Arc Edge Locator Edge Filter Half-Width The filtering process attenuates peaks in the magnitude curve that are caused by noise. Filter Half-Width should be set to a value approximately equivalent to the width of the edge, in pixels, as it appears in the image. An incorrect value can cause edges to be incorrectly detec- ted. Projection Mode Projection mode used by the tool to detect edges. Projection mode is either radial or annular. Sort Results Enabled When Sort Results Enabled is set to false (default) edges are sorted in order of their location within the region of interest. When true, edges are sorted in the order of their score, from highest to lowest.
Results Logging If enabled, the results of the tool will be logged to a file. If the extension of the destination file is csv, then the log is written in csv format, which opens with Excel. If a different extension is selected, the log is written in a plain text format (similar to the ACE Sight 2 format). The size of the log file can be set (default size is 5 Mb).

To select a cus- tom sampling step, Enable must be checked.
Increasing the sampling step value reduces l the tool accuracy and decreases the exe- cution time. Reducing the sampling step can increase l the tool accuracy but will also increase the execution time.
