The curvedness is a positive number that specifies the amount of curvature, whereas the shape index is a number in the range [−1, +1] and is scale invariant. The shape index captures the intuitive notion of 'local shape' particularly well. The shape index can be mapped upon an intuitively natural colour scale.
