What the literature leaves open

  • Further research can be done to improve the performance of the model in complex scenes.

    Swst-Net: Semantic-aware wavelet-driven structure and texture interaction network for image inpainting · 2026 · DOI

  • Existing virtual try-on approaches have large memory requirements. Existing approaches fail to preserve subtle garment details. There is a need for a more efficient and controllable virtual try-on framework.

    Controllable flow fields for high-fidelity virtual try-on with diffusion models · 2026 · DOI

  • Current feature learning methods lack interpretability. Deep learning models require large amounts of data and are not transparent. There is a need for methods that can learn from small datasets and provide interpretable results.

    Feature Learning by Induction · 2026 · DOI

  • One challenge is achieving accurate localization of editing regions. Another challenge is establishing cross-modal feature alignment between text and image modalities. The paper also identifies the need to balance semantic consistency and boundary precision in localized image editing as a challenge.

  • The training of such models requires tens of thousands of GPU hours of computing resources (with a single training cost exceeding $3 million), and is limited by the difficulty of building and maintaining a distributed training cluster at the kilocard level.

    Research On Text Generated Images Based on GAN And Diffusion · 2026 · DOI

  • Prior work has limitations, such as reliance on a priori linguistic templates, generation of generic information, and failure to accommodate linguistic diversity.

    Research on digital animation content generation technology for local cultural heritage using a multimodal data fusion method · 2026 · DOI

  • The lack of control over facial attributes and structural consistency in conventional GAN models. The need for a unified framework that integrates controlled face variation and artistic stylization. The limited flexibility and efficiency of conventional standalone approaches.

    Generation of Fake Human Faces Using GAN’S · 2026 · DOI

  • Model optimization techniques such as pruning, quantization, and knowledge distillation for lightweight GAN-based synthetic face generation have not been implemented or benchmarked.
