The initial analysis of any large data set can be divided into two phases: (1) the identification of common trends or patterns and (2) the identification of anomalies or outliers that deviate from those trends.

Automated detection of new, interesting, unusual, or anomalous images within large data sets has great value for applications from surveillance (e. g., airport security) to science (observations that don't fit a given theory can lead to new discoveries).
