Texture is one of the most important features of medical images and reflects the spatial distribution of object.Wavelet decomposition and Fractal Browrian model were used in combination to analyze CT images of healthy people and hepatic fibrosis patients,and four vector features were obtained,which showed significant difference between normal and abnormal images.It is helpful for doctors to diagnose during early stage of hepatic fibrosis disease using CT images.
