Untersuchungen zur Implementierung von Bildverarbeitungsalgorithmen mittels pulsgekoppelter neuronaler Netze

This thesis deals with the study of image processing algorithms which can be implemented by pulse-coupled neural nets. The inspiration for this choice is taken from biological image processing, which achieves with little computational effort in highly parallel processes image analysis tasks such as object recognition, image segmentation, velocity and distance estimation, etc. Conventional, serially implemented algorithms either cannot realize those tasks at all or will expend significantly more effort. Because the first stages of the visual system comprise a sensor interface, they are comparatively accessible with respect to defining their transfer or processing function. Some of those processing functions or principles are to be used in hardware implementations, with the focus on duplicating especially the highly parallel processing.Comment: Dissertation thesis, in German, with English prefac

Untersuchungen zur Modellierung und Schaltungsrealisierung von synaptischer Plastizitaet

This manuscript deals with the analysis and VLSI implementation of adaptive information processing derived from biological measurements. Specifically, models for short term plasticity, long term plasticity and metaplasticity are derived from biological measurements and implemented in CMOS circuits.Comment: Habilitation thesis, in German, with English prefac
