The elderly person’s life is almost full of hazards. Especially, the fall risk is one of the problems caused by the elderly and the people using prostheses. This paper aims to develop a fall prediction system on smartphones. The proposed App system can record users’ gait data sets with which their gait statuses regarding stability and symmetry are analyzed. A high-level fuzzy Petri net model is used...
With the widely application of high-resolution remote sensing images, its classification has attracted a lot of attention. Usually, some different categories share common patterns, which make these categories look similar. This makes the classification of such categories a challenging task. In this paper, we propose a novel dictionary learning based bilayer classification algorithm to solve this problem...
With the widely application of high-resolution remote sensing images, its classification has attracted a lot of attention. Most classification methods focus on various combination of features and ignore the similarities between different categories. In this paper we present a modification by combining ScSPM [1] with a dictionary learning method DL-COPAR [2], which separates the particularity and commonality...
In this paper, we propose a framework GP-MRF, which combines Gaussian processes (GPs) and Markov random field (MRF) for accurate classification of hyperspectral remote sensing image (HSI) data. This method exploits the relationship among adjacent pixels and integrates it into spectral information to obtain spectral-spatial classification. This framework consists of two steps. Firstly, a GP classifier...
After extracting the candidate region from an image, it is necessary to take a kind of technology to determine whether the split target is a pedestrian. By analysis and feature extraction to segmentations of pedestrian candidate region, the classification of pedestrians has been studied. The pedestrian classifier of the SVM (Support Vector Machines) has been trained with pedestrian's typical characteristics...
The establishment of non-linear model of piezoelectric actuator is a key link of the nano-scale micro-displacement measurement and control. Due to the inherent nonlinearity and the influence of load pressure, piezoelectric actuator always causes position error in the open-loop system and instability in the closed-loop system. Based on the experiment of creep characteristics, the effect of driven voltage...
Current methods of assessing psychopathology depend almost entirely on verbal report (clinical interview or questionnaire) of patients, their family, or caregivers. They lack systematic and efficient ways of incorporating behavioral observations that are strong indicators of psychological disorder, much of which may occur outside the awareness of either individual. We compared clinical diagnosis of...
Most of the previous audio-watermarking schemes are robust to common signal-processing attacks, but show severe problems when faced with desynchronization attacks. To solve the problems associated with these approaches, we propose an audio-watermarking scheme based on support-vector-machine (SVM) theory to protect against desynchronization attacks by using audio statistics characteristics and a synchronization...
