Abstract

The problems associated with applying the discrete cosine transform (DCT) to the design and implementation of the 1-D isotropic quadratic filter are investigated in this paper. A DCT implementation of the filter is proposed and its computational complexity is analysed. The advantage of the DCT implementation is illustrated by a nonlinear system modelling problem. Results show that the DCT implementation converges faster than the direct implementation
