An ASIC architecture for contour line filtering
Proposes an application-specific IC architecture for implementing a contour line filter for a real-time fingerprint recognition system. The architecture demonstrates the fact that a library-based set of data-path modules which are steered by powerful, synchronized controllers can result in real-time performance on a single chip, even for a complex image processing application. Moreover, the external frame memories required are minimized in the design by working in-place and by appropriate scheduling at the cost of little extra hardware and few additional evaluation cycles.<<ETX>>
