Bio-inspired log-polar based color image pattern analysis in multiple frequency channels

The main topic addressed in this thesis is to implement color image pattern recognition based on the lateral inhibition subtraction phenomenon combined with a complex log-polar mapping in multiple spatial frequency channels. It is shown that the individual red, green and blue channels have different recognition performances when put in the context of former work done by Dragan Vidacic. It is observed that the green channel performs better than the other two channels, with the blue channel having the poorest performance. Following the application of a contrast stretching function the object recognition performance is improved in all channels. Multiple spatial frequency filters were designed to simulate the filtering channels that occur in the human visual system. Following these preprocessing steps Dragan Vidacic\u27s methodology is followed in order to determine the benefits that are obtained from the preprocessing steps being investigated. It is shown that performance gains are realized by using such preprocessing steps

Modeling of Large-Scale Energy Systems; Proceedings of the IIASA/IFAC Symposium on Modeling of Large-Scale Energy Systems

The problem of the seventies was energy, and the business of modeling energy systems boomed. As models became more sophisticated, and as the international and intercontinental aspects of the energy problem became clearer, the boundaries of the energy systems being modeled grew to the point where it was useful to distinguish a special category of energy models: those dealing with large-scale energy systems. Practical experience in building and applying models for large-scale energy systems has been accumulating at a rapid rate in recent years. Thus, to contribute to communicating and assimilating some of the lessons learned in the seventies about modeling large-scale energy systems, the Systems Engineering Committee of IFAC (the International Federation of Automatic Control) and the Energy Systems Program at IIASA organized an international symposium on this subject. This volume contains 43 papers given at the symposium
