| - | The ClassClean logic computes a quality score for particles in context of a group of particles ("class"). Therefore, this logic requires particles to be aligned and classified beforehand - either by assignment to a reference from [[eyes:logics:Alignment]] or a class from [[eyes:logics:Classification]]classification. ClassClean can be operated in two modes: In "clean" mode particles are evaluated within each class and dependent on chosen parameters a certain fraction of only the best particles is kept. In "refine" mode existing classes from a previous "clean" mode run may be supplemented with a new set of particles. These new particles are then i) assigned to the best matching class, ii) evaluated within this class and iii) either kept when they improve the quality measure of this class or discarded. Using a circular mask helps in particle evaluation by removing background noise. Note: The ClassClean logic performs no alignment. | + | The ClassClean logic computes a quality score for particles in context of a group of particles ("class").
