Classes
struct	Point< C, D >
	Simple Point class meant to be inherited from OpenCV point-classes. For example: Point<cv::Point2d> p. More...
struct	Index
	Class for N-dimensional index to be used e.g. with STL maps. More...
class	Histogram
	Class for N-dimensional Histograms. More...
class	HistogramSubpixel
	N-dimensional Histograms calculating also the subpixel average for max bin. More...
class	Serialization
	Class for serializing class content to/from file or std::iostream. More...

Namespaces
	alvar
	Main ALVAR namespace.

Typedefs
typedef ALVAR_EXPORT Point< cv::Point >	PointInt
	The default integer point type.
typedef ALVAR_EXPORT Point< cv::Point2d >	PointDouble
