    4KLSDB: A Large-Scale Dataset for 4K Image Restoration and Generation

    Researchers have introduced the 4K Large Scale Dataset and Benchmark (4KLSDB), a new collection of nearly 130,000 high-resolution images. This dataset is designed to address the limitations of existing resources for training advanced super-resolution and text-to-image models. The 4KLSDB includes diverse categories and has undergone extensive filtering and annotation, demonstrating its effectiveness in improving model performance on native 4K benchmarks. AI

    IMPACT Provides a crucial resource for training higher-fidelity image synthesis and restoration models at native 4K resolution.
