INTRODUCTION
The level set is defined as the set of points that have the same function value.
The sole purpose of the level set function is to provide an implicit representation of the evolving curve.
Instead of tracking a curve through time, the level set method evolves a curve by updating the level set function at fixed coordinates through time.
