    Basic Structures: main data structures used in opencv.


    CvPoint 
    CvPoint2D32f 
    CvPoint2D64f 
    CvPoint3D32f 
    CvPoint3D64f 

    Point_<typename _Tp> 
    Point3_<typename _Tp> 
    Point_<int>(Point2i, Point) 
    Point_<float>(Point2f) 
    Point_<double>(Point2d) 
    Point3_<float>(Point3f) 
    Point3_<double>(Point3d) 
    Point3_<int>(Point3i)


    System.Drawing.Point 
    System.Drawing.PointF 
    MCvPoint2D64f 
    MCvPoint3D32f 
    MCvPoint3D64f 


    CvSize 
    CvSize2D32f 
    Size_<typename _Tp> 
    Size_<int>(Size, Size2i) 
    Size_<float>(Size2f) 

    System.Drawing.Size 
    System.Drawing.SizeF 

    CvRect 
    Rect_<typename _Tp> 
    Rect_<int>(Rect) 

    System.Drawing.Rectangle 
    CvScalar 
    (A container for 1-,2-,3-or4-tuples of doubles)
    Scalar_<typename _Tp> 
    Scalar_<double>(Scalar) 
    (:public Vec<_Tp, 4>) 
    (Scalar is widely used to pass pixel values)

    MCvScalar 


    CvBox2D RotatedRect MCvBox2D
    CvMat 
    (A multi-channel dense matrix) – obsolete
    Mat MCvMat 
    MCvHistogram 
    Matrix<TDepath>(wrapper)
    CvMatND 
    (Multi-dimensional dense multi-channel array) – obsolete
    MCvMatND 
    MatND<TDepth>(wrapper)
    IplImage MIplImage 
    Image<TColor, TDepth>(wrapper)
    CvSparseMat SparseMat SparseMatrix<TDepath>(wrapper)
    CvArr 
    (“metatype”only used as function parameter)
    InputArray 
    OutputArray
    CvArray<TDepth>(wrapper)
    CvTermCriteria 
    (Termination criteria for iterative algorithms)
    TermCriteria MCvTermCriteria
    Dynamic Structures: for creating growable sequences and other dynamic data structures allocated in CvMemStorage. If you use the new C++, Python, Java etc interface, you will unlikely need this functionality. Use std::vector or other high-level data structures instead.
    CvMemStorage MemStorage MemStorage(wrapper)
    CvMemBlock    
    CvMemStoragePos    
    CvSeq Seq<typename _Tp> MCvSeq 
    Seq<T>(wrapper)
    CvSlice Range MCvSlice
    CvSet 
    (derived from CvSeq)
      MCvSet
    CvGraph 
    (derived from CvSet)
       
    CvGraphScanner 
    (used for depth-first graph traversal)
       
    CvTreeNodeIterator 
    (used to traverse trees of sequences)
       
    Extra C++ Basic Structures: some basic structures in C++ version.
    Matx<typename _Tp, int m, int n> 
    typedef Matx<float, 1, 2> Matx12f; 
    typedef Matx<double, 6, 6> Matx66d; 
    ...
    Vec<typename _Tp, int n> (:public Matx<_Tp, n, 1>) 
    typedef Vec<uchar, 2> Vec2b; 
    typedef Vec<short, 4> Vec4s; 
    typedef Vec<int, 3> Vec3i; 
    ...float,double...
    Ptr<typename _Tp> 
    for smart reference-counting pointers
    MatExpr 

    Matrix Expressions: (Mat A, B; Scalar s; double alpha) 
    • Addition, substraction, negation: A + B, A - B, A + s, A - s, s - A, -A
    • Scaling: A * alpha
    • Per-element multiplication and division: A.mul(B), A/B, alpha/A
    • Matrix multiplication: A*B
    • Transposition: A.t() (means AT)
    • Matrix inversion and pseudo-inversion, solving linear systems and least-squares problems: A.inv([method]) (~ A-1) , A.inv([method])*B (~ X: AX=B)
    • Comparison: A cmpop B, A cmpop alpha, alpha cmpop A, where cmpop is one of : >, >=, ==, !=, <=, <. The result of comparison is an 8-bit single channel mask whose elements are set to 255 (if the particular element or pair of elements satisfy the condition) or 0.
    • Bitwise logical operations: A logicop B, A logicop s, s logicop A, ~A, where logicop is one of : &, |, ^.
    • Element-wise minimum and maximum: min(A, B), min(A, alpha), max(A, B), max(A, alpha)
    • Element-wise absolute value: abs(A)
    • Cross-product, dot-product: A.cross(B) A.dot(B)
    • Any function of matrix or matrices and scalars that returns a matrix or a scalar, such as norm, mean, sum, countNonZero, trace, determinant, repeat, and others.
    • Matrix initializers ( Mat::eye(), Mat::zeros(), Mat::ones() ), matrix comma-separated initializers, matrix constructors and operators that extract sub-matrices (see Mat description).
    • Mat_<destination_type>() constructors to cast the result to the proper type.
