Given a finite set of points in three dimensional Euclidean space R3, the subset that forms its surface could bedifferent when observed in different levels of details. In thispaper, we introduce a notion called a-surface. We presentan algorithm that extracts the a-surface from a finite set ofpoints in R3. We apply the algorithm to extracting the a-surfaces of proteins and discover patterns from these surface structures, using the pattern discovery algorithm wedeveloped earlier. We then use these patterns to classify theproteins. Experimental results show the good performanceof the proposed approach.
