METODO E APPARECCHIO PER LA RIVELAZIONE DEI MARGINI DA UTILIZZARE IN UN SISTEMA DI TRATTAMENTO DELL'IMMAGINE

摘要

An edge detection apparatus and method for an image processing system are disclosed. The apparatus comprises a conversion means for converting input pixel data into tri-state valves, a matching means for obtaining inner products of tri-state valves and prespecified edge patterns and a decision means for determining the pixel data to be an edge when the pixel data is equal to the tri-state values. The edge detection apparatus can remove noise without an additional low pass filters, simplify the hardware and do real time process.
