A Review of Methods for Correction of Intensity Inhomogeneity in MRI
IEEE Transactions on Medical Imaging, 2007Medical image acquisition devices provide a vast amount of anatomical and functional information, which facilitate and improve diagnosis and patient treatment, especially when supported by modern quantitative image analysis methods. However, modality specific image artifacts, such as the phenomena of intensity inhomogeneity in magnetic resonance images

A Level Set Approach to Image Segmentation With Intensity Inhomogeneity
IEEE Transactions on Cybernetics, 2016It is often a difficult task to accurately segment images with intensity inhomogeneity, because most of representative algorithms are region-based that depend on intensity homogeneity of the interested object. In this paper, we present a novel level set method for image segmentation in the presence of intensity inhomogeneity.

Retrospective correction of intensity inhomogeneities in MRI
IEEE Transactions on Medical Imaging, 1995Medical imaging data sets are often corrupted by multiplicative inhomogeneities, often referred to as nonuniformities or intensity variations, that hamper the use of quantitative analyses. The authors describe an automatic technique that not only improves the worst situations, such as those encountered with magnetic resonance imaging (MRI) surface ...

Segmentation of MR images with intensity inhomogeneities
Image and Vision Computing, 1998A statistical model to segment clinical magnetic resonance (MR) images in the presence of noise and intensity inhomogeneities is proposed. Inhomogeneities are considered to be multiplicative low-frequency variations of intensities that are due to the anomalies of the magnetic fields of the scanners.

Parametric estimate of intensity inhomogeneities applied to MRI
IEEE Transactions on Medical Imaging, 2000This paper presents a new approach to the correction of intensity inhomogeneities in magnetic resonance imaging (MRI) that significantly improves intensity-based tissue segmentation. The distortion of the image brightness values by a low-frequency bias field impedes visual inspection and segmentation.

Image Segmentation for Intensity Inhomogeneity in Presence of High Noise
IEEE Transactions on Image Processing, 2018Automated segmentation of fine objects details in a given image is becoming of crucial interest in different imaging fields. In this paper, we propose a new variational level-set model for both global and interactive\selective segmentation tasks, which can deal with intensity inhomogeneity and the presence of noise.
