| Abstract | Hepatic tumors are tumors that grows on or in the liver. They are classified into benign and malignant tumors. Hepatocellular carcinoma is the most frequent malignant tumor in the liver. Ultrasound is the first line investigation carried out by the physician for any abnormalities in the liver. The only golden standard for detection of liver tumor is needle biopsy, but it is invasive and causes secondary infection and bleeding at that site. In this work we present a non invasive method for detection of hepatic tumors based on ultrasound images and classification is done to differentiate the tumors in the liver. The proposed method consist of three stages namely segmentation, feature extraction and classification. In the first stage the ultrasound image containing the tumor is segmented using Fuzzy C means clustering algorithm. In the second stage gray level co-occurrence matrix features are extracted from the segmented image and Haralick texture features are extracted. In the third stage consist of training the extracted features using SVM and classification is done for normal and abnormal image. The Fuzzy C means clustering combined with SVM outperforms the other classifiers with a sensitivity of 98%. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
