Evaluating intensity normalization on MRIs of human brain with multiple sclerosis. Med Imag Anal. 2011;15(2):267-82.M. Shah, Y. Xiao, N. Subbanna, S. Francis, D. L. Arnold, D. L. Collins, and T. Arbel, Evaluating intensity normalization on mris of human brain with multiple sclerosis...
As a result, intensity normalization plays a significant role in stan- dardizing the tissue intensity ranges across MRI volumes on which most automatic image analysis methods base their distributional assumptions. The method of Nyul et. al. [3] has become a widely used standard for in- te...

3. Intensity normalization and RAVEL correction 1. Introduction RAVEL is an R package that combines the preprocessing and statistical analysis of magnetic resonance imaging (MRI) datasets within one framework. Users can start with raw images in the NIfTI format, and end up with a variety of stati...
The intensity profile is normalized by the inferred level of the negative control cells to remove between-sample variation. Using a tissue microarray data and a pair of longitudinal biopsy samples, we demonstrated that the proposed approach can remove unwanted variations effectively and shows robust ...
► A linear procedure for intensity normalization using an α-stable distribution. ► α-stable parameters are estimated using the Maximum-Likelihood method. ► Location-scale property is used to linearly transform the voxel intensity values. ► The proposed method is compared with the widely ...
This paper describes intensity and location normalization for the improvement of the performance of a speech recognition system by using the visual information in bimodal speech recognition. In conventional speech recognition, many methods have been proposed for normalization of channel characteristics and ...
Further, we test the robustness of SPANS results to changes in SPANS parameter values and assess the impact of using various normalization approaches on downstream statistical analyses. RESULTS The normalization approach identified by SPANS differed for the two datasets. Normalization methods impacted the...
