In this paper, we describe the architecture and initial implementation of a content-based retrieval mechanism from heterogeneous image archives. In particular, we propose an architecture to produce local representation of the images stored in heterogeneous archives and a progressive framework that reorganizes the images into a hierarchical representation based on a multiresolution decomposition and an abstraction pyramid. Search operations can rely on this representation and be performed in a hierarchical fashion, thus significantly reducing the total amount of data that need to be processed. Dramatic speedup has been achieved for many search operations, such as template matching, texture feature extraction, and histogram extraction.
