In this paper, multi-level genetic cellular neural networks (ML-GCNN) are applied to the geophysical problem of potential anomaly separation and satisfactory results are obtained, compared to classical deterministic approaches. ML-GCNN is a stochastic image processing technique which is based on template optimisation using neighbourhood relationships of the pixels. The residual anomaly separation used in location decisions is one of the main problems in geophysics. The method proposed here is used in evaluating the Dumluca iron ore region of Turkey.

Within thc programmable opto-electronic analogic computer (POAC) framework B new, feed forward only optical CNN-UM implementation has been introduced. It is grounded on an innovative semi-incoherent optical correlator architecture. Angular coding of the template pixels determines the operation o f this optical CNN implementation, therefore it is rcal time and flexibly programmable. We have demonstrated its feasibility and operation by an experimental setup. Our correlator architecture makes it possible to execute algorithms real time, which cannot be done by any other existing optical conclator so far. Our architechue unifies the advantages of coherent and incoherent optical correlators, provides a more robust frame and avoids their main hindrances. In the POAC framework the resulting conelogram is measured by a programmable adaptive sensor array, a special visual CNN-UM chip. So, local parallel programs fulfill both the necessary pre and post processing with the required adaptive thrcsholdiog. HOWCVCI, because of the limited resolution of available visual CNN chips ( 28x 28), all-optical optical prcandpost-precessing will be used, as well.

Some parallel channels of the mammalian retina are illustrated schematically. The different decomposition possibilities are indicated by the cyan blocks. The different neuron types in the retina are organized into two-dimensional stmta modeled with CNN layers, which are represented by the spheres. A neuron in a given layer effects another neuron in another layer through synapses while the arrows represent the connections. The layers have different time and space constants and the synapses produce non-linear transfer functions.
