This paper introduces a modified algorithm of singularity detection based on modulus maxima for through-wall radar (TWR) targets detection. By tracking the wavelet transform modulus maxima (WTMM) at fine scales, singularities can be detected, and the important information of human target is also selected. According to the singularities of TWR A-scan signal, it can be commendably given prominence to...
For the multisensor systems with same measurement matrix, when the noise variances are unknown, an information fusion noise variance estimator is presented using the correlation method and least squares fusion criterion. It has the consistence and reliability of accuracy. Further, a self-tuning weighted measurement fusion Kalman filter based on the information matrix is presented. By using the dynamic...
We address the problem of recognizing, in dynamic meetings in which people do not remain seated all the time, the visual focus of attention (VFOA) of seated people from their head pose and contextual activity cues. We propose a model that comprises the VFOA of a meeting participant as the hidden state, and his head pose as the observation. To account for the presence of moving visual targets due to...
The covariance region descriptor recently proposed in [1] has been proved robust and versatile for a modest computational cost. The covariance matrix enables efficient fusion of different types of features, where the spatial and statistical properties as well as their correlation are characterized. The similarity of two covariance descriptor is measured on Riemannian manifolds. Relying on the same...
A new algorithm is proposed for track initiation in a distributed passive sensor network. The algorithm is formulated using a newly defined fuzzy synthetic closeness function in which the correlations between the set of measurements and targets are reflected. First of all, the algorithm detects targets through searching the globe extreme points of the fuzzy synthetic closeness function using the steepest...
An algorithm for a rotation invariant template matching method based on correlation value circular projection target tracking algorithm is proposed in this paper. This algorithm projects the model image as circular and gets the radius and the sum of the same radius pixel value. In order to improve the matching speed and get the illumination invariance, the traditional correlation method is combined...
