. Image processing of synthetic aperture radar (SAR) images is challenging due to distributed storage of input data sets and since appropriate algorithms are complex and time-consuming. Computers able to process these data in acceptable time usually are not at user's site. Our Concurrent and Distributed Image Processing (CDIP) system overcomes these problems and provides a platform-independent, transparent...
. In line image understanding a minimal line property preserving (MLPP) graph of the image compliments the structural information in geometric graph representations like the run graph. With such a graph and its dual it is possible to efficiently detect topological features like loops and holes and to make use of relations like containment. We present a new rule based method on dual graph contraction...
. This paper presents a system for automatically selecting images in an image database to be used as illustrations of an image method or analysis process. This problem is related to the teleteaching of image processing which uses already implemented libraries of algorithms. This is in the context of a teleteaching European project. We first give a Bayesian approach to this problem, by using an image...
. A new method for lossless image compression of grey-level images is proposed. The image is treated as a set of stacked bit planes. The compressed version of the image is represented by residuals of a non-linear local predictor spanning the current bit plane as well as a few neighbouring ones. Predictor configurations are grouped in pairs differing in one bit of the representative point only. The...
. A new algorithm is presented for feature point based motion tracking in long image sequences. Dynamic scenes with multiple, independently moving objects are considered in which feature points may temporarily disappear, enter and leave the view field. This situation is typical for surveillance and scene monitoring applications. Most of the existing approaches to feature point tracking have limited...
. One major goal of active object recognition systems is to extract useful information from multiple measurements. We compare three frameworks for information fusion and view-planning using different uncertainty calculi: probability theory, possibility theory and Dempster-Shafer theory of evidence. The system dynamically repositions the camera to capture additional views in order to improve the classification...
. Nearly all three-dimensional reconstruction methods lack proper model knowledge that reflects the scene. Model knowledge is required in order to reduce ambiguities which occur during the reconstruction process. It must comprise the scene and is therefore complex, and additionally difficult to acquire. In this paper we present an approach for the learning of complex model knowledge. A (large) sample...
