DXDYFilter Class Reference

DXDYFilter is a more advanced version of SimpleFilter. It allows combining derivatives of the inputs and also, unlike SimpleFilter, it defines derivatives of the filtered result. The user-supplied combining function has a different format: it takes and must return also the DX and DY values. More...

Detailed Description

DXDYFilter is a more advanced version of SimpleFilter. It allows combining derivatives of the inputs and also, unlike SimpleFilter, it defines derivatives of the filtered result. The user-supplied combining function has a different format: it takes and must return also the DX and DY values.
