1. Again, loosely speaking, second order derivatives are related to curvature.
2. Second order derivative filter sets have been investigated for transparent motion estimation.
3. For elliptic PDEs involving second order derivatives, we need " two " global relations.
4. In central differencing scheme and second order upwind scheme the first order derivative is included and the second order derivative is ignored.
5. The key idea here is that we consider a particular linear combination of zeroth, first and second order derivatives " all at once ".
6. It's difficult to find second order derivative in a sentence. 用second order derivative造句挺難的
7. He showed how first and second order derivatives can be computed correctly using cubic or trigonometric splines by a double filtering approach giving filters of length 7.
8. These schemes are therefore considered second order accurate where as QUICK does take the second order derivative into account, but ignores the third order derivative hence this is considered third order accurate.
