Hi Knead.

Find the answer here:

White points mark the maximum curvature points in a portion on the curve where the curvature starts to decrease in both directions from the points.

Black points mark the minimum curvature points where the curvature circle jumps from one side of the curve to the other side. The curvature at the black points is always 0.
