Abstract
A new interpretation of 3 x 3 compass feature masks such as roof edge and F rei-Chen line masks is presented in the one-dimensional (1-D) frequency dom ain, making use of the circularity of the weight matrix. A reduced vector r epresentation is also introduced in consideration of the periodicity inhere nt in the weight vector. (C) 1999 Elsevier Science B.V. All rights reserved .
