Inset Distances
Aim:
The task is to devise an algorithm that would compute the distance between ridges.
Input:
A set of images with variable positions of the object as in the picture below:
Output:
Detected ridges in the image with the computed distance between them (the width of a gap):
Hints:
As the position of ridges slightly changes, think of a way to locate the ridges without using the Template Matching technique. You could use some other part of the image to find its alignment. Using the Region Analysis, it is possible to determine the location of holes and, based on this information, to create a local coordinate system.
