We propose a model, inspired by recent artificial life theory, applied to the problem of retrieving information from a large, distributed collection of documents such as the World Wide Web. A population of agents is evolved under density dependent selection for the task of locating information for the user. The energy necessary for survival is obtained from(More)
Automation of Digital Terrain Model Generation and Man-Made Object Extraction from Aerial Images (AMOBE) is a joint project between the Institute of Geodesy and Photogrammetry (IGP) and the Institute of Communications Technology (Image Science Group) (IKT) at the Swiss Federal Institute of Technology in Zurich. In the project we develop methods and(More)
Many approaches to image understanding and object recognition employ either a single model or more than one but only one for each level of processing and processing takes place unidirectionally either bottom-up or top-down, thus restricting the flow of information between models of neighboring level to a one-way. These approaches have their limits when(More)
