Video mining

Video Mining

  • Boundaries between shots

  • Movement between frames

  • ANSES:

Facial recognition

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:

Microarray data analysis

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
