Line Finder Results Related Topics Configuring Line Finder Properties Configuring Line Finder Properties - Advanced Line Finder Results Configuring Line Finder Properties Finder tools detect edges in the input images, then uses edges to generate a vectorized description called an entity. l Line Finder parameters modify the quality and quantity of edges that are generated from the input image. l Edges are detected parallel to the Y-Axis, moving through the region of interest in a negative-to-positive direction relative to the X-Axis. Minimum Line Percentage Minimum percentage of line contours that need to be matched for a line hypothesis to be con- sidered as valid.

Match Quality Percentage of edges actually matched to the found line.
Average Contrast Average contrast between light and dark pixels on either side of the found entity (point, line, or arc), expressed in grey-level values.
