1 TUMOR BURDEN ANALYSIS ON CT BY AUTOMATED LIVER AND TUMOR SEGMENTATION RAMSHEEJA.RR Roll : No 19 Guide SREERAJ.R ( Head Of Department, CSE)

2 OBJECTIVE  Aim to the developments of the technique to constitute a computer-aided system for the fully automated integrated analysis of the liver  Study various methods of liver cancer detection  Develope a method to detect liver cancer in early

3 INTRODUCTION  Liver has many important functions  Liver cancer is 4 th most common malignancy in the world  Computed Tomography (CT) scans are a common tool for diagnosis

4 PROBLEM STATEMENT  Liver Segmentation is an important first step for Computer- Aided Diagnosis (CAD)  Difficulties associated with liver segmentation  Time consuming  Similarities to other organs

5 ADVANTAGES - AUTOMATED METHODS  The reproducibility of results  Not subjected to user interaction  Faster  Readily available  Reduce errors

6 iInput image Preprocessing Liver tumor segmentation Liver segmentation Classification Feature extraction Normal Abnormal SYSTEM ARCHITECTURE

7 LIVER SEGMENTATION[5] [3]A. M. Mharib, A. R. Ramli, S. Mashohor, R. B. Mahmood, “Survey on Liver CT image Segmentation Methods” in Artif Intell Rev 37: pp. 83-95 Springer 2012.  Segmentation techniques which are mainly automatic in nature.  Liver image segmentation techniques can be divided in two classes  semi-automatic  fully automatic methods  Graph Cuts segmentation algorithm is used

8 SEGMENTATION WITH GRAPH CUT

9 FEATURE EXTRACTION[4] [4]Statistical Texture Measures Computed from Gray Level Coocurrence Matrices Fritz Albregtsen Image Processing Laboratory Department of Informatics University of Oslo November 5, 2008  For feature extraction here use The GLCM Algorithm  Gray Level Co-occurrence Matrix  Way of extracting second order statistical texture features Energy, Entropy, Contrast, Homogeneity Correlation

10 FEATURE CLASSIFICATION[5]  Use Support Vector Machine (SVM)classifier  Binary classifier  Machine Learning Algorithm  Predict about the features  To improve classification SVM is trained by using weighted features for data classification [5]K. Kramer, L. Hall, D. Goldgof, “Fast Support Vector Machines for Continuous Data,” IEEE Transactions on Systems, Man and Cybernatics, vol. 39, no. 4, pp. 989-1001, 2009.

12 LIVER TUMOR SEGMENTATION[6]  An efficient fuzzy c-mean based segmentation algorithm to extract tumor region  FCM is a soft segmentation method which retains more information from input image than hard segmentation methods  Efficient than existing segmentation methods  To improve segmentation we can use Enhanced FCM [6]a International Journal of Computer Applications (0975 – 8887) Volume 59– No.5, December 2012 40 Performance Improvement of Fuzzy C-mean Algorithm for Tumor Extraction in MR Brain Images

13 CONCLUSION  The automated segmentation of liver is addressed first  Here segment the tumor and classifies about the image  The technique is improved significantly and the segmentation of large tumor  Reduce the number of false tumor detection
