QIN Xiangping,FANG Yuan 2(1.Computer Center,Liuzhou People's Hospital,Liuzhou 545006,China;2.School of Electronics Information and Control Engineering,Guangxi University of Technology,Liuzhou 545006,China)  
This paper presents a method for the extraction of fatty liver ultrasound image feature.Through the extraction,one can easily analyzes ultrasound images from clinical practices in fatty liver pathology.By selecting a region of interest in a B-ultrasonic image and introducing a median filter,the quality of the image is significantly improved.The selected image region is divided into several small regional areas.By changing the selected image gray-scale and making the average gray of these small pieces,the image features can be easily identified.The difference between abnormal and normal liver are finally identifies through multi-grade gray levels contraction.Experimental results from the proposed method demonstrated its feasibility and applicability for high performance fatty liver classification.
