Random sampling for fast face sketch synthesis

作者:

Highlights:

• We proposed a simple but effective offline random sampling in place of online K-NN search to improve the efficiency of face sketch synthesis.

• The proposed method could be extended to other heterogeneous face image transformation problems such as face hallucination

• We release the source codes of our proposed methods and the evaluation metrics for future study online: http://www.ihitworld.com/RSLCR.html.
