description = "Gradio demo for <b>NAFNet: Nonlinear Activation Free Network for Image Restoration</b>. NAFNet achieves state-of-the-art performance on three tasks: image denoising, image debluring and stereo image super-resolution (SR). See the paper and project page for detailed results below. Here, we provide a demo for stereo image super-resolution (SR). To use it, simply upload your left and right view images, or click the examples to load them. Inference needs some time (>100s) since this demo uses CPU."
