1) ratio of dissimilitude
相异率
1.
The original MRI image and the MRI image that compressed by JPEG were programmed, the optical impression and ratio of dissimilitude of these images are showed, the result indicated that the edges and the noises in the MRI image would be smoothed and lost after compressing by the JPEG method.
简要分析了有损JPEG压缩算法和几种经典的边缘提取算法;经对原始的和有损JPEG压缩的MRI图像的编程实验,分析了图像边缘的视觉效果和相异率,说明MRI图像经有损JPEG压缩后对图像的边缘和噪声都有所平滑改变和丢失;由于有损JPEG具有低通滤波的性质,所分析的几种经典的边缘提取算法具有高通滤波的性质,使MRI图像的边缘和噪声在JPEG压缩前后的差异随门限值的增大而变小。
2) mutual different rate (MDR)
相互变异率
3) quadrature resistivity
异相电阻率
4) Relative mutation rate
相对变异率
5) similarity and diversity percentage
相似相异百分率
6) permeability phase-out zone
渗透率异相带
