The purpose of this paper is to present a practical dynamic model of fiber optic gyro (FOG). In terms of the sampled data, theoretically and practically provide the optimal engineering solutions. Based on ARMA(p, q) modeling, engineering application methods can be ameliorated. By segmenting the composition in the form of signals, the model is more reasonable and reliable. Approach mentioned in the...
In this paper, a method for lighting directions estimation of the uniform texture images has been proposed. The proposed algorithm does not require training database, and only utilizes one input image for estimating the lighting directions. By detecting the largest direction of the brightness changes of the input image, the azimuth angle of the light source can be estimated. The slant angle is estimated...
In short burst communication system, a joint rotational periodogram averaging (RPA) and demodulation soft information carrier estimation algorithm is proposed in this paper. Firstly, the coarse carrier estimation is carried out with periodogram averaging method after that the pilot sequence is rotated with different frequency offsets. Then, further fine carrier estimation is done by stepwise searching...
In the study of leakage current signal of insulators, warning value is mainly found the when the insulators occur flashover. However in the actual study, due to contamination of insulators leakage current signal making a lot of noise, the premise of the in-depth study on the leakage current signal is extracted out clean signal without interference. In view of the broader application of signal de-noising...
Head pose is an important indicator of a person's attention, gestures, and communicative behavior with applications in human computer interaction, multimedia and vision systems. In this paper, we present a novel head pose estimation system by performing head region detection using the Kinect [2], followed by face detection, feature tracking, and finally head pose estimation using an active camera...
A background estimation system, which integrates pixel-level features with a region-level one and combines short-term and long-term analysis of videos in outdoor illumination variations, is proposed for accurate foreground detection. Firstly, we discuss autocorrelation-based features for identification of the presence of foreground and outdoor illumination variations in short-term sequences, and propose...
Two-Step Weighted Least Squares (TSWLS) method (or the Chan method) is a classical TDOA-Based localization algorithm. We find that the Chan method will yield exceptionally large localization error if the target node is near the center of a circle formed by the anchor nodes. We name such a phenomenon Lost at the Center of a Circle (LCC). It is shown that LCC has no connection with the Geometric Dilution...
This paper deal with the problem of direction-of-arrival (DOA) estimation with a polarization sensitive array. The proposed DOA estimation method is based on a sparse representation of polarization sensor measurements with an overcomplete basis composed of samples from the polarization sensitive array manifold. It enforces sparsity by ??1-norm to obtain a sharp amplitude estimate of the sparse solution...
