肝纤维化CT图像的小波变换和布朗分形模型分析

Wavelet Transform and Fractal Brownian Model of Hepatic Fibrosis CT Images

图像的纹理反映物质的空间分布特性 ,是医学图像的重要特征之一。本研究通过对正常和异常CT图像进行小波变换和布朗分形模型分析 ,得到了

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.
