Robust Face Recognition for Data Mining

While the technology for mining text documents in large databases could be said to be relatively mature, the same cannot be said for mining other important data types such as speech, music, images and video. Multimedia data mining attracts considerable attention from researchers, but multimedia data mining is still at the experimental stage (Hsu, Lee & Zhang, 2002). Nowadays, the most effective way to search multimedia archives is to search the metadata of the archive, which are normally labeled manually by humans. This is already uneconomic or, in an increasing number of application areas, quite impossible because these data are being collected much faster than any group of humans could meaningfully label them — and the pace is accelerating, forming a veritable explosion of non-text data. Some driver applications are emerging from heightened security demands in the 21st century, postproduction of digital interactive television, and the recent deployment of a planetary sensor network overlaid on the internet backbone.
