•Can solve using Newton’s method
–Also known as Newton-Raphson method
–Today’s reading (first four pages)

•Lukas-Kanade method does one iteration of Newton’s method
–Better results are obtained via more iterations
–
Improving accuracy
Recall our small motion assumption
This is not exact
•To do better, we need to add higher order terms back in:
This is a polynomial root finding problem
1D case
