An Intensity Correction Filtration Method for MR Images based on Energy Minimization using B-Splines
Proper analysis of MR images is critical in a variety of diagnosis the medical world. Diagnostic imaging, also
known as Medical Imaging, in this type of imaging electromagnetic radiations are used for creation of images of internal
structures of the human body so that exact diagnosis can be done. It is being increasingly and widely adopted to provide
appropriate diagnosis and treatment of various diseases with a high degree of confidence. Among all the diagnostic imaging
techniques, MR imaging systems have received the most attention.
The aim of this paper is to propose an energy minimization algorithm to correct intensity in MR images using Spline level
set approach..We do active contour segmentation by using level sets Italso involves estimation of Bias Field .We design
suitable filtering by fuzzy means and contrast mechanism for MR images. Also results have been shown using image
histogram and reconstructed image and compare with that of original one to verify the result.
