Work Experience

Internship
  • 2015 Summer. Research Intern. Intel Labs, CA, USA. Systems and Software Research Lab.
  • Stereo-constraining multi-view video stabilization: an algorithm that consistently stabilizes multiple video streams, extensive programming in C++, Matlab, OpenCV and OpenGL
    Patent filed: Multi-view Video Stabilization

Research Projects

  1. Stereoscopic panorama stitching (C++, Matlab, OpenCV and OpenGL; in CVPR2015)
    - Designed and implemented a stereoscopic stitching technique to help amateur users create high-quality stereoscopic panoramas for 3D and virtual reality head-mounted devices
  2. Parallax-tolerant image stitching (C++, Matlab, OpenCV and OpenGL; in CVPR2014)
    - Designed and implemented an image stitching algorithm to create high-quality panoramas from casually taken images, outperforming existing state-of-the-art algorithms including the commercial version of Photoshop;
    - With significant industry interests from Adobe, IBM, Google, Apple, Intel and Flickr
  3. Multi-lens video compression (C++ and JMVC)
    - Developed a multi-lens video compression method which takes advantage of inter-lens correlation to make video compression efficient; explored compression trade-offs; designed for VR real-time content transmission
  4. Multi-lens stereoscopic video benchmark (Matlab and Maya; in MMSys 2015)
    - Created the first benchmark for multi-view image and video research
  5. Video stitching (C++, Matlab, OpenCV and OpenGL)
    - Developed an algorithm for consistently stitching multiple casually taken videos together to create high-quality video panoramas; programmed in C++, Matlab, OpenCV and OpenGL
  6. Smart stereoscopic 3D photo editing system (C++, Matlab, OpenCV, OpenGL, FLTK and Weka; in ICME2013)
    - Designed and implemented a smart photo editing system, powered by a well-trained logistic regression model;
    - Experimented with multiple machine learning models including Decision Trees, SVM and Neural Network with Weka and LibSVM; data-mining with a large dataset of 3780 stereoscopic 3D images
  7. Hand-written digit recognition (Matlab and Weka)
    - Experimented with hand-written digit recognition using different classifiers including Decision Tree, Neural Network, SVM, SVM ensembles, Naïve Bayes and K-means clustering; compared and analyzed performances
