3-D Image Denoising by Local Smoothing and Nonparametric Regression

Three-dimensional (3-D) images are becoming increasingly popular in image applications, such as magnetic resonance imaging (MRI), functional MRI (fMRI), and other image applications. Observed 3-D images often contain noise that should be removed beforehand for improving the reliability of subsequent image analyses. In the literature, most existing image denoising methods are for 2-D images. The...

On Nonparametric Image Registration

Image registration aims to map one image to another of a same scene. It is a fundamental task in many imaging applications. Most existing image registration methods assume that the mapping transformation has a parametric form or satisfies certain regularity conditions (e.g., it is a smooth function with continuous first or higher order derivatives). They often estimate the mapping transformatio...

On Local Smoothing of Nonparametric Curve Estimators

We begin by analyzing the local adaptation properties of wavelet-based curve estimators. It is argued that while wavelet methods enjoy outstanding adaptability in terms of the manner in which they capture irregular episodes in a curve, they are not nearly as adaptive when considered from the viewpoint of tracking more subtle changes in a smooth function. We point out that while this problem may...

Adaptive Mesh Refinement for Nonparametric Image Registration

3D image registration is a computationally extensive problem which is commonly solved in medical imaging. The complexity of the problem stems from its size and non-linearity. In this paper we present an approach that drastically reduces the problem size by using adaptive mesh refinement. Our approach requires special and careful discretization of the variational form on adaptive octree grids. I...

A Local Nonparametric Model for Simultaneous Image Segmentation and Adaptive Smoothing

Parametric and nonparametric region based active contour models have been widely used in image segmentation and showed promising results. However, since segmentation processing in these models are driven by intensity probability density functions (p.d.f.), intensity inhomogeneity and higher level of noise are always challenging problems that need to be addressed. In this paper we present a nove...
