Detailed Description

This functor extracts a functional border description from a borderPoint list.

Therefore it divides the 2D-space into radial segments of equal size, originating from the given "center". Then it evaluates some function for the borderPoints, that lie within each segment. The result is stored in a lti::dvector.

The starting segments angle can be specified by the parameter "orientation". There are two methods of operation: "area" and "distance". The "area" method calculates the area proportion within each segment, normalized with the total area. The "distance" method calulates either the minimum, maximum or the average distance to the center point within a segment. This is specified by the "distanceType" parameter.
