Distorting effect of intensity rescaling on values.

Panel A: Left—Sample images from each of the five constructs described in Fig 10. Right—Same images after intensity normalization to occupy the full 8-bit dynamic range. Panel B: values for the images in Panel A at three different radii (2, 4, and 6 pixels). Note the distorting effect of intensity normalization not only on the values, but also on the relative ranking of images.面板A：左侧为图10中所述的五种构建体各自的样本图像；右侧为经强度归一化处理以覆盖完整8比特动态范围的同款图像。面板B：给出了面板A中各图像在三种不同半径（2、4、6像素）下的数值。请注意，强度归一化不仅会对数值产生畸变效应，还会改变图像间的相对排序。
