Exploiting Voxel Correlation for Automated MRI Bias Field Correction by Conditional Entropy Minimization
Abstract. An unsupervised model-based strategy for bias field correction is proposed. We assume that information (in the sense of the information theory) in the corrupted image is...

Boundary based movement correction of functional MR data using a genetic algorithm
This paper describes a novel image registration method for movementcorrection of fMR time-series. It is important to align the fMR images in the time-series before time-dependent a...

Inhomogeneity correction of magnetic resonance images by minimization of intensity overlapping
This work presents a new algorithm (NIC; Non-uniform Intensity Correction) for the correction of intensity inhomogeneities in magnetic resonance images. The algorithm has been val...

A Unified Variational Approach to Denoising and Bias Correction in MR
Abstract. We propose a novel bias correction method for magnetic resonance (MR) imaging that uses complementary body coil and surface coil images. The former are spatially homogene...

Realistic colorization via the structure tensor
Colorization is a user-assisted color manipulation mechanism for changing grayscale images into colored ones. Several colorization algorithms have been constructed, and these meth...
