Probability distributions for the master view of a guitar (left figures) and its view after 45° rotation (right) (Fig. 7). It can be seen that D2 (d right), after 45° rotation) is very hazy and noisy and far from being similar to its unchanged pose view’s PDF (d left). But KPD and GKPD shape is still consistent (left, right of ac). KPDs maintain better consistency than GKPDs when it comes to retaining geometric structure. a Left KPD of master guitar view. Right KPD of the same guitar after rotation. b Left GKPD of master guitar view. Right GKPD of the same guitar after rotation. c Left Weighted GKPD of master guitar view. Right Weighted GKPD of the same guitar after rotation. d Left Shape distribution D2 of master guitar view. Right Shape distribution D2 of the same guitar after rotation
