The base class for shape models.
This base class defines a basic interface by which an shape optimizer may mathematically represent a shape and get a measurement of how well the current shape matches with a Canny edge map.

| double ShapeModel::calcDist | ( | double | p[], | |
| const Image< float > & | distMap | |||
| ) | const |
Compute distance between model (defined by p) and distance map.
Programmer's note: calcDist() is a wrapper around getDist() which does the actual distance computation. Do not overload calcDist(), overload getDist() instead.

Core of the distance computation.
This is a pure virtual function, derived classes need to implement it.
Implemented in RectangleShape, SquareShape, OctagonShape, CircleShape, and ParallelShape.
