[Question] When source landmarks not one-on-one match to Target landmarks

[JUN WANG]

Hi, I have two questions:

1. When the target landmarks are less than source landmarks, i.e. say source landmarks = [1, 2,3,4,5,6,7,8,9,10], but target landmarks only contains [2,4,7,9], what should we do to achieve the correspondence?
2. When some source landmarks correspond to the same points on target model, i.e. ls_source[2], ls_source[3] both correspond to ls_target[2], what should we do to achieve the correspondence?
