<title>House extraction with multiresolution analysis and information fusion</title>

Abstract

Houses are key elements both in aerial photographs and maps. The extraction of them has significance not only to military, but also to automatic relative orientation, automatic absolute orientation, feature-based matching, systematic description, automatic data acquisition, structure analysis, image understanding, digital mapping, and construction of urban geographic information system. For this purpose, this paper mainly addresses (1) a brief introduction to the multiresolution analysis of wavelet theory and its difference from Laplacian pyramid, (2) how to generate the multiresolution images and edge features, and (3) how to employ these multiresolution images and edge features to extract the houses from aerial photographs by multiresolution structure and information fusion.© (1994) COPYRIGHT SPIE--The International Society for Optical Engineering.
