The major reasons for liver carcinoma are cirrhosis and hepatitis.  In order to  identify carcinoma in the liver abdominal CT images are used. From abdominal CT images, segmentation of liver portion using adaptive region growing, tumor segmentation from extracted liver using Simple Linear Iterative Clustering is already implemented. In this paper, classification of tumors as benign or malignant is accomplished using Rough-set classifier based on texture feature extracted using Average Correction Higher Order Local Autocorrelation Coefficients and Legendre moments. Classification accuracy achieved in proposed scheme is 90%. The results obtained are promising and have been compared with existing methods.

Current diagnosis with computed tomography (CT) imaging relies heavily on doctors’ clinical experience and it is difficult to accurately identify and localize lesions from thousands of CT images. Therefore, computer-aided diagnosis with automatic lesion extraction will be helpful for doctors in the diagnosis of liver diseases. In this paper, we proposed a new method for automatic liver lesion extraction from CT images by combining DRLSE (distance regularized level set evolution) and region growing. The method was applied in abdominal CT images with a single liver cancerous lesion and multiple hemangioma lesions at different locations. The results demonstrated the feasibility of our method for automatic lesion extraction with improved diagnostic accuracy and time efficiency.
