Explicit formulae are given for the magnitude (mean square variation) of nuclear fluctuations, as a function of angle, in terms of the spins of the reacting particles. The special case of electric dipole 纬-radiation is discussed in detail....
Closed-form instantaneous cross-correlation function; ACWD: Affine characteristic Wigner distribution; KFWD: Kernel function Wigner distribution; CRWD: Convolution representation Wigner distribution; ICFWD: ICF type of Wigner distribution; CICFWD: CICF type of Wigner distribution; SNR: Signal-to-noise ra...
Use local sums to normalize the cross-correlation to get correlation coefficients. The implementation closely follows the formula from [1]: γ(u,v)=∑x,y[f(x,y)−‾‾fu,v][t(x−u,y−v)−‾t]{∑x,y[f(x,y)−‾‾fu,v]2∑x,y[t(x−u,y−v)−‾t]2...
The correlation function is closely related to the simpler convolution function:(1){formula not available us MathML}If displacements from the function averages are incorporated into Eq. 1, the result is the cross-covariance:(2){formula not available us MathML}For N data points covering the ...
Our formula reproduces the well known expression for high event densities previously published in the literature. In this paper we also present a derivation of the variance of time delay estimation that turns out to be inversely proportional to the applied time window. The derived formulas were ...
This example shows how to determine the position of the source of a wideband signal using generalized cross-correlation (GCC) and triangulation.
2. The comparative series is correlated with the next non- excluded N-element sequence using a formula (1). If the cross-correlation value is higher or equal to the intro- duced threshold R0 , the weighted average of the consid- ered subseries is calculated and taken as a new compara...
case, the first (main) term does not take into account the integral correlation of fluctuations in the displacement of the laser beam with the field of the dielectric permittivity of the medium, and the second one takes into account this correlation according to the Furutsu-Novikov formula. The...
which aimed to make algorithm most robust.And then the average in classical NCC formula was replaced by the optimization function of NCC reference value.So a novel NCC algorithm was brought forward,which was well suited for template matching of infrared image.The experimental results over real-...
