Coding
  • Homogeneity
  • - continuous and homogenous on appearance
  • - possible to detect outline/shape object
  • Compactness
  • - tend to be connected together
  • - parts usually closed tied together
  • Symmetry
  • - most natural object have a symmetry
  • - detected as a strong feature for indexing

4
Indexing
  • Inversion of terms
  • - selecting keywords and use them as index
  • Multi-attribute
  • - data coded into several categories based on
    bit pattern
  • - signature (index and retrieved used)
  • Clustering
  • - coded by several categories, stored in a
    vector
  • - using similarity matrices

5
Retrieval
  • Query by Contents
  • Iconic Query
  • SQL Query
  • Mixed Query
