Object tracking usually suffers from the geometrical deformations and occlusions of objects. This paper presents a new method for accurate object tracking by combining the multi-angle discriminative correlation filters and key-points under the framework of Discriminative Scale Space Tracker (DSST) tracker. Experimental results demonstrate that the proposed method can produce promising tracking results...
Stroke is the leading cause of motor-proprioceptive in stroke survivors. The stroke rehabilitation is primarily focused on the paretic arm to achieve functional tasks. Only handful studies have targeted the non-paretic arm to understand its impact on the stroke rehabilitation. Hence, to further the literature, we attempted to quantify and compare the proprioceptive loss and motor pattern in both non-paretic...
Device-to-Device (D2D) underlaying cellular network is considered to be a promising resource reuse technique. While many literatures have been investigating the air-interface performance of D2D in cellular networks from the physical and/or media access control (MAC) layers, we in this paper introduce factors about contents of information streams (upper layer factors) into the system model and conduct...
Simulation of wireless communication system is usually divided into system-level and link-level. Link-level simulation is generally used to simulate the point-to-point physical layer technologies with propagation model taken into account, which means it is based on single-cell and single terminal scenario. Multi-cell model is not often studied in link-level mainly due to its high complexity. So we...
In this paper, a new measure of correlation is introduced in undirected network. In order to get accurately degree distribution for the vertex at the end of a randomly chosen edge, we considered the information of edge, rather than just the degree distribution of node. We analysis the Enron Email Network with the three measures via degree-degree correlation, and get more information than the traditional...
Two years (2007–2008) of observational particulate matter (PM) data from ten ground-stations over eastern China, as well as collocated Aerosol Optical Depth (hereafter called AOD) derived from Moderate Resolution Imaging Spectroradiometer (MODIS), in conjunction with meteorological parameters, such as planetary boundary layer height (PBLH), relative humid (RH), temperature (TEMP), wind speed (WS),...
The consumption of watermelon relies on the guarantee of a high quality product recently. In internal and external qualities of melons, maturity is the most important factor, which is hard to evaluate. The objective of this research was to develop a feasible non-destructive procedure for ripeness detection based on the feature of acoustic impulse response. Four features/parameters were examined for...
Multi-path routing is effective to enhance network availability, by selecting multiple failure-independent paths for reaching one destination in the hope to survive individual path failures. Researchers suggest to select IP-layer topologically disjoint paths, assuming that they are failure-independent and can hardly fail simultaneously. Unfortunately, failure correlations lurking behind the IP-layer...
In this paper, we present a framework to recognize facial expressions from image sequences. Our method uses optical flow to track feature points in sequential facial frames, and computes normalized displacements of key feature points and certain standardized geometric distances to form a matrix, called facial-expression-arising-dataset (FEAD). Each FEAD represents an expression image sequence (from...
Traditional human shape classification usually adopted some key measurements, leading several problems to product ergonomic design. Multivariate analysis is able to supplement the disadvantages of traditional method. Among methods of multivariate analysis, Principal component analysis (PCA) and Factor analysis (FA) have enjoyed widespread popularity. Though both of them are to reduce the dimensions...
According to practical requirement, this paper puts forward an alarm event correlation approach basing on event driving, which considers the temporal relationship between events, and establishes several Petri net models. The experiment results show that, the approach basing on event driving to select time window can implement the alarm event correlation correctively and effectively for complex network...
Today, many wireless devices are mobile and battery powered, which means that the service duration is highly dependent on energy consumptions and battery capacities. Based on the fact that battery capacity is still limited, energy saving is an important issue in wireless communication. Many methods have been proposed to save energy in wireless communication, such as power-aware routing and sleep mode...
This study was design to test the reliability and validity of test via mobile phone based platform (MPBT) administered into potential PTSD sufferings in Mianzhu, Sichuan province, and examine the equivalence with traditional paper-and-pencil test (PPT) counterpart and gender differences. In the case of Children's Revised Impact of Event Scale (CRIES), the MPBT form had acceptable psychometric properties,...
Via jointly processing multiple (sum, azimuth- and elevation-difference) monopulse matched filter samples it is possible to extract and localize several (more than two) targets spaced more closely than the classical interpretation of radar resolution. This paper derives the Cramer-Rao lower bound (CRLB) for sampled monopulse radar data.
Based on extension theory, performance index and matter-element model of comprehensive evaluation for embedded system were established by analyzing basic characteristic, composition principle and application category of embedded system. Through calculating its comprehensive correlation degree, multiple index evaluation was formulated as the simple target decision. It obtained performance comprehensive...
This paper presents a new algorithm to estimate the cyclo-period of a poly-cyclo-stationary signal. The algorithm is essentially based on the time-varying correlation and the variability method; a calculation of the sample variance ratio as a function of the modulated noise variance visually reveals a regular pattern, from which the poly-cyclo-period is obtained. Properties of the estimation method...
Frequency-hopped OFDM (FH-OFDM) technology will provide the additional benefits of frequency diversity and inter-cell interference averaging. However, it is difficult to get the channel state information. In this paper, we propose a method of channel estimation over slow fading channels for FH-OFDM systems. In the algorithm, the channel impulse response is estimated by correlation operation, by using...
