Total Variation Denoising with Spatially Dependent Regularization
Fig. 3: FA maps from the original (left), and the denoised (right) DTI data set. Magnified views of a ROI (bottom) demonstrate feature preservation in fine structures. Fig. 1: A numerical example of spatially variant regularization. (a) A numerical test image. (b) Noisy test image. (c) TV denoising with λ=20. (d) TV denoising with λ=10. (e) λ map: λ=10 (dark region) and λ=20 (bright region). (f...
متن کاملRegression With Spatially Misaligned Data
Suppose X(s) and 2(s) are stationary spatially autocorrelated Gaussian processes and Y(s) = β0 + β1X(s) + 2(s) for any location s. Our problem is to estimate the β’s, particularly β1, when X and Y are not necessarily observed in the same location. This situation may arise when the data are recorded by different agencies or when there are missing data values. A natural but näıve approach is to p...
متن کاملModeling functional data with spatially heterogeneous shape characteristics.
We propose a novel class of models for functional data exhibiting skewness or other shape characteristics that vary with spatial or temporal location. We use copulas so that the marginal distributions and the dependence structure can be modeled independently. Dependence is modeled with a Gaussian or t-copula, so that there is an underlying latent Gaussian process. We model the marginal distribu...
متن کاملRegression Modeling for Spherical Data via Non-parametric and Least Square Methods
Introduction Statistical analysis of the data on the Earth's surface was a favorite subject among many researchers. Such data can be related to animal's migration from a region to another position. Then, statistical modeling of their paths helps biological researchers to predict their movements and estimate the areas that are most likely to constitute the presence of the animals. From a geome...
متن کاملLearning a regression function via Tikhonov regularization
We consider the problem of estimating a regression function on the basis of empirical data. We use a Reproducing Kernel Hilbert Space (RKHS) as our hypothesis space, and we follow the methodology of Tikhonov regularization. We show that this leads to a learning scheme that is different from the one usually considered in Learning Theory. Subject to some regularity assumptions on the regression f...
