The following example from tccs/ortho/orthofair shows two 2-D sections and their local similarity.
The second dataset for computing the local similarity is specified by other=. The program performs iterations of shaping regularization. The main controling parameters are the number of iterations niter= and the smoothing radii in different dimensions rect1=, rect2=, etc. The iterations can be additionally accelerated using the eps= parameters. To suppress the output of iteration statistics on the screen, use verb=n.
