This paper proposes an automatic FSS algorithm with local strategy based on embedded hidden Markov model (E-HMM) and selective ensemble (SE). By using E-HMM to model the nonlinear relationship between a photo-sketch patch pair, a series of pseudo-sketch patches, generated based on several learned models for a given photo patch, are integrated with SE strategy to synthesize a finer face pseudo-sketch patch. Finally, the intact pseudo-sketch can be generated by combining all synthesized patches. Experimental results illustrate that the proposed FSS algorithm works well. \itemrv{~} \itemcc{} \itemut{facial sketch synthesis; sketch-photo recognition; E-HMM; selective ensemble; pseudo-sketch} \itemli{doi:10.1016/j.neucom.2007.10.025} \end
