Video Semantic Indexing and Summarization System with Never-ending Learning
- Constructed a well-defined event library, which has over 700 events explored from Wikihow website. Implemented an event query matching and online event training system. Given a queried event, the system will execute a robust similarity matching by ConceptNet and WordNet, then come up with several top ranked events with probability scores. For the no perfect match event query, the system will execute online event video crawling, feature extraction, event modeling and classifier training. Then the event library will be updated with the new event and its classifier.
- Proposed a video summarization algorithm that can generate semantic sequential summarization for each video stream based on existing large-scale event and concept classifiers.

Network Analysis of Live Mouse Brain Neuron Activities
- Given videos of mouse brain captured when they were watching different images, implemented position alignment for each neuron on consecutive video frames and compensated the background luminance; extended Hough transform to detect neurons and to capture active neurons based on SVM classifier.
- Proposed a Cross-Correlation algorithm to construct undirected network topology of mouse brain neuron and captured causality between neurons to conduct directed network via K2 algorithm for Casual Bayesian Network analysis.
- Clustered neurons based on functional segregation via an entropy-based algorithm and implemented 3D visualization of mouse brain neuron network based on the depth and brightness data from video.
