摘要：A knowledge-based, hierarchical, unsupervised classification scheme forhigh resolution multispectral satellite images is proposed. This scheme,which finds its conceptual bases in the work of Nagao and Matsuyama(1980) for structural analysis of aerial photographs, introduces a newfiltering algorithm which is able to preserve fine linear structures of theimage.The classification products are: 1) a raster image where detectedoutput classes are characterized by some specific information contentand/or by spectral separability (by cluster analysis); 2) property tablesdescribing each elementary region in terms of descriptive and geometricattributes; 3) geometry of output elementary regions converted tovector format.An example of the application of this classification scheme to aLandsat TM multispectral image is presented.Key Words: satellite image classification, knowledge-based classification,image understanding.
