Tutorial 2: FOOM – Functional and Object Oriented Methodology: An Integrated Approach

High Resolution satellite Imagery is an important source for road network extraction for urban road database creation, refinement and updating. However due to complexity of the scene in an urban environment, automated extraction of such features using various line and edge detection algorithms is limited. In this paper we present an integrated approach to extract road network from high resolution space imagery. The proposed approach begins with segmentation of the scene with Multi-resolution Object Oriented segmentation. This step focuses on exploiting both spatial and spectral information for the target feature extraction. The road regions are automatically identified using a soft fuzzy classifier based on a set of predefined membership functions. A number of shape descriptors are computed to reduce the misclassifications between road and other spectrally similar objects. The detected road segments are further refined using morphological operations to form final road network, which is then evaluated for its completeness, correctness and quality. The experiments were carried out of fused IKONOS 2 , Quick bird ,Worldview 2 Products with fused resolution’s ranging from 0.5m to 1 m. Results indicate that the proposed methodology is effective in extracting accurate road networks from high resolution imagery.

Abstract In the global market of the 21st century the time-to-market reduction is an imperative statement for every automotive company. Automobile manufacturers must continue their efforts in order to exceed the customers’ expectations for improved quality during the engineering phase of new vehicles. Two available technological methods to meet that goal are simulation and bench testing. These enable advanced engineering and testing departments of the automotive industry to reduce development time and costs, identify weak spots of components or systems before volume parts are ever produced. This paper presents an integrated approach described as object-oriented simulation and testing for vehicle driveline vibrations. It is also aimed to investigate transmission rattle, which is a well-known classical noise-vibration-harshness (NVH) phenomenon. It affects the vehicle ride and comfort resulting in customer satisfaction. The target of this combined analysis, simulation and testing, is to investigate the dynamic interaction of all driveline components by exciting them with the angular speed irregularities of a 4-cylinder diesel engine. A new benefit with this approach is the ability for fine-tuning of the vehicle driveline. They also contribute to reduction of the time-to-market bottleneck during design and the development process. Also highlighting new methods to particularly research the transmission rattle phenomenon. The application of the previously mentioned tools in a real vehicle rattling case is presented to show the potential of this approach.
