The hybrid planning approach is based on a discrete plan and a forecast of continuous system behavior generated by simulation during runtime. This does not only allow an online adaptation of a previously generated plan with regard to the actual system state as well as the current environmental conditions, even the planning objectives may be adapted to newly arising needs during system operation. The planner exploits the hierarchy already present in the system model by considering hierarchical parameterizations of the system as a discrete dimension of choice. The parameterizations are proposed by a novel hierarchical multiobjective optimization, which calculates Pareto points in a bottom up fashion, taking into account the constraints imposed by lower levels of the system hierarchy on the higher ones. Evaluations of the hierarchical hybrid planner in the context of an innovative railbound transport system show that it outperforms its non-hierarchical predecessor.

We previously have introduced a novel method for registering a large amount of aerial images when camera parameters are almost unknown and no reference images are available. This paper provides two new methods, which improve our method for image registration based on virtual forces. The goal is to improve the performance of creating a contemporary overview map of a disaster area assembling several images taken by unmanned aerial vehicles (UAVs) equipped with cameras. In this paper, two new methods are introduced: a method for rotation estimation and a method for scale estimation. Both methods use fast heuristic approximation approaches and statistical methods to provide high robustness. We discuss the methods in detail and compare them to our previous approach regarding robustness and calculation speed. We can show that the new methods significantly increase the performance of the image registration process.

The algorithms and data structures developed for this approach pay particular attention to reduce memory consumption and computation power of the entire image processing, since embedded systems usually impose strong restrictions regarding those resources. The feature extraction is realized in terms of an image segmentation algorithm. The criteria of homogeneity for merging pixels and regions is provided by the color classification mechanism, which incorporates appropriate methods for defining, representing and accessing subspaces in the working color space. By doing so, pixels and regions with color values that belong to the same color class can be merged. Furthermore, pixels with redundant color values that do not belong to any pre-defined color class can be completely discarded in order to minimize computational effort. Subsequently, the extracted regions are converted to a more convenient feature representation in terms of statistical moments up to and including second order. For evaluation, the whole image processing approach is applied to a mobile representative of embedded systems within the scope of a simple real-world scenario.
