// This makes the algorithm more robust against a bit inhomogeneous parts in the zone

// The drawback is if we want to delimitate a zone wich color is very similar to the zone
// we consider as the OUTSIDE, the result will be bad.
// The current use cases are more of the first form :
// - Strongly contrasted INSIDE and OUTSIDE zones
