Openv2.1基本数据类型

1、Point_

template<typename _Tp> class Point_

{_Tp x, y;}

可使用的运算：

pt1 = pt2 + pt3;

pt1 = pt2 - pt3;

pt1 = pt2 * a;

pt1 = a * pt2;

pt1 += pt2;

pt1 -= pt2;

pt1 *= a;

double value = norm(pt); // L2 norm

pt1 == pt2;

pt1 != pt2;

预定义：

 typedef Point_<int> Point2i;
 typedef Point2i Point;
 typedef Point_<float> Point2f;
 typedef Point_<double> Point2d;

Point3_（3维点类）

2、Size_

 _Tp width, height;
 typedef Size_<int> Size2i;
 typedef Size2i Size;
 typedef Size_<float> Size2f;

3、Rect_

 _Tp x, y, width, height;
 typedef Rect_<int> Rect;

运算：

•  (平移)
•  (放缩)
• rect = rect1 & rect2 (矩形交集)
• rect = rect1 | rect2 (包含两矩形的最小区域 )
• rect == rect1, rect != rect1 (比较)

4. RotatedRect

Point2f  center;  Size2f  size;  float  angle;

5、Vec

 typedef Vec<uchar, > Vec2b;
 typedef Vec<uchar, > Vec3b;
 typedef Vec<uchar, > Vec4b;

 typedef Vec<short, > Vec2s;
 typedef Vec<short, > Vec3s;
 typedef Vec<short, > Vec4s;

 typedef Vec<int, > Vec2i;
 typedef Vec<int, > Vec3i;
 typedef Vec<int, > Vec4i;

 typedef Vec<float, > Vec2f;
 typedef Vec<float, > Vec3f;
 typedef Vec<float, > Vec4f;
 typedef Vec<float, > Vec6f;

 typedef Vec<double, > Vec2d;
 typedef Vec<double, > Vec3d;

 typedef Vec<double, > Vec4d;
 typedef Vec<double, > Vec6d;

6、Scalar_

 template<typename _Tp> class Scalar_ : public Vec<_Tp, >
 {
 Scalar_(_Tp v0, _Tp v1, _Tp v2=, _Tp v3=);
     Scalar_(const CvScalar& s);
     Scalar_(_Tp v0);
     static Scalar_<_Tp> all(_Tp v0);
 }

 typedef Scalar_<double> Scalar;

7、Range

 class Range
 {
 public:
     Range();
     Range(int _start, int _end);
     Range(const CvSlice& slice);
     int size() const;
     bool empty() const;
     static Range all();
     operator CvSlice() const;

     int start, end;
 };
