## Filtering options available when scanning circlesThis entry describes the use of the Geometry Algorithm options available when inspecting a circle. ## DescriptionThe following shows the default dialog box shown from Settings > Geometry Algorithm after Circle is selected from Feature type:
## Algorithms Available
## Default
## Least SquaresThis minimises the average squared error. This algorithm uses Gaussian elimination. ## Maximum InscribedThe biggest circle that fits inside all the points. The algorithm used is Tschebyscheff. ## Minimum Inscribed
## Minmax
## Elimination
## Apply
## Standard Deviations
## Filter Type
## Off
## Circular
## UPR
## Applications

If elimination or a filter is applied, the copy causes a re-evaluation as well as the new fitting. ## Requirements## See also |
