Fit a line to set of points.

minAreaRect :: Matrix (Float, Float) -> C'CvBox2D

 Fit a minimum area rectangle over a set of points

boundingRect :: Matrix (Float, Float) -> C'CvRect

 Calculate the minimum axis-aligned bounding rectangle of given points.

boundingCircle :: (ELP a ~ Double, Point2D a) => Matrix (Float, Float) -> (a, Double)

Calculate the minimum enclosing circle of a point set.

convexHull :: Matrix (Float, Float) -> Matrix (Float, Float)

Calculcate the clockwise convex hull of a point set

convexityDefects :: Matrix (Int, Int) -> [(C'CvPoint, C'CvPoint, C'CvPoint, CFloat)]
