Impact of dimensionality k on registration accuracy. (a) Illustrates the decrease in Euclidean distance error as k increases. (b) Shows the decrease in the transformation estimation error as k increases until reaching a value for which it is small and stable. It can be seen that for k 30 the transformation is identified accurately.
