Fish4Knowledge: Collecting and Analyzing Massive Coral Reef Fish Video Data
This book gives a start-to-finish overview of the whole Fish4Knowledge project, in 18 short chapters, each describing one aspect of the project. The Fish4Knowledge project explored the possibilities of big video data, in this case from undersea video. Recording and analyzing 90 thousand hours of video from ten camera locations, the project gives a 3 year view of fish abundance in several tropical coral reefs off the coast of Taiwan. The research system built a remote recording network, over 100 Tb of storage, supercomputer processing, video target detection and

Interesting faces: A graph-based approach for finding people in news
Cataloged from PDF version of article.In this study, we propose a method for finding people in large news photograph and video collections.
Our method exploits the multi-modal nature of these data sets to recognize people and does not require
any supervisory input. It first uses the name of the person to populate an initial set of candidate faces.
From this set, which is likely to include the faces of other people, it selects the group of most similar
faces corresponding to the queried person in a variety of conditions. Our main contribution is to
transform the problem of recognizing the faces of the queried person in a set of candidate faces to the
problem of finding the highly connected sub-graph (the densest component) in a graph representing
the similarities of faces. We also propose a novel technique for finding the similarities of faces by
matching interest points extracted from the faces. The proposed method further allows the
classification of new faces without needing to re-build the graph. The experiments are performed on
two data sets: thousands of news photographs from Yahoo! news and over 200 news videos from
TRECVid2004. The results show that the proposed method provides significant improvements over textbased
methods.
