—A new technique for edge detection in color images corrupted by Gaussian noise is presented. The proposed method adopts a multipass processing approach that gradually reduces the noise in the R, G, and B components of the image. The prefiltering steps are specifically designed to operate in conjunction with the edge detection algorithm. They adopt two(More)
In this article we propose a peer to peer system able to permit a collaborative information exchange between public administrations. The system acts as a peer to peer network for document retrieval but in every single peer of network there is a search engine capable to index documents and able to share index information with other members
