Quantifying Matching Localization<br />
For a particular image patch, we want to<br />
find out how accurately it can be localized<br />
1. Consider image patch at the solution point<br />
(i.e. perfect matching location where SSD=0)<br />
2. Estimate how much SSD increases when<br />
image patch is displaced by small amounts in<br />
different directions<br />
We can use partial derivatives to estimate<br />
the increase in SSD<br />
