# Inliers and Outliers

The LineMax tool defines found edge points as either inliers or outliers:

- The tool identifies an edge point as an inlier if it is included in the fit for one of the line results
- Edge points that are not consistent with line-fitting parameters are identified as outliers.

The edit control for a LineMax tool can display the gradient direction of each found edge point along with a color to represent whether it is an inlier or outlier:

A LineMax tool can be configured to generate information about all edge results in the current image without finding any lines by setting the number of line segments to locate to zero. See the topic LineMax Edit Control for more information.
