FAQs

What are the primary applications of HAT?

HAT is primarily used for image super-resolution, which involves increasing the resolution of an image, and image restoration, focusing on improving the quality of degraded images. It's suitable for both academic research and practical applications requiring high-fidelity visual enhancements.

Does HAT support real-world image super-resolution?

Yes, HAT includes GAN-based models specifically designed for real-world super-resolution. These models, such as Real_HAT_GAN_SRx4 and Real_HAT_GAN_SRx4_sharper, offer options for better fidelity or sharper perceptual quality depending on the user's needs.

Can HAT be used with limited GPU memory?

Yes, HAT provides a tile mode for inference, which is particularly useful when working with limited GPU memory. This feature allows users to process images in smaller sections, making the tool accessible even with less powerful hardware.
