A space-variant representation of images is of great importance for active vision systems capable of interacting with the environment. A precise processing of the visual signal is achieved in the fovea, and, at the same time, a coarse computation in the periphery provides enough information to detect new saliences on which to bring the focus of attention. In this work, different techniques to i...

The X.500 directory provides a powerful mechanism for storing and retrieving information about objects of interest. To interpret the information stored in the directory, the schema must be known to all the components of the directory. The rapid increase in the number of schemas and the relatively slow pace of standardization and subsequent publication has given rise to the challenge of making t...

This paper describes the OKE Corral, an active network environment which allows third-party active code to control the code organisation at any level of the network node. This includes the kernel. The underlying code is structured much like components in a ’Click’-router that may be connected or disconnected at runtime. Using this, active packets are able to reconfigure predefined components in...
