The paper presents a method for spatial fuzzy clustering (SFC) via Markov Random Fields (MRF) for the detection of brain activation regions in Functional Magnetic Resonance Imaging (fMRI) statistical parametric maps (SPMs) to improve the accuracy of

We describe an approach to the computation of the planar or volumetric maximal directional derivative (gradient) of a multispectral or hyperspectral image. We show that the planar multispectral case has an immediate solution. For the non-planar (volu

The paper describes the role of the standard wavelet decomposition in computing a fast Karhunen–Loeve transform. The standard wavelet decomposition (which we show is different from the conventional wavelet transform) leads to a highly sparse and si

This chapter introduces some aspects of visualization and the grid. Visualization --the art and science of representing data visually-- is now recognized as an equal partner in the conduct of science via the simulation and modeling paradigm. Although

Postacquisition denoising of magnetic resonance (MR) images is of importance for clinical diagnosis and computerized analysis, such as tissue classification and segmentation. It has been shown that the noise in MR magnitude images follows a Rician di

Three dimensional microscope imagery has unavoidable blurring due to out-of-focus and convolutional effects that inhibit resolution of submicron detail in biological cells. In this study, a three dimensional FIR filter is used to adaptively inverse m
