Edge Locator Filter Half Width The filtering process smoothes peaks in the magnitude curve that are caused by noise. Edge 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 detected. Sort Results Enabled When Sort Results Enabled is set to false (default) edges are sorted in the order of their loc- ation within the region of interest. When set to true, edges are sorted in the order of their score, from highest to lowest. By default, Sort Results is not enabled and edges are output in the same left to right order as they appear on the projection curve.
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).

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 can also increase the execution time.
