  9. Video Mining • Boundaries between shots • Movement between frames • ANSES: http://mmir.doc.ic.ac.uk/demos/anses.html

  10. Facial Recognition • Based upon features in face • Convert face to a feature vector • Less invasive than other biometric techniques • http://www.face-rec.org • http://computer.howstuffworks.com/facial-recognition.htm • SIMS: http://www.casinoincidentreporting.com/Products.aspx

  11. Microarray Data Analysis • Each probe location associated with gene • Measure the amount of mRNA • Color indicates degree of gene expression • Compare different samples (normal/disease) • Track same sample over time • Questions • Which genes are related to this disease? • Which genes behave in a similar manner? • What is the function of a gene? • Clustering • Hierarchical • K-means
