  1. In collaboration with: Computer Vision Group Indexing Video Sequences

  2. Low level features in video sequences Goal: Indexing Video repositories based on the low level features. • Color (Red, Green, Yellow, Blue) • Orientation (0 degree, 45 deg, 90 deg, 135 deg) • Intensity (High, Low) • Directional Motion (Left, Right, Up, Down)

  3. How do you index this data? • Using the frame number? • Using the color? • Lots of efficient retrieval issues.
