Detailed Description
Read-Only Sparse Matrix Iterator.
Here is how to use the iterator to compute the sum of floating-point sparse matrix elements:
SparseMatConstIterator it = m.begin(), it_end = m.end(); double s = 0; CV_Assert( m.type() == CV_32F ); for( ; it != it_end; ++it ) s += it.value<float>();
