this paper represents a new region-based active contour model that can be used to segment images with intensity non-uniformity and high level noise. the main idea of our proposed method is to use gaussian distributions with different means and variances with incorporation of intensity non-uniformity model for image segmentation. in order to integrate the spatial information between neighboring ...

OBJECTIVES Associations between cardiovascular mortality and air pollution and noise together were investigated. METHODS Data from the ongoing Netherlands Cohort Study on Diet and Cancer (120,852 subjects; follow-up 1987-1996) were used. Cox proportional hazard analyses were conducted for the association between cardiovascular mortality and exposure to black smoke, traffic intensity on the ne...

Noise Estimation, Noise Reduction and Intensity Inhomogeneity Correction in MRI Images of the Brain Michael Eziashi Osadebey, Ph.D. Concordia University, 2015 Rician noise and intensity inhomogeneity are two common types of image degradation that manifest in the acquisition of magnetic resonance imaging (MRI) system images of the brain. Many noise reduction and intensity inhomogeneity correctio...
