Abstract
We present a framework for content based retrieval (CBR)
of remotely sensed imagery. The main focus of our
research is the segmentation step in CBR. A bank of gabor
filters is used to extract regions of homogeneous texture.
These filter responses are utilized in a multiscale
clustering technique to yield the final segmentation. Novel
area morphological filters are utilized for the purpose of
scaling. The resultant segmentation yields regions that are
homogeneous in terms of texture and are significant in
terms of scale. These regions are used for the purpose of
extracting shape and textural features (on a global and
