FitPathToEdges3D


Header: AVL.h
Namespace: avl
Module: Vision3DStandard

Performs a series of 1D edge detections and creates a path from the detected points.

Applications: Tracing of an object contour, whose rough location and shape is known beforehand.

Optional Outputs

The computation of following outputs can be switched off by passing value atl::NIL to these parameters: outEdges, outDeviationProfile, outHeightProfiles, outResponseProfiles, outPathSegments.
