  1. Components of the Retrieval System

  2. Color Features

  3. Color Features (cont.)

  4. Color Features (cont.) I or V S (explain more details)

  5. Similarity measurements • Four similarity measurements or distance functions are used. • L1-norm (City-block, Manhattan) • L2-norm (Euclidean) • L∞-norm (Dominance, Chessboard) • Normalized Euclidean Distance

  6. Evaluation • We use Precision concept to evaluate the effectiveness of each feature set and similarity measurement. • Precision =
