cv type float

can u please explain the uses of each, like when we needed to use float type and when unsigned char. specifically if i nice, i just have to printf mat.type() of an unknown mat and refer back here. replydelete for those using cv::filestorage i created this (serialised) equivalent lookup table. c c c  a primitive opencv data type is one of unsigned char , bool , signed char , unsigned short , signed short , int , float , double , or a tuple of values of one of these . conversion to cv::vec operator vec() const; ! dot product _tp dot(const point_& pt) const; ! dot product computed in doubleprecision arithmetics  static public member functions. static int, type (). member function documentation. static int cv::flann::cvtype< float >::type, (, ). inlinestatic. the documentation for this struct was generated from the following file: flann/include/opencv/flann.hpp. generated on fri dec :: for opencv by doxygen .

mai brief a helper class for cv::datatype the class is specialized for each fundamental numerical data type supported by opencv. to support bit unsigned integers template class datadepth { public: enum { value = cv_s, fmt=(int)'i' }; }; template class datadepth<float> { public: enum  for mats nonfloatmat and floatmat when the first is the source matrix and the last is the destination matrix do nonfloatmat.convertto(floatmat, cv_f); if its a color image use cv_fc, or cv_fc if its rgba. convertto's reference can be found here. edit: and by the way, the code will work if you'll change the float  the emd function in opencv is cv::emd(): float cv::emd( cv::inputarray signature, szby(dims) float array cv::inputarray signature, szby(dims) float array int disttype, distance type (e.g., 'cv::dist_l') cv::inputarray cost cv::dist_user) float lowerbound bound on distance cv::outputarray flow
