Before revision:  We conduct computational experiments that compare our stable methods to various state-of-the-art approaches using a set of well-established quality metrics that capture the two main criteria. These experiments demonstrate that our stable algorithms outperform existing methods on stability, without sacrificing spatial quality or efficiency.
After revision:  We conduct computational experiments that compare our stable methods to various state-of-the-art approaches using a set of well-established quality metrics that capture spatial quality and stability. We conclude that our stable algorithms outperform existing methods on stability, without sacrificing spatial quality or efficiency.
