Request for Code/Pseudocode for Mouth Opening Difference (MOD) Calculation

[Kedreamix]

Hi,

I'm struggling to understand how the Mouth Opening Difference (MOD) is calculated in the project. The existing docs aren't clear enough for me to replicate it.

Would it be possible to share the code snippet or pseudocode for the MOD calculation? Even a basic outline of the steps (like which landmarks are used, distance metrics, etc.) would help a lot.

Thanks!

"MOD measures the average difference in mouth opening region between predictions and ground truth."
Simply put, it averages the errors within the region where LVE is calculated, rather than taking the maximum value.

The lip region landmarks are from the official FLAME mask and contain 254 points.
