Model overview

The esrgan model is an image super-resolution model that can upscale low-resolution images by 4x. It was developed by researchers at Tencent and the Chinese Academy of Sciences, and is an enhancement of the SRGAN model. The esrgan model uses a deeper neural network architecture called Residual-in-Residual Dense Blocks (RRDB) without batch normalization layers, which helps it achieve superior performance compared to previous models like SRGAN. It also employs the Relativistic average GAN loss function and improved perceptual loss to further boost image quality.

The esrgan model can be seen as a more advanced version of the Real-ESRGAN model, which is a practical algorithm for real-world image restoration that can also remove JPEG compression artifacts. The Real-ESRGAN model extends the original esrgan with additional features and improvements.

Model inputs and outputs

Inputs

  • Image: A low-resolution input image that the model will upscale by 4x.

Outputs

  • Image: The output of the model is a high-resolution image that is 4 times the size of the input.

Capabilities

The esrgan model can effectively upscale low-resolution images while preserving important details and textures. It outperforms previous state-of-the-art super-resolution models on standard benchmarks like Set5, Set14, and BSD100 in terms of both PSNR and perceptual quality. The model is particularly adept at handling complex textures and details that can be challenging for other super-resolution approaches.

What can I use it for?

The esrgan model can be useful for a variety of applications that require high-quality image upscaling, such as enhancing old photos, improving the resolution of security camera footage, or generating high-res images from low-res inputs for graphic design and media production. Companies could potentially use the esrgan model to improve the visual quality of their products or services, such as by upscaling product images on an ecommerce site or enhancing the resolution of user-generated content.

Things to try

One interesting aspect of the esrgan model is its network interpolation capability, which allows you to smoothly transition between the high-PSNR and high-perceptual quality versions of the model. By adjusting the interpolation parameter, you can find the right balance between visual fidelity and objective image quality metrics to suit your specific needs. This can be a powerful tool for fine-tuning the model's performance for different use cases.

Setting this to a non-zero value can help with GPU memory issues, but may introduce some artifacts. scale**: The desired upscaling factor, typically 2x or 4x. version**: The version of the realesrgan model to use, such as the general "General - v3" or the anime-optimized "RealESRGAN_x4plus_anime_6B". face_enhance**: A boolean flag to enable face enhancement using the GFPGAN model. This is not recommended for anime/cartoon-style images. Outputs The upscaled and restored output image, returned as a URI. Capabilities realesrgan can effectively restore and upscale a variety of image types, from natural scenes to anime/cartoon-style images. It can handle noise, blur, and other common degradations, producing high-quality results. The model's versatility comes from its synthetic training data, which covers a wide range of image characteristics. What can I use it for? realesrgan is a powerful tool for enhancing the resolution and quality of images, with applications in photography, graphic design, animation, and more. It can be used to upscale and restore low-quality images, such as those from the web or old photos, to create high-quality assets for various projects. For example, you could use realesrgan to upscale and restore images for use in website backgrounds, social media posts, or marketing materials. It could also be used to enhance the quality of anime or cartoon images for use in fan art, illustrations, or game assets. Things to try One interesting aspect of realesrgan is its ability to handle both natural images and anime/cartoon-style images well. You could try experimenting with different input images, comparing the results of the general "General - v3" model to the anime-optimized "RealESRGAN_x4plus_anime_6B" model. This can help you understand the strengths and limitations of each version and choose the best one for your specific use case. Additionally, you could try adjusting the scale parameter to see how it affects the output quality and file size. Experimenting with the tile size can also be useful, as it can help mitigate GPU memory issues, but may introduce some artifacts.
