Comparison of PR-GLS and its fast version (PR-GLS-F) with SC [23], TPS-RPM [3], RPM-LNS [13], GMMREG [19], CPD [11] and RPM-L2E [28] on the fish (top) and Chinese character (bottom) [3], [13]. The error bars indicate the registration error means and standard deviations over 100 trials. Note that the variance bar can reach the negative y-axis, where large variance indicates that a method sometimes works well and sometimes totally fails.
