Adaptive robust systems are required for analysis indexing and summarization of large amounts of audio-visual data. Advanced image analysis technologies are needed for next-generation description and browsing services characterized by structured object-and content-based representations. Automatic extraction of semantic information from still or moving images and the analysis of their content are necessary for automatic annotation indexing and categorization. The aim of this special issue is to bring together contributions from the latest developments in the field of object-oriented and semantic image and video analysis applications. Ten papers have been selected following the reviewing process and appear in this issue which are briefly described below. In the first paper Cavallaro and Ebrahimi tackle semantic video object extraction by interacting between color change detection and region-based processing achieving high spa tial accuracy and .
