A novel objective quality metric for image fusion is presented. The interest of our metric lies in the fact that the redundant regions and the complementary/conflicting regions are treated respectively according to the structural similarity between the source images. The experiments show that the proposed measure is consistent with human visual evaluations(More)
We address the problem of autocorrelation-based single-tone frequency estimation. It has been shown that the frequency can be estimated from the phase of the available signal’s autocorrelation with fixed lag. A large lag results in better performance but at the same time limits the estimation range. New methods have been proposed to extend the estimation(More)
A new method for single sinusoidal frequency estimation in closed-form formula is proposed. Since sinusoidal signals are narrow-banded and white noise distribution is statistically equal in the whole spectrum, a narrow-band signal extracted from the Fourier transform of the original signal can be used to approximate the noise-corrupted sinusoidal signal. A(More)
A noniterative frequency estimator is proposed in this paper. The maximum bin of fast Fourier transform (FFT) is searched as a coarse estimation, then the rational combination of three spectrum lines (RCTSL) is used as the fine estimation. Based on least square approximation in frequency domain, the combinational weights of RCTSL are found to be constants(More)
Smart home contains centralized controlled lights, Heating, Ventilation and Air Conditioning (HVAC), appliances, security locks of gates and doors and other intelligent equipment, to provide convenient, comfortable, energy efficient and secure services to users. Although many countries and organizations have designed various smart home architectures, there(More)
Under the assumption that the image information is determined mostly by the scene illumination and the objects structure, a new clutter metric, named the relative target complexity based clutter metric, for human visual systems is presented in this paper. The average intensity and the target complexity, independent of each other, are used to represent the(More)
The accurate estimation of parameters of an ultrasonic signal is essential in ultrasonic non-destructive testing (NDT). In this paper, a novel method for parameter estimation based on the Gabor transform (GT) is proposed. Firstly, the GT is used in ultrasonic signal processing in order to estimate time of flight (TOF) and center frequency (CF) by(More)
The descriptive capability of color images for a scene is better than that of grayscale images. Traditional registration methods to register color images convert them to grayscale ones, in which the registration precision is decreased due to the loss of color information. By extending some properties of the discrete Fourier transform to the quaternion(More)
