Random sampling for fast face sketch synthesis.
Pattern Recognition(2018)
摘要
•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.
