// The n-dimensional matrix class.
//
// The class represents an n-dimensional dense numerical array that can act as
// a matrix, image, optical flow map, 3-focal tensor etc.
// It is very similar to CvMat and CvMatND types from earlier versions of OpenCV,
// and similarly to those types, the matrix can be multi-channel. It also fully supports ROI mechanism.
//
// There are many different ways to create cv::Mat object. Here are the some popular ones:
// <ul>
// <li> using cv::Mat::create(nrows, ncols, type) method or
// the similar constructor cv::Mat::Mat(nrows, ncols, type[, fill_value]) constructor.
// A new matrix of the specified size and specifed type will be allocated.
// "type" has the same meaning as in cvCreateMat function,
// e.g. CV_8UC1 means 8-bit single-channel matrix, CV_32FC2 means 2-channel (i.e. complex)
// floating-point matrix etc:
//
// \code
// // make 7x7 complex matrix filled with 1+3j.
// cv::Mat M(7,7,CV_32FC2,Scalar(1,3));
// // and now turn M to 100x60 15-channel 8-bit matrix.
// // The old content will be deallocated
// M.create(100,60,CV_8UC(15));
// \endcode
//
// As noted in the introduction of this chapter, Mat::create()
// will only allocate a new matrix when the current matrix dimensionality
// or type are different from the specified.
//
// <li> by using a copy constructor or assignment operator, where on the right side it can
// be a matrix or expression, see below. Again, as noted in the introduction,
// matrix assignment is O(1) operation because it only copies the header
// and increases the reference counter. cv::Mat::clone() method can be used to get a full
// (a.k.a. deep) copy of the matrix when you need it.
//
// <li> by constructing a header for a part of another matrix. It can be a single row, single column,
// several rows, several columns, rectangular region in the matrix (called a minor in algebra) or
// a diagonal. Such operations are also O(1), because the new header will reference the same data.
// You can actually modify a part of the matrix using this feature, e.g.
//
// \code
// // add 5-th row, multiplied by 3 to the 3rd row
// M.row(3) = M.row(3) + M.row(5)*3;
//
// // now copy 7-th column to the 1-st column
// // M.col(1) = M.col(7); // this will not work
// Mat M1 = M.col(1);
// M.col(7).copyTo(M1);
//
// // create new 320x240 image
// cv::Mat img(Size(320,240),CV_8UC3);
// // select a roi
// cv::Mat roi(img, Rect(10,10,100,100));
// // fill the ROI with (0,255,0) (which is green in RGB space);
// // the original 320x240 image will be modified
// roi = Scalar(0,255,0);
// \endcode
//
// Thanks to the additional cv::Mat::datastart and cv::Mat::dataend members, it is possible to
// compute the relative sub-matrix position in the main "container" matrix using cv::Mat::locateROI():
//
// \code
// Mat A = Mat::eye(10, 10, CV_32S);
// // extracts A columns, 1 (inclusive) to 3 (exclusive).
// Mat B = A(Range::all(), Range(1, 3));
// // extracts B rows, 5 (inclusive) to 9 (exclusive).
// // that is, C ~ A(Range(5, 9), Range(1, 3))
// Mat C = B(Range(5, 9), Range::all());
// Size size; Point ofs;
// C.locateROI(size, ofs);
// // size will be (width=10,height=10) and the ofs will be (x=1, y=5)
// \endcode
//
// As in the case of whole matrices, if you need a deep copy, use cv::Mat::clone() method
// of the extracted sub-matrices.
//
// <li> by making a header for user-allocated-data. It can be useful for
// <ol>
// <li> processing "foreign" data using OpenCV (e.g. when you implement
// a DirectShow filter or a processing module for gstreamer etc.), e.g.
//
// \code
// void process_video_frame(const unsigned char* pixels,
// int width, int height, int step)
// {
// cv::Mat img(height, width, CV_8UC3, pixels, step);
// cv::GaussianBlur(img, img, cv::Size(7,7), 1.5, 1.5);
// }
// \endcode
//
// <li> for quick initialization of small matrices and/or super-fast element access
//
// \code
// double m[3][3] = {{a, b, c}, {d, e, f}, {g, h, i}};
// cv::Mat M = cv::Mat(3, 3, CV_64F, m).inv();
// \endcode
// </ol>
//
// partial yet very common cases of this "user-allocated data" case are conversions
// from CvMat and IplImage to cv::Mat. For this purpose there are special constructors
// taking pointers to CvMat or IplImage and the optional
// flag indicating whether to copy the data or not.
//
// Backward conversion from cv::Mat to CvMat or IplImage is provided via cast operators
// cv::Mat::operator CvMat() an cv::Mat::operator IplImage().
// The operators do not copy the data.
//
//
// \code
// IplImage* img = cvLoadImage("greatwave.jpg", 1);
// Mat mtx(img); // convert IplImage* -> cv::Mat
// CvMat oldmat = mtx; // convert cv::Mat -> CvMat
// CV_Assert(oldmat.cols == img->width && oldmat.rows == img->height &&
// oldmat.data.ptr == (uchar*)img->imageData && oldmat.step == img->widthStep);
// \endcode
//
// <li> by using MATLAB-style matrix initializers, cv::Mat::zeros(), cv::Mat::ones(), cv::Mat::eye(), e.g.:
//
// \code
// // create a double-precision identity martix and add it to M.
// M += Mat::eye(M.rows, M.cols, CV_64F);
// \endcode
//
// <li> by using comma-separated initializer:
//
// \code
// // create 3x3 double-precision identity matrix
// Mat M = (Mat_<double>(3,3) << 1, 0, 0, 0, 1, 0, 0, 0, 1);
// \endcode
//
// here we first call constructor of cv::Mat_ class (that we describe further) with the proper matrix,
// and then we just put "<<" operator followed by comma-separated values that can be constants,
// variables, expressions etc. Also, note the extra parentheses that are needed to avoid compiler errors.
//
// </ul>
//
// Once matrix is created, it will be automatically managed by using reference-counting mechanism
// (unless the matrix header is built on top of user-allocated data,
// in which case you should handle the data by yourself).
// The matrix data will be deallocated when no one points to it;
// if you want to release the data pointed by a matrix header before the matrix destructor is called,
// use cv::Mat::release().
//
// The next important thing to learn about the matrix class is element access. Here is how the matrix is stored.
// The elements are stored in row-major order (row by row). The cv::Mat::data member points to the first element of the first row,
// cv::Mat::rows contains the number of matrix rows and cv::Mat::cols - the number of matrix columns. There is yet another member,
// cv::Mat::step that is used to actually compute address of a matrix element. cv::Mat::step is needed because the matrix can be
// a part of another matrix or because there can some padding space in the end of each row for a proper alignment.
//
// \image html roi.png
//
// Given these parameters, address of the matrix element M_{ij} is computed as following:
//
// addr(M_{ij})=M.data + M.step*i + j*M.elemSize()
//
// if you know the matrix element type, e.g. it is float, then you can use cv::Mat::at() method:
//
// addr(M_{ij})=&M.at<float>(i,j)
//
// (where & is used to convert the reference returned by cv::Mat::at() to a pointer).
// if you need to process a whole row of matrix, the most efficient way is to get
// the pointer to the row first, and then just use plain C operator []:
//
// \code
// // compute sum of positive matrix elements
// // (assuming that M is double-precision matrix)
// double sum=0;
// for(int i = 0; i < M.rows; i++)
// {
// const double* Mi = M.ptr<double>(i);
// for(int j = 0; j < M.cols; j++)
// sum += std::max(Mi[j], 0.);
// }
// \endcode
//
// Some operations, like the above one, do not actually depend on the matrix shape,
// they just process elements of a matrix one by one (or elements from multiple matrices
// that are sitting in the same place, e.g. matrix addition). Such operations are called
// element-wise and it makes sense to check whether all the input/output matrices are continuous,
// i.e. have no gaps in the end of each row, and if yes, process them as a single long row:
//
// \code
// // compute sum of positive matrix elements, optimized variant
// double sum=0;
// int cols = M.cols, rows = M.rows;
// if(M.isContinuous())
// {
// cols *= rows;
// rows = 1;
// }
// for(int i = 0; i < rows; i++)
// {
// const double* Mi = M.ptr<double>(i);
// for(int j = 0; j < cols; j++)
// sum += std::max(Mi[j], 0.);
// }
// \endcode
// in the case of continuous matrix the outer loop body will be executed just once,
// so the overhead will be smaller, which will be especially noticeable in the case of small matrices.
//
// Finally, there are STL-style iterators that are smart enough to skip gaps between successive rows:
// \code
// // compute sum of positive matrix elements, iterator-based variant
// double sum=0;
// MatConstIterator_<double> it = M.begin<double>(), it_end = M.end<double>();
// for(; it != it_end; ++it)
// sum += std::max(*it, 0.);
// \endcode
//
// The matrix iterators are random-access iterators, so they can be passed
// to any STL algorithm, including std::sort().

// Template matrix class derived from Mat
//
// The class Mat_ is a "thin" template wrapper on top of cv::Mat. It does not have any extra data fields,
// nor it or cv::Mat have any virtual methods and thus references or pointers to these two classes
// can be safely converted one to another. But do it with care, for example:
//
// \code
// // create 100x100 8-bit matrix
// Mat M(100,100,CV_8U);
// // this will compile fine. no any data conversion will be done.
// Mat_<float>& M1 = (Mat_<float>&)M;
// // the program will likely crash at the statement below
// M1(99,99) = 1.f;
// \endcode
//
// While cv::Mat is sufficient in most cases, cv::Mat_ can be more convenient if you use a lot of element
// access operations and if you know matrix type at compile time.
// Note that cv::Mat::at<_Tp>(int y, int x) and cv::Mat_<_Tp>::operator ()(int y, int x) do absolutely the
// same thing and run at the same speed, but the latter is certainly shorter:
//
// \code
// Mat_<double> M(20,20);
// for(int i = 0; i < M.rows; i++)
// for(int j = 0; j < M.cols; j++)
// M(i,j) = 1./(i+j+1);
// Mat E, V;
// eigen(M,E,V);
// cout << E.at<double>(0,0)/E.at<double>(M.rows-1,0);
// \endcode
//
// It is easy to use Mat_ for multi-channel images/matrices - just pass cv::Vec as cv::Mat_ template parameter:
//
// \code
// // allocate 320x240 color image and fill it with green (in RGB space)
// Mat_<Vec3b> img(240, 320, Vec3b(0,255,0));
// // now draw a diagonal white line
// for(int i = 0; i < 100; i++)
// img(i,i)=Vec3b(255,255,255);
// // and now modify the 2nd (red) channel of each pixel
// for(int i = 0; i < img.rows; i++)
// for(int j = 0; j < img.cols; j++)
// img(i,j)[2] ^= (uchar)(i ^ j); // img(y,x)[c] accesses c-th channel of the pixel (x,y)

// {
// #if 1
// // intialize iterator (the style is different from STL).

// Mat planes[1];
// NAryMatIterator it(arrays, planes);
// double s = 0;
// // iterate through the matrix. on each iteration
// // it.planes[i] (of type Mat) will be set to the current plane of
// // i-th n-dim matrix passed to the iterator constructor.
// for(int p = 0; p < it.nplanes; p++, ++it)
// s += sum(it.planes[0])[0];
// it = NAryMatIterator(hist);
// s = 1./s;
// for(int p = 0; p < it.nplanes; p++, ++it)
// it.planes[0] *= s;
// #elif 1
// // this is a shorter implementation of the above
// // using built-in operations on Mat
// double s = sum(hist)[0];
// hist.convertTo(hist, hist.type(), 1./s, 0);
// #else
// // and this is even shorter one
// // (assuming that the histogram elements are non-negative)
// normalize(hist, hist, 1, 0, NORM_L1);
// #endif
// }
// \endcode
//
// You can iterate through several matrices simultaneously as long as they have the same geometry
// (dimensionality and all the dimension sizes are the same), which is useful for binary

// Sparse matrix class.
//
// The class represents multi-dimensional sparse numerical arrays. Such a sparse array can store elements
// of any type that cv::Mat is able to store. "Sparse" means that only non-zero elements
// are stored (though, as a result of some operations on a sparse matrix, some of its stored elements
// can actually become 0. It's user responsibility to detect such elements and delete them using cv::SparseMat::erase().
// The non-zero elements are stored in a hash table that grows when it's filled enough,
// so that the search time remains O(1) in average. Elements can be accessed using the following methods:
//
// <ol>
// <li>Query operations: cv::SparseMat::ptr() and the higher-level cv::SparseMat::ref(),
// cv::SparseMat::value() and cv::SparseMat::find, for example:
// \code
// const int dims = 5;
// int size[] = {10, 10, 10, 10, 10};
// SparseMat sparse_mat(dims, size, CV_32F);
// for(int i = 0; i < 1000; i++)
// {
// int idx[dims];
// for(int k = 0; k < dims; k++)
// idx[k] = rand()%sparse_mat.size(k);
// sparse_mat.ref<float>(idx) += 1.f;
// }
// \endcode
//
// <li>Sparse matrix iterators. Like cv::Mat iterators and unlike cv::Mat iterators, the sparse matrix iterators are STL-style,
// that is, the iteration is done as following:
// \code
// // prints elements of a sparse floating-point matrix and the sum of elements.
// SparseMatConstIterator_<float>
// it = sparse_mat.begin<float>(),
// it_end = sparse_mat.end<float>();
// double s = 0;
// int dims = sparse_mat.dims();
// for(; it != it_end; ++it)
// {
// // print element indices and the element value
// const Node* n = it.node();
// printf("(")
// for(int i = 0; i < dims; i++)
// printf("%3d%c", n->idx[i], i < dims-1 ? ',' : ')');
// printf(": %f\n", *it);
// s += *it;
// }
// printf("Element sum is %g\n", s);
// \endcode
// If you run this loop, you will notice that elements are enumerated
// in no any logical order (lexicographical etc.),
// they come in the same order as they stored in the hash table, i.e. semi-randomly.
//
// You may collect pointers to the nodes and sort them to get the proper ordering.
// Note, however, that pointers to the nodes may become invalid when you add more
// elements to the matrix; this is because of possible buffer reallocation.
//
// <li>A combination of the above 2 methods when you need to process 2 or more sparse
// matrices simultaneously, e.g. this is how you can compute unnormalized
// cross-correlation of the 2 floating-point sparse matrices:
// \code
// double crossCorr(const SparseMat& a, const SparseMat& b)
// {
// const SparseMat *_a = &a, *_b = &b;
// // if b contains less elements than a,
// // it's faster to iterate through b
// if(_a->nzcount() > _b->nzcount())
// std::swap(_a, _b);
// SparseMatConstIterator_<float> it = _a->begin<float>(),
// it_end = _a->end<float>();
// double ccorr = 0;
// for(; it != it_end; ++it)
// {
// // take the next element from the first matrix
// float avalue = *it;
// const Node* anode = it.node();
// // and try to find element with the same index in the second matrix.
// // since the hash value depends only on the element index,
// // we reuse hashvalue stored in the node
// float bvalue = _b->value<float>(anode->idx,&anode->hashval);
// ccorr += avalue*bvalue;
// }
// return ccorr;
// }
// \endcode

// XML/YAML File Storage Class.

// The class describes an object associated with XML or YAML file.
// It can be used to store data to such a file or read and decode the data.
//
// The storage is organized as a tree of nested sequences (or lists) and mappings.
// Sequence is a heterogenious array, which elements are accessed by indices or sequentially using an iterator.
// Mapping is analogue of std::map or C structure, which elements are accessed by names.
// The most top level structure is a mapping.
// Leaves of the file storage tree are integers, floating-point numbers and text strings.
//
// For example, the following code:
//
// \code
// // open file storage for writing. Type of the file is determined from the extension
// FileStorage fs("test.yml", FileStorage::WRITE);
// fs << "test_int" << 5 << "test_real" << 3.1 << "test_string" << "ABCDEFGH";
// fs << "test_mat" << Mat::eye(3,3,CV_32F);
//
// fs << "test_list" << "[" << 0.0000000000001 << 2 << CV_PI << -3435345 << "2-502 2-029 3egegeg" <<

//
// const uchar arr[] = {0, 1, 1, 0, 1, 1, 0, 1};
// fs.writeRaw("u", arr, (int)(sizeof(arr)/sizeof(arr[0])));
//
// fs << "]" << "}";
// \endcode
//
// will produce the following file:
//
// \verbatim
// %YAML:1.0
