Abstract: Liver is the largest internal organ in human body. It lies under right ribs just beneath right lung, shaped like a pyramid and divided into four different lobes. It is the only internal organ which has the property of regeneration of lost tissue. It plays major role in metabolism, emulsification of lipids and stores nutrients. Accurate segmentation of liver is still a challenge due to differences in intensity, contrast and texture. In this paper we have proposed a method to extract the liver from computed tomography DICOM images using seed point in such a way that it will always be present within the liver. This method assists radiologists in accurate segmentation of liver which in turn helps the patients.
