摘　　要：脂肪肝超声图像具有一定的纹理特征,通过对大白兔脂肪肝超声图像的特征分析,采用计算机辅助分析技术,对大白兔脂肪肝图像进行小波收缩法抑制散斑噪,然后分别从直方图,行程矩阵等进行量化指标的提取,并通过多组家兔动物实验对比分析各特征参数及实际纹理含义,从而为脂肪肝超声影像检查和病情分型提供量化依据。The ultrasonic liver images have various granular structures, With the computer assistant analysis, the rabbits liver ultrasound images were processed, by wavelet shrinkage filtering, the speckle noise of images is effectively filtered, with the methods of histogram, matrix ,8 indexes which reflect the changes of pathological were get, such as gray expectation, local correlation. At last, the rabbits of animal mode was used in the system, and the parameters gained by above methods are analyzed by statistics and pathology in order to provide computer aided analysis and recognition of rabbit fat liver degree.
