Registration examples on the Chinese character point set.

From top to bottom are the four largest degradations: deformation (0.08), noise (0.05), occlusion (0.5), and outlier (2.0). The model point set is shown in blue pluses, and the scene point set is shown in red circles.从顶部至底部依次展示四种最为显著的退化类型：形变（0.08）、噪声（0.05）、遮挡（0.5）与异常值（2.0）。模型点集以蓝色加号标注，场景点集以红色圆圈标注。
