Q: What settings does Auto Setup use?

Auto Setup tries to determine the best circular edge in the region of interest by searching through several combinations of edge parameters in the specified search direction. The values for Minimum Edge Strength, Kernel Size, and Projection Width, and Gap are estimated to find the best edge. The quality of the edge is based on the strength of the edge along the fitted circle. The parameters that locate the strongest edge are returned as the Auto Setup results. The parameter values estimated by Auto Setup appear in the dimmed setting controls.
