Merging Image Features by Self-organizing Maps in Content-based Image Retrieval

By Christian Breiteneder, Dieter Merkl, and Horst Eidenberger


This paper shows how merging by linear combination of weighted distance values can be performed. A weighting algorithm is presented for the automatic computation of suitable weights for image features. These features are arranged in query models. The algorithm bases on a self organizing map which describes the "natural" clusters within an image database. We showed that using the contribution of a feature to the cluster structure as weight improves the ordering of query results. The implementation uses IBM QBIC system as kernel and runs under LINUX.
