Most systems that aspire to run in real-time use a fast segmentation stage that considers the whole image, and then a more costly stage for classification. In this paper we present a novel approach to segment moving objects from images taken with a moving camera. The segmentation algorithm is based on a special representation of optical flow, on which u-disparity is applied. The u-disparity is used to indirectly find and mask out the background flow in the image, by approximating it with a quadratic function. Robustness in the optical flow calculation is achieved by contrast content filtering. The algorithm successfully segments moving pedestrians from a moving vehicle with few false positive segments. Most false positive segments are due to poles and organic structures, such as trees. Such false positives are, however, easily rejected in a classification stage. The presented segmentation algorithm is intended to be used as a component in a detection/classification framework.","PeriodicalId":386189,"journal":{"name":"IEEE Proceedings.

One aspect which hampers the introduction of these technologies is context awareness. In this paper we develop and evaluate a road scene monotony detector. The detector can be used to give context awareness to fatigue detection tools to minimise false positives. The approach could also be used by road makers to quantify monotony on fatigue prone stretches of road. The detector uses MPEG compression to measure the change in information content of the road scene over time. We show that the detector correlates highly with human identified monotonous scenes. The technique is consistent over time and applicable for day and night operation. The compression is augmented with lane tracking data to distinguish between otherwise difficult cases. The detector is integrated into a fatigue management driver assistance system.","PeriodicalId":386189,"journal":{"name":"IEEE Proceedings.

The acquisition of accurate environment parameters is crucial for robot path planning. In this article, the idea of mission-plan is introduced on the basis of the path plan. The whole mission is decomposed into several sub-missions during the mission modeling process. And one case-based mission-planning method (CBMP) is applied to filter and optimize the robot's geometric and kinetic parameters for properly configuration.

Incorporating a spatial restriction in the height direction of road scenes into the recursive computation of correlation measures, the proposed method efficiently provides dense disparity measures. A pair of cameras just has to be weakly calibrated due to the non-metric formulation. We also implement our stereo method on a newly developed onboard LSI, which has a dedicated architecture for practical automotive use and realizes more than BOM disparity estimations per second. Furthermore, we apply our method to a side collision warning system, which detects approaching objects such as pedestrians and bicycles. Through experiments we demonstrate the efficiency of our stereo method in road environments.","PeriodicalId":386189,"journal":{"name":"IEEE Proceedings.

Usually these approaches are on a rather quantitative level. A knowledge-based approach as presented here has the advantage of a better comprehensibility and allows for formulating and using common sense knowledge and traffic rules while reasoning. In our approach a knowledge base is the central component for higher-level functionality. A qualitative mapping module abstracts from the quantitative data and stores symbolic facts in the knowledge base. The knowledge-based approach allows for easily integrating and adjusting background knowledge. Higher-level modules can query the knowledge base in order to evaluate the situation and decide what actions to perform. For the evaluation of the approach a prototype was developed in order to simulate traffic scenarios. In experiments behavior decision was applied for controlling the vehicle and its gaze.","PeriodicalId":386189,"journal":{"name":"IEEE Proceedings.

This method applies Gaussian mixture models (GMM) to the phase information obtained from a microphone array. The individual Gaussian component of a GMM represents some general location-dependent phase difference distribution between two microphones. These distributions are effective in modeling the speaker's location. The relation between geometry of microphone array and frequency band is taken into consideration to avoid aliasing problems. The proposed approach provides an accurate estimation even in near-field, noisy and complex vehicle environment. Moreover, it performs well not only in non-line-of-sight cases, but also in the conditions that the speakers are aligned in a direction to the microphone array with difference distances. Experiments are conducted in a mini-van vehicle and the results show that the proposed method outperform the popular technique multiple signal classification method (MUSIC) in different SNR cases.","PeriodicalId":386189,"journal":{"name":"IEEE Proceedings.
