In this paper we deal with two important and open problems, the chromaticity detection, i.e. apparent position variation of stellar images with their spectral distribution, and the astronomical aberration detection, using neural networks to analyze and process astronomical images. These tasks can be accomplished thanks to the capability of neural networks to solve a nonlinear approximation problem, i.e. to construct an hypersurface that approximates a given set of scattered data couples. Aberration detection is performed together with the sensitivity matrix analysis that is of particular importance because it allows to investigate the neural network answer to noisy versions of the moments which constitute the actual inputs, of giving useful indications on the robustness of the method. Images are encoded associating each of them with conveniently chosen moments.

Receptor-Based Cellular Neural Network Models

In this lecture, a receptor-based Cellular Neural Network model is considered. Dynamics and stability of such model are studied by applying describing function technique. Comparison of the obtained results with the classical ones is made as well.
