| How to get more
equations for a pixel? |
||||||||||||
| • | Basic idea: impose additional constraints |
|||||||||||
| – | most common is to
assume that the flow field is smooth locally |
|||||||||||
| – | one method: pretend the pixel’s neighbors have the
same (u,v) |
|||||||||||
| » | If we use a 5x5
window, that gives us 25 equations per pixel! |
