Measurements > Path Length

Measures the total path length of features in the current image. This path is first calculated by applying the Thin function, and then the path length is calculated with a formula similar to that used in Vossepoel and Smeulders, 1982 with end-points extended to the edge of each end pixel.

1. Measure Relative To

Choose either to extract the path either from the current image, or to use a path supplied by a memory image. Note that the Thin operation is still applied to these supplied paths. The supplied path for each feature in the current image is considered to be the paths of features in the memory image where those features overlap the feature in the current image.
