Arc Edge Locator ACEUser's Guide, 3.6.x, 18316-000 Rev A Page 386 Object Definition Elapsed Time The Elapsed Time is the total execution time of the Arc Edge Locator. Elapsed Time is not visible in the results grid, but it is displayed at the bottom left of the Display window after each iteration of the Arc Edge Locator. Instance The identification number of the edge. Enabling Edge Sort affects the order of edge numbering. Frame/Group The frame or group to which the result belongs. Edge X The X coordinate of the center point for each edge segment. Edge Y The Y coordinate of the center point for each edge segment. Edge Score Score is the calculated score, between 0 and 1, for each edge.
The score is calculated according to the defined constraint functions. If both Position and Magnitude constraints are enabled, each con- straint accounts for 50% of the score. Radius Radius of the edge. Position Score Score, between 0 and 1, for the edge, calculated according to the Position Constraint function. Magnitude Magnitude indicates how well the region of interest arc matches the found arc. This will be negative if the found arc is a reflection of the region of interest arc. The Magnitude of the edge indicates its peak value in the magnitude curve. Magnitude Score Score, between 0 and 1, for the edge, calculated according to the Magnitude Constraint function.
