Blog for work on my Masters thesis - a survey of methods for evaluating media understanding, object detection, and pattern matching algorithms. Mostly, it is related to ViPER, the Video Performance Evaluation Resource. If you find a good reference, or would like to comment, e-mail viper at cfar.umd.edu.

Algorithms for approximate string matching

Ukkonen's paper on string matching seems important, but I've been unable to find a copy. I hate when you see a paper referenced in a bunch of papers that are useful, but can't find the source in print.

Brief Introduction to ViPER Metadata

I have been working on ViPER for a while. As I have a fair knowledge of XML and video metadata, I will probably be lending a hand in the Malach project. An interesting component, VideoMiner, is being written here at LAMP, and it should use the same metadata format developed for ViPER.
