Studio-based teaching is well-established in creative disciplines such as architecture and the arts, but it has been rarely used in the teaching of IT at a tertiary level. The wider use of the studio model for teaching, originally proposed by Schon (1983), has been discussed extensively in the literature, and elements of it can be identified in teaching innovations such as problem-based learnin...

The use of the Internet for course preparation is ill served by traditional, content-based search engines. This paper describes SourceFinder, a web search engine that locates text material based on linguistic characteristics, such as reading level. Combining SourceFinder with content-based searches may allow instructors more easily to identify material relevant for their courses. We present exa...

In order to utilize the large volume of images in databases efficiently, content-based image retrieval (CBIR) has been successfully employed whereby instead of the actual images extracted feature descriptors are used. CBIR systems usually employ multidimensional indexing structures, such as the R*tree or the SR-tree to index these features and thus to speed-up the query performance. However, th...

In this chapter, we present a basic introduction of the two very important areas of research in the domain of information technology, namely, multimedia systems and content-based image retrieval. The latter is still a widely unresolved problem. We discuss some of the works done so far in content-based image retrieval in the context of multimedia systems.

The paper discusses the role of invariance in content-based image retrieval, and discusses future directions.
