3-D prestack migration deconvolution
An undersampled acquisition geometry and a limited recording aperture often produces migration noise (i.e., acquisition footprint) that blurs the subsurface reflectivity image. Here, we develop a prestack migration deconvolution (MD) filter that deblurs the migration image. The MD filter is applied to 3-D prestack SEG/EAGE salt data as well as 3-D marine data from Alaska. Results show that MD c...
متن کاملNonparametric deconvolution for decreasing kernels
A selection of these reports is available in PostScript form at the Faculty's anonymous ftp-Abstract A new nonparametric estimation procedure is introduced for a class of deconvolution problems where the convolution kernel is decreasing on 0; 1). The estimator is shown to be consistent and its cube root asymptotic distribution theory is established.
متن کاملInverse Kernels for Fast Spatial Deconvolution
Deconvolution is an indispensable tool in image processing and computer vision. It commonly employs fast Fourier transform (FFT) to simplify computation. This operator, however, needs to transform from and to the frequency domain and loses spatial information when processing irregular regions. We propose an efficient spatial deconvolution method that can incorporate sparse priors to suppress no...
متن کامل3-D controlled source electromagnetic interferometry by multidimensional deconvolution
Controlled Source Electromagnetic (CSEM) is an important technique in hydrocarbon exploration, because it uses the large contrast in electrical resistivity to distinguishes between water and hydrocarbons. In a shallow sea environment, the airwave that is refracted from the air-water interface dominates the recorded signal at large offsets. Therefore, the hydrocarbon detection ability of the CSE...
متن کاملHunting with Non - Gaussian Kernels
It is well known that the number of modes of a kernel density estimator is monotone nonincreasing in the bandwidth if the kernel is a Gaussian density. There is numerical evidence of nonmonotonicity in the case of some non-Gaussian kernels, but little additional information is available. The present paper provides theoretical and numerical descriptions of the extent to which the number of modes...
