Distance Transform Gradient Density Estimation Using the Stationary Phase Approximation
we prove a novel result using the higher-order stationary phase approximation: we show convergence of the normalized power spectrum (squared magnitude of the Fourier transform) of the wave function to the density function of the distance transform gradients as the free parameter τ → 0. In colloquial terms, spatial frequencies are gradient histogram bins. Since distance transform gradients carry...
متن کاملMinimum distance estimation of stationary and non-stationary ARFIMA processes
A new parametric minimum distance time-domain estimator for ARFIMA processes is introduced in this paper. The proposed estimator minimizes the sum of squared correlations of residuals obtained after filtering a series through ARFIMA parameters. The estimator is easy to compute and is consistent and asymptotically normally distributed for fractionally integrated (FI) processes with an integratio...
متن کاملGradient-Domain Photon Density Estimation
The most common solutions to the light transport problem rely on either Monte Carlo (MC) integration or density estimation methods, such as uni& bi-directional path tracing or photon mapping. Recent gradient-domain extensions of MC approaches show great promise; here, gradients of the final image are estimated numerically (instead of the image intensities themselves) with coherent paths generat...
متن کاملDensity-functional calculations for III-V nitrides using the local-density approximation and the generalized gradient approximation
We have performed density-functional calculations for III-V nitrides using the pseudopotential plane-wave method where the d states of the Ga and In atoms are included as valence states. Results obtained using both the local-density approximation ~LDA! and the generalized gradient approximation ~GGA! for the exchangecorrelation functional are compared. Bulk properties, including lattice constan...
متن کاملMinimum Local Distance Density Estimation
We present a local density estimator based on first order statistics. To estimate the density at a point, x, the original sample is divided into subsets and the average minimum sample distance to x over all such subsets is used to define the density estimate at x. The tuning parameter is thus the number of subsets instead of the typical bandwidth of kernel or histogram-based density estimators....
