Optical Rails [1] is a purely view-based method for autonomous track following with a mobile robot, based upon compact omnidirectional view descriptors using basis functions on the sphere. We address the most prominent points of criticism towards holistic methods for robot navigation: Dealing with occlusions and varying illumination. This is accomplished by slicing the omnidirectional view into...

This paper was originally submitted to Xinova as a response to a Request for Invention (RFI) on new event monitoring methods. In this paper, a new object tracking algorithm using multiple cameras for surveillance applications is proposed. The proposed system can detect sudden-appearance-changes and occlusions using a hidden Markovian statistical model. The experimental results confirm that our ...

Recanalisation of chronic total occlusions has remained suboptimal in the field of percutaneous coronary intervention (PCI). Hopes for a better outcome have been raised since its introduction and evolvement of new techniques, including retrograde approach. Along with conventional antegrade approaches this technique led to a success rate of more than 90% in experienced and chronic total occlusio...

introduction: an attack of acute myocardial infarction (mi) poses the threat of great damage to cardiac tissue. operative therapeutic modalities such as coronary artery bypass grafting (cabg) may enhance myocardial perfusion in high-grade coronary vasculature occlusions. it has been shown previously that low-level laser therapy (lllt) significantly reduces infarct size following induction of my...

Retinal vascular occlusive disorders constitute one of the major causes of blindness and impaired vision. There is marked controversy on their pathogeneses, clinical features and particularly their management. Recently, advances in clinical research added antivascular endothelial growth factor, corticosteroids and sustained-release implants to our armamentarium in the management of retinal vein...

In this paper we present a simplified tracking method to efficiently track people from a crowd video using the Minimum Mean Square Error (MMSE) technique. The system tracks people from a video sequence and is robust to varied lighting conditions and complex crowded scenes. The method effectively handles small occlusions and invokes a manual tracking procedure under severe occlusions. The system...

We suggest an efficient real-time method for removing occlusions when synthesizing intermediate views from two stereo images by stereo matching algorithm. The proposed method can carry out the correction of noise resulting from stereo matching, removal of occlusions to achieve high fidelity rendering, and parallel computing to achieve realtime synthesis. The proposed algorithm is compared with ...

In the context of computer vision, matching can be done using correlation measures. This paper presents the classification of fifty measures into five families. In addition, eighteen new measures based on robust statistics are presented to deal with the problem of occlusions. An evaluation protocol is proposed and the results show that robust measures (one of the five families), including the n...
