Generative Adversarial Networks (GANs) have transformed image super-resolution by learning real-world image distributions. The research article ‘SeD: Semantic-Aware Discriminator for Image Super-Resolution’ addresses the issue of coarse-grained learning in GANs that may lead to virtual textures. The proposed solution, SeD, allows GANs to learn fine-grained distributions by leveraging image semantics. This is achieved via a well-designed spatial cross-attention module incorporating features from pretrained vision models.

• Introduces SeD for fine-grained semantic-aware texture learning in SR tasks.
• Utilizes pretrained vision models for accurate and abundant semantic extraction.
• The enhanced SR network produces photorealistic and visually appealing images.
