Abstract
In this paper, a Cellular Neural Network (CNN) has been applied to a magnet ic regional/residual anomaly separation problem. CNN is an analog parallel computing paradigm defined in space and characterized by the locality of co nnections between processing neurons. The behavior of the CNN is defined by the template matrices A, B and the template vector L We have optimized wei ght coefficients of these templates using Recurrent Perceptron Learning Alg orithm. (RPLA). The advantages of CNN as a real-time stochastic method are that it introduces little distortion to the shape of the original image and that it is not effected significantly by factors such as the overlap of po wer spectra of residual fields. The proposed method is tested using synthet ic examples and the average depth of the buried objects has been estimated by power spectrum analysis. Next the CNN approach is applied to magnetic da ta over the Golatan chromite mine in Elazig which lies East of Turkey. This area is among the largest and richest chromite masses of the world. We com pared the performance of CNN to classical derivative approaches.
