Figure 4.1r Scale space image with 12 levels and step size 
ao=1 (right stereo partner) 
In the fine scale levels striking differences between two signals 
are recognized resulting from geometric and radiometric scale 
differences between two images. These influences are also 
easily observable on the coarser scale. The roughness images of 
the corresponding image pair can be seen in figures 4.21 and 
4.2r for the finer scale levels and in figures 4.31 and 4.3r for the 
coarser scale levels o= 8-13.
