Worked under the supervision of Professor Kwang-Ting (Tim) Cheng on computer vision algorithm adaptation to mobile devices, local feature design and its application to mobile augmented reality and image retrieval. Proposed novel techniques for accelerating local feature point detection on mobile devices, designed new binary feature descriptors that are ultra-fast to compute, compact to store and transmit on mobile devices while remaining sufficiently distinctive and robust.
Collaborated with Dr. Qiong Liu and Dr. Chunyuan Liao on scalable image matching techniques and human-computer interaction design for interactive paper system. Designed new matching algorithms for identifying images from million-scale databases with over 99% accuracy and real-time performance. Proposed and developed MixPad, a novel interactive paper system, which allows users to exploit mice and keyboards to digitally manipulate fine-grained document content on paper.

Collaborated with Dr. Qiang Zhu on objectionable image filtering and partial-duplicate image detection. Developed an objectionable image filtering system based on SIFT-feature representation and bag-of-words model. Designed a new local feature descriptor that is faster and much more compact than SIFT while maintaining a similar detection rate and precision. Developed a partial-duplicate image detection system using the new feature representation and locality sensitive hashing.
