Analog VLSI Circuits for the Perception of Visual Motion

Beschreibung

Although it is now possible to integrate many millions oftransistors on a single chip, traditional digital circuittechnology is now reaching its limits, facing problems of cost andtechnical efficiency when scaled down to ever-smaller featuresizes. The analysis of biological neural systems, especially forvisual processing, has allowed engineers to better understand howcomplex networks can effectively process large amounts ofinformation, whilst dealing with difficult computationalchallenges. Analog and parallel processing are key characteristics ofbiological neural networks. Analog VLSI circuits using the samefeatures can therefore be developed to emulate brain-styleprocessing. Using standard CMOS technology, they can be cheaplymanufactured, permitting efficient industrial and consumerapplications in robotics and mobile electronics. This book explores the theory, design and implementation ofanalog VLSI circuits, inspired by visual motion processing inbiological neural networks. Using a novel approach pioneered by theauthor himself, Stocker explains in detail the construction of aseries of electronic chips, providing the reader with a valuablepractical insight into the technology. Analog VLSI Circuits for the Perception of VisualMotion: * analyses the computational problems in visual motionperception; * examines the issue of optimization in analog networks throughhigh level processes such as motion segmentation and selectiveattention; * demonstrates network implementation in analog VLSI CMOStechnology to provide computationally efficient devices; * sets out measurements of final hardware implementation; * illustrates the similarities of the presented circuits with thehuman visual motion perception system; * includes an accompanying website with video clips of circuitsunder real-time visual conditions and additional supplementarymaterial. With a complete review of all existing neuromorphic analog VLSIsystems for visual motion sensing, Analog VLSI Circuits for thePerception of Visual Motion is a unique reference for advancedstudents in electrical engineering, artificial intelligence,robotics and computational neuroscience. It will also be useful forresearchers, professionals, and electronics engineers working inthe field.
