The founding and application of pattern database for building recognition

The founding of building pattern database is the key technique of building recognition of high resolution remote sensing imagery. This paper founded a simple pattern database by extracting the characteristics of building in remote sensing imagery and summing up several building patterns. Next, on the basis of patterns from the pattern database, this paper used the wavelet descriptor to describe the characteristics of buildings and utilized its affine invariant to recognize them. Then an image of Peking University was taken as an example to do the experiment. The result proved the method of founding pattern database was feasible.
