In general terms, the Hausdorff Distance is the maximum distance of a set to the nearest point in the other set. As we have two sets (two meshes) the Hausdorff distance is the maximum of the two distances (A to B and B to A). These two distances are not symmetric (quite often we say that the Hausdorff distance is oriented) so both of them need to be calculated.
```math
H(A,B) = max\{h (A, B), h (B, A)\} \\[2mm]
with: \\[2mm]
h (A, B) = \max_{a \in A} \{ \min_{b \in B} \{ d(a,b)\} \} \\[2mm]
```
Meshlab provides a Hausdorff distance calculation (a filter) so we decided to use it to calculate our quality parameter. For simplicity we used the python library Pymeshlab to automatize the quality calculation.
