An algorithm for automatic, noise robust segmentation of moving objects in image sequences is presented. Such algorithms are required for object–based coding techniques like the upcoming ISO/MPEG–4 standard. In a first step, a mask of changed image areas is estimated by a local thresholding relaxation technique. Then, areas of uncovered background are(More)
An algorithm for automatic, noise robust 2D shape estimation of moving objects in video sequences considering a moving camera is presented. Such algorithms are required for object–based coding techniques like the upcoming ISO/MPEG–4 standard. In a first step, a possibly apparent camera motion is estimated and compensated. By the second step, a possibly(More)
In this paper we describe an interactive video object segmentation tool developed in the framework of the ACTS-AC098 MOMUSYS project. The Video Object Generator with User Environment (VOGUE) combines three different sets of automatic and semi-automatic tools (spatial segmentation, object tracking and temporal segmentation) with general purpose tools for(More)
This paper discusses the usefulness of a partition-based image representation in the context of user-assisted segmentation, and compares it with the two other most common image representations in this framework: pixel-based and transition-based. Partition-based image representations allow user-interaction at the region level, which is a very natural and(More)
Modern in-car infotainment and navigation systems will incorporate features from the automotive electronics as well as from the consumer electronics. These domains have very different innovation cycles, with effects on the hardware and software development process. The " Innovation Cycle Dilemma " refers to the difficulty in integrating both domains. This(More)
