Seonglae ChoLimitation
- The motion is larger than a pixel
- find large motion from coarse image
- A point does not move like its neighbor
- Brightness constancy does not hold
We can figure out whether the system is solvable by looking at the eigenvalues of the
second moment matrix
Limitation
- motion is larger than pixel
- broken
- motion segmentation
- could not hold
- Exhaustive neighborhood search with normalized correlation
