The feature parameters of the ridge include the parameters defining the shape of the path of the ridge
Grahic Jump Location
Physical part selected for 3D scanning. A region of interest, containing a ridge, is indicated.

Parameters (q) for the pattern G(q)
Grahic Jump Location
To prepare for the distance computation, points have been sampled from the ridge pattern (thick points); these are shown adjacent to the digitized sample F (thin points)
