What is the evidence that a shape based approach could perform better

[gerddie]

Q38:

If the author want to say ‘the method would work better given with reasonable landmarks (shape features), it would better to provide an evidence. The evidence may be acquired by analyzing subset of data that succeeded in landmark (shape feature) identification.

A more thorough exploration of the conditions of failure are needed to disprove that a shape based method based on landmarks will not work.
