A NOVEL APPROACH FOR EFFICIENT SKULL STRIPPING USING MORPHOLOGICAL RECONSTRUCTION AND THRESHOLDING TECHNIQUES
M. Ramesh · International Journal of Research in Engineering and Technology · 2014
Brain is the part of the central nervous system located in skull.For the diagnosis of human brain bearing tumour, skull stripping plays an important pre-processing role.Skull stripping is the process separating brain and non-brain tissues of the head which is the critical processing step in the analysis of neuroimaging data.Though various algorithms have been proposed to address this problem, challenges remain.In this paper a new efficient skull stripping method for magnetic resonance images (MRI) is proposed.This method adopts a two-step approach; in the first step an improved systematic application of morphological reconstructions operations is done for the brain image and in the second step, a thresholding based technique is used to extract the brain inside the skull.This paper experimented on Axial PD and FLAIR MRI brain images.
