Large-scale image classification and video highlight retrieval

April 21, 2014, 3:00 - 4:00, NSH 1507

In the age of big data, it is critical to develop scalable methods to address challenges in the real-world. In the first part of my talk, I will present a novel method to efficiently and robustly classify a large number of object categories. The proposed "find the best path" method achieves a significantly better trade-off between classification accuracy and time-efficiency than other existing methods. The proposed method is beneficial for various applications which require different trade-off between accuracy and efficiency. In the second part of my talk, I will present a fully automatic system to retrieve domain-specific highlights in raw personal videos. Given a domain-specific query such as "surfing", our system mines the Youtube database to analyze how users generate edited surfing videos. Then, the mined information is used to train our domain-specific ranker to retrieve highlights from unseen raw person videos. This work addresses the critical need toward automatic video editing to increase audience retention of personal videos.
