Abstract
An adaptive filter for computation of the Gabor transformation of images is presented. The filter design is based on the LMS algorithm for complex signals. A significant simplification of the filter structure and the use of FFT algorithms lead to a very fast and efficient computation of the coefficients when compared with known algorithms. Further, computer simulations indicate that sufficient precision and a fast convergence of the coefficients can be obtained
