Estimates tangent using a binomial convolver.
Usage: tangentBC [options] –input <fileName>
Allowed options are :
Example:
We consider as input shape the freeman chain of the DGtal/examples/sample directory. The contour can be displayed with displayContours :
The tangents can be computed as follows:
You should obtain such a result:
contour | curvature |
---|---|
CCW oriented (index 0=blue pt) | resulting tangent (angle) |
