In the last years, new clustering approaches utilizing the notion of multiple clusterings have gained attention. Two general directions — each with its individual benefits — are identifiable: (i) extraction of multiple alternative clustering solutions from one dataset and (ii) combination of multiple clusterings of a dataset into one robust consensussolution. In this paper, we propose a novel h...

The computation of the bivariate Hurst exponent constitutes an important technique to test power-law cross-correlation time series. For this objective, detrended analysis (DCCA) method represents most used one. In paper, we prove robustness DCCA method, where trend is estimated using polynomial fitting, estimate when series are corrupted by outliers observations. On other hand, give exact order...

We described a video-rate surveillance algorithm to detect and track people from a stationary camera, and to determine if they are carrying objects or moving unencumbered. The contribution of the paper is the shape analysis algorithm that both determines if a person is carrying an object and segments the object from the person so that it can be tracked, e.g., during an exchange of objects betwe...
