Retrieval and comparative editing/modeling of motion data require temporal alignment. In other words, for such processes to perform accurately, critical features of motion sequences need to occur simultaneously. In this paper, we propose correlation-optimized time warping (CoTW) for aligning motion data. CoTW utilizes a correlation-based objective function for characterizing alignment. The method...
centralized trust-based collusion attack strategy in conjunction with an integer linear programming is proposed to compromise the decision of the fusion center in a two-phase energy efficient collaborative spectrum sensing (CSS) strategy, namely EE-CSS, which was discussed in [1]. The proposed strategy aims to attack only when it is likely to compromise the decision of the fusion center (FC). The...
This paper presents Correlation-optimized Time Warping (CoTW) for aligning motion sequences. The proposed method maximizes an objective function based on the correlation of the two sequences. There are several parameters involved in the process, which can be computationally optimized or manually customized. Customization can take place based on the number and/or nature of actions in the sequences...
This paper describes the Tackle system and its model-based approach for analysis and correlation of fault- and performance-related problems in wireless networks. The Tackle system is intended to operate over tactical networks to help uphold communication requirements in the network that are critical to the success of a mission. It does this by producing and reasoning over executable models that adapt...
It has been argued in recent work that correlation filters are attractive for human action recognition from videos. Motivation for their employment in this classification task lies in their ability to: (i) specify where the filter should peak in contrast to all other shifts in space and time, (ii) have some degree of tolerance to noise and intra-class variation (allowing learning from multiple examples),...
Self-organizing systems arise in many different fields. In this work we analyze data from social and biological systems. A central question is to demonstrate the presence of the determinism in time-series extracted from such systems that appear apparently not correlated but that are two good benchmarks for the study of complexity in real systems. We will apply the Kaplan test and we will define an...
Multiple-input multiple-output (MIMO) correlation matrices for high, medium, and low correlation antenna configurations are proposed. Typical microcell scenarios are adopted for simulations using an electromagnetic-based approach for full-wave field solutions. The MIMO correlation coefficients are obtained by the post-processing of these field solutions. The proposed correlation matrices are used...
