Generalized Method for Sampling Spatially Correlated Heterogeneous Speckled Imagery
نویسندگان
چکیده
This paper presents a general result for the simulation of correlated heterogeneous targets, which are present in images corrupted by speckle noise. This technique is based on the use of a correlation mask and Gaussian random variables, in order to obtain spatially dependent Gamma deviates. These Gamma random variables, in turn, allow the obtainment of correlated K deviates with specified correlation structure. The theoretical properties of the procedure are presented, along with the corresponding algorithm.

Gap-Filling of Landsat 7 Imagery Using the Direct Sampling Method
The failure of the Scan Line Corrector (SLC) on Landsat 7 imposed systematic data gaps on retrieved imagery and removed the capacity to provide spatially continuous fields. While a number of methods have been developed to fill these gaps, most of the proposed techniques are only applicable over relatively homogeneous areas. When they are applied to heterogeneous landscapes, retrieving image fea...
متن کاملImproving Estimation in Speckled Imagery
We propose an analytical bias correction for the maximum likelihood estimators of the G0 I distribution. This distribution is a very powerful tool for speckled imagery analysis, since it is capable of describing a wide range of target roughness. We compare the performance of the corrected estimators with the corresponding original version using Monte Carlo simulation. This second-order bias cor...
متن کاملA Bayesian Approach to Inference and Prediction for Spatially Correlated Count Data Based on Gaussian Copula Model
Gaussian Copula has been successfully applied in spatially correlated count data due to its ability to completely model the high-dimensional dependence. In this article, we develop a Bayesian method to fulfill both parameter estimation and spatial prediction for spatially correlated count data set. A MCMC scheme (MetropolisCHastings Algorithm plus rejection sampling) is adopted to iteratively u...

In the present study, analytical solutions are obtained for two-dimensional advection dispersion equation for conservative solute transport in a semi-infinite heterogeneous porous medium with pulse type input point source of uniform nature. The change in dispersion parameter due to heterogeneity is considered as linear multiple of spatially dependent function and seepage velocity whereas seepag...
متن کاملObject-Based Classification of UltraCamD Imagery for Identification of Tree Species in the Mixed Planted Forest
This study is a contribution to assess the high resolution digital aerial imagery for semi-automatic analysis of tree species identification. To maximize the benefit of such data, the object-based classification was conducted in a mixed forest plantation. Two subsets of an UltraCam D image were geometrically corrected using aero-triangulation method. Some appropriate transformations were perfor...
