Generative adversarial classifier for handwriting characters super-resolution

Highlights：

• cylinder primitive extraction is addressed as a clustering problem of possible cylinder candidates;

• candidates are generated by cutting the scene through several random planes;

• a novel cylinder similarity function based on dual quaternion algebra is defined;

• the clustering process, based on Game Theory, inherently discards incompatible candidates;

• the proposed method can deal with noisy, partially occluded and non-oriented point clouds.
