[edit] Symbolic Images
Natural Images cannot be stored in database systems as it is for retrieval. Querying the image on the basis of topology and physical features is very difficult.
Hence the natural image is converted into symbolic image. This conversion includes the conversion of many objects consisted in the image to iconic labels, with the centroid of the object being the reference position.
Thereby the image is now reduced to a 2-dimensional cartesian graph.
