SparseMat - better design

I would very much like to redesign the sparse matrix support in OpenCV. Is anybody else interested, knowledgeable on this issue?

More exactly, I need to support operations such as matrix multiplication, add, etc and they don't look to be supported. Therefore, I believe a better format for efficiency for sparse matrix representation should be CSR/CSC, not DOK (Dictionary of Keys), as it is right now. Also, I need to use in OpenCV operations on sparse matrices such as warpPerspective, etc which boil down to remap .

Thank you,

Basically @hilton bristow was pushing to adapt the sparse matrix interface in this feature request. I suggest getting in touch with him!
