Liver Segmentation is one of the challenging tasks in detecting and classifying liver tumors from Computed Tomography(CT)*** segmentation of hepatic organ is more intricate task,owing to the fact that it possesses a sizeable quantum of *** paper proposes an algorithm for automatic seed point selection using energy feature for use in level set algorithm for segmentation of liver region in CT *** effectiveness of the method can be determined when used in a model to classify the liver CT images as tumorous or *** involves segmentation of the region of interest(ROI)from the segmented liver,extraction of the shape and texture features from the segmented ROI and classification of the ROIs as tumorous or not by using a classifier based on the extracted *** this work,the proposed seed point selection technique has been used in level set algorithm for segmentation of liver region in CT scans and the ROIs have been extracted using Fuzzy C Means clustering(FCM)which is one of the algorithms to segment the *** dataset used in this method has been collected from various repositories and scan *** outcome of this proposed segmentation model has reduced the area overlap error that could offer the intended accuracy and *** gives better results when compared with other existing *** execution in short span of time is another advantage of this method which in turns helps the radiologist to ascertain the abnormalities instantly.
