Bibliometrics: Citation Count: 0 Having precise measurements of an indoor scene is important for several applications - e.g.augmented reality furniture placement - whereas geometric details are only needed up to a certain scale. Depth sensors provide a highly detailed reconstruction but mobile phones are not able to display and manipulate these models in real-time ... 3 April 2015 Machine Vision and Applications: Volume 26 Issue 2-3, April 2015 Publisher: Springer-Verlag New York, Inc. Bibliometrics: Citation Count: 0 In this paper, we propose a novel approach for the image-based classification of ancient coins by recognizing motifs minted on their reverse sides. Reverse motif recognition is achieved with dense sampling-based bag-of-visual-words model. As the bag-of-visual-words model lacks spatial information of visual words, we evaluate three types of tiling schemes ... Keywords: Bag of visual words (BoVWs), Rotation invariance, Spatial tiling 4 August 2014 ICPR '14: Proceedings of the 2014 22nd International Conference on Pattern Recognition Publisher: IEEE Computer Society Bibliometrics: Citation Count: 0 Unusual inactivity is caused by events, where elderly need help (e.g., falls, illness). In order to detect unusual behavior, modeling of activity results in inactivity profiles. State-of-the-Art approaches focus on temporal aspects of inactivity by only considering deviations of inactivity over time. This work proposes the use of spatial information ... Keywords: inactivity modeling, unusual behavior detection, spatio-temporal analysis 5 August 2014 ICPR '14: Proceedings of the 2014 22nd International Conference on Pattern Recognition Publisher: IEEE Computer Society Bibliometrics: Citation Count: 0 Classification of ancient coins is a substantial part of numismatic research which needs a large amount of expert knowledge due to the high number of classes to be considered. In this paper we propose an automatic image-based classification method for ancient coins to support this time-consuming and difficult process. We ... 6 April 2014 Journal on Computing and Cultural Heritage (JOCCH): Volume 7 Issue 1, February 2014 Publisher: ACM Bibliometrics: Citation Count: 0 Downloads (6 Weeks): 6,   Downloads (12 Months): 49,   Downloads (Overall): 226 Full text available: PDF Coin classification is one of the main aspects of numismatics. The introduction of an automated image-based coin classification system could assist numismatists in their everyday work and allow hobby numismatists to gain additional information on their coin collection by uploading images to a respective Web site. For Roman Republican coins, ...

Bibliometrics: Citation Count: 1 Abnormal inactivity indicates situations, where elderly need assistance. Systems detecting the need for help models the amount of inactivity using inactivity profiles. Depending on the analysis of the profiles, events (e.g. falls) or long-term changes (decrease of mobility) are detected. Until now, inactivity profiles are only used to detect abnormal ...

Bibliometrics: Citation Count: 0 In this paper we present an image-based classification method for ancient Roman Republican coins that uses multiple sources of information. Exemplar-based classification, which estimates the coins' visual similarity by means of a dense correspondence field, and lexicon-based legend recognition are unified to a common classification approach. Classification scores from both ... 9 August 2013 Personal and Ubiquitous Computing: Volume 17 Issue 6, August 2013 Publisher: Springer-Verlag Bibliometrics: Citation Count: 5 Downloads (6 Weeks): 2,   Downloads (12 Months): 12,   Downloads (Overall): 115 Full text available: PDF Current emergency systems for elderly contain at least one sensor (button or accelerometer), which has to be worn or pressed in case of emergency. If elderly fall and loose their consciousness, they are not able to press the button anymore. Therefore, autonomous systems to detect falls without wearing any devices ...

We cast the problem of vehicle tracking as ranking possible poses for each frame and connecting subsequent poses by exploiting a feasible motion model over time. As a ... Keywords: 3D Vision, 3D Vehicle Tracking, Model-Based Tracking 11 June 2013 3DV '13: Proceedings of the 2013 International Conference on 3D Vision Publisher: IEEE Computer Society Bibliometrics: Citation Count: 1 This paper presents a novel method for dense 3D reconstruction of man-made environments. Such environments suffer from texture less and non-Lambertian surfaces, where conventional, feature-Based 3D reconstruction pipelines fail to obtain good feature matches. To compensate this lack of feature matches, we exploit the semantic information available in 2D images ... Keywords: 3D Vision, Point Cloud Denisification, Dense 3D Reconstruction 12 November 2012 ACCV'12: Proceedings of the 11th international conference on Computer Vision - Volume 2 Publisher: Springer-Verlag Bibliometrics: Citation Count: 1 Falls are a major risk for the elderly and where immediate help is needed. The elderly, especially when suffering from dementia, are not able to react to emergency situations properly, thus falls need to be detected automatically. An overview of different classes of fall detection approaches is presented and a ... 13 November 2012 ACCV'12: Proceedings of the 11th international conference on Computer Vision - Volume 2 Publisher: Springer-Verlag Bibliometrics: Citation Count: 3 In this paper, we build upon the idea of using robust dense correspondence estimation for exemplar-based image classification and adapt it to the problem of ancient coin classification. We thus account for the lack of available training data and demonstrate that the matching costs are a powerful dissimilarity metric to ... 14 October 2012 3DIMPVT '12: Proceedings of the 2012 Second International Conference on 3D Imaging, Modeling, Processing, Visualization & Transmission Publisher: IEEE Computer Society Bibliometrics: Citation Count: 0 This paper presents a framework for classification and pose estimation of vehicles in videos by assuming their given 3D models. We rank possible poses and types for each frame and exploit temporal coherence between consecutive frames for refinement. As a novelty, first, we cast the estimation of a vehicle's pose ...

Bibliometrics: Citation Count: 6 We present a vision-based approach to ancient coins’ identification. The approach is a two-stage procedure. In the first stage an invariant shape description of the coin edge is computed and matching based on shape is performed. The second stage uses preselection by the first stage in order to refine the ...

Our system does not rely on pattern classification as discriminative feature extraction and classification becomes very difficult for large coin databases. This is ... 18 September 2011 ISVC'11: Proceedings of the 7th international conference on Advances in visual computing - Volume Part II Publisher: Springer-Verlag Bibliometrics: Citation Count: 0 This paper deals with the problem of computational performance of person detection using the histogram of oriented gradients feature (HOG). Our approach increases the performance for implementations of person detection using a sliding window by learning the relationship of sizes of search windows and the position within the input image. ... 19 August 2011 CAIP'11: Proceedings of the 14th international conference on Computer analysis of images and patterns - Volume Part II Publisher: Springer-Verlag Bibliometrics: Citation Count: 0 In this paper we evaluate similarity functions for histograms such as chi-square and Bhattacharyya distance for different color spaces such as RGB or L*a*b*. Our main contribution is to show the performance of these histogram-based similarity functions combined with several color spaces. The evaluation is done on image sequences of ...
