, creating unit-tests, doing code review).

Work in Qualcomm multi-media research group, built a live speech driven facial animation system.Submitted 2 patents through this project.1. Implement live speech animation system from scratch, in C++ and OpenGL. Use Boost library foraudio/animation synchronization, build the user interface using QT.2. Facial motion data compression using Principal Component Analysis. Motion segments labelingusing K-Mean clustering. Motion data denoise using Low-Pass Filter.3. Off-line speech audio recognition using HTK. Set up the live phoneme recognition using JULIUS

Joined the Huanshi Network Technology, worked on 3D facial construction project.1. Developing video-based human face model 3D reconstruction prototype from scratch in C++.2. Implement RBF algorithm and develop user interface system to let artists generate face database.3. Building 3d model re-construction pipeline using OpenCV, and Morphable Model with face database.4. Find the facial feature points correspondence among video frames using FLANN.5. Use Active Appearance Model to track the facial features in video stream of mobile phone, andsynthesis realistic facial texture using Laplacian Operation and Harmonic Field.
