Description

I use visual studio 2010 and opencv 2.4.4. It's strange to get a compile error when I try to get an iterator for SparseMat. The error message and sample code are:

opencv2\core\mat.hpp(2284): error C2440: '<function-style-cast>' : cannot convert from 'cv::SparseMat *const ' to 'cv::SparseMatIterator_<_Tp>'

int main(int argc, char* argv[]){
    int sz[2] = {10, 10};
    SparseMat sparse_mat(2, sz, CV_32FC1);
    SparseMatIterator_<float> it = sparse_mat.begin<float>(); 
    return 0;
}

Hello, Ming-Ming Cheng.

Try to use SparseMat_<float>:

SparseMat_<float> sparse_mat(2, sz);
SparseMatIterator_<float> it = sparse_mat.begin();
