This paper is concerned with the implementation of oriented Gaussiantype filters with several possible decomposition schemes, including the steerable approach and the wavelet transform. A novel spatial decomposition scheme is introduced, in which the filters are projected onto a set of Gaussian basis functions which are not dependent on the orientation of the filters. This scheme only costs a few multiply/add operations per pixel per orientation and provides a considerable improvement in efficiency.
