Detailed Description

template<typename _Tp>
class cv::SparseMat_< _Tp >

The Template Sparse Matrix class derived from cv::SparseMat

The class provides slightly more convenient operations for accessing elements.

SparseMat m;
...
SparseMat_<int> m_ = (SparseMat_<int>&)m;
m_.ref(1)++; // equivalent to m.ref<int>(1)++;
m_.ref(2) += m_(3); // equivalent to m.ref<int>(2) += m.value<int>(3);
