## Detailed Description

### template<typename _Tp>
class cv::Point_< _Tp >

template 2D point class.

The class defines a point in 2D space. Data type of the point coordinates is specified as a template parameter. There are a few shorter aliases available for user convenience. See cv::Point, cv::Point2i, cv::Point2f and cv::Point2d.
