The structure of A Facial Structure Sampling Contrastive Learning Method for Sketch Facial Synthesis (FSS). Here, G is the generator, E is the encoder module of the G, D is the discriminator, H is the block feature extractor, and Region-Constrained Sampling (RCS) is responsible for selecting samples with specific positional constraints as samples required for computing block contrastive loss. During the sample selection process, we introduce the Dynamic Sampling Strategy (DSS) to address the imbalance between positive and negative samples.
