Topic : Fuzzy Membership Function Based Localization of Spinal Cord in Computer Tomographic Images

Authors:K.Malathy ||

Abstract:Automatic segmentation of bone in computed tomography (CT) images is critical for the implementation of computer-assisted diagnosis which has increasing potential in the evaluation of various spine disorders. Of the many techniques available for delineating the region of interest (ROI), active contour methods (ACM) are well-established techniques that are used to segment medical images. The project presents a methodology for automatic contour initialization in ACM and demonstrates the applicability of the method for medical image segmentation from spinal CT images. Initially, a set of feature markers from the image is extracted to construct an initial contour for the ACM. A fuzzified corner metric, based on image intensity, is proposed to identify the feature markers to be closed by the contour. A concave hull based on α shape is constructed using these fuzzy corners to give the initial contour. The results show the method's robust performance in the presence of different noise levels.
