Save and Load cv::Mat as a binary file.

It requires OpenCV 2.0 or later.

cv::FileStorage is not so fast to save cv::Mat of large size, because it writes datas as ASCII. So I write a code to save cv::Mat data as binary.

Just copy the whole functions in BinaryCvMat.cpp to your code or write header.

Mainly there are 2 functions

SaveMatBinary() //! Save cv::Mat as binary /*! \param[in] filename filaname to save \param[in] output cvmat to save */ bool SaveMatBinary(const std::string& filename, const cv::Mat& output);

//! Load cv::Mat as binary /*! \param[in] filename filaname to load \param[out] output loaded cv::Mat */ bool LoadMatBinary(const std::string& filename, cv::Mat& output);
