Object Definition
Conformity Tolerance Maximum local deviation between the expected
model contours of an instance and the contours
actually detected in the input image.
Contrast Threshold Defines the minimum contrast needed for an edge
to be detected in the input image and used for arc
computation.
Maximum Angle Deviation Sets the maximum deviation in angle allowed for
a detected edge to be used for generating an
entity hypothesis.
Positioning Level Sets the configurable effort level of the instance
positioning process.
Subsampling Level Sets the subsampling level used to detect edges
that are used by the tool to generate hypotheses.
Results
Object Definition
Instance Index of the result instance (numbered from 0)
Arc X The X coordinate of the point midway between the
ends of the found arc
Arc Y The Y coordinate of the point midway between the
ends of the found arc
Radius The radius of the found arc, Arc X and Arc Y being
the center of the circular arc described by the
found arc
Opening The angle of the found arc
Rotation The rotation of the region of interest
Average Contrast Average contrast between light and dark pixels on
either side of the found arc, expressed in grey-
level values.
Fit Quality Normalized average error between the calculated
arc or line entity and the actual edges matched to
the found entity.
Match Quality Percentage of edges matched to the found arc.
