19. Our General Motivations Intelligent computer To simulate what people can and, to do what people cannot, to create what people can or cannot imagine 10 th dimension in creating new media, new knowledge and innovative computer Vision capability The understanding of single images and their relations with other images Visual information is the most important but most difficult element

20. Our General Motivations Information and knowledge Information can be useful only if they are located and organised. People’s need for information remains the same, however “the form in which the information is expressed and the methods that are used to manage it are greatly influenced by technology, and this creates change” (Arms 2000) People’s need for information remains the same, however “the form in which the information is expressed and the methods that are used to manage it are greatly influenced by technology, and this creates change” (Arms 2000) Digital technology means it is even easier to produce, distribute and store materials Digital technology means it is even easier to produce, distribute and store materials Information retrieval?

26. Approach of the Study adopt patterns of use and patterns of computation as the leading principles. adopt patterns of use and patterns of computation as the leading principles. follow the data as they flow through the computational process and consider alternative processes with the same position in the flow follow the data as they flow through the computational process and consider alternative processes with the same position in the flow concentrate on generic computational methods but look at applications too concentrate on generic computational methods but look at applications too
