Whether you’re enhancing product images for an online store or restoring old photographs, the Real-ESRGAN A100 service delivers a streamlined solution to meet your image quality needs.

Prerequisites

To start using the Real-ESRGAN A100 service, you will need a Cognitive Actions API key and a foundational understanding of API calls to integrate this powerful image upscaling feature into your applications.

Upscale Image Using Real-ESRGAN on A100

The "Upscale Image Using Real-ESRGAN on A100" action is designed to enhance the resolution of images while preserving essential details, making it a vital tool in various creative and professional scenarios. This action solves the problem of low-resolution images, allowing users to upscale them to a higher quality that meets today's visual standards.

Input Requirements

The action requires a JSON object with the following properties:

  • image (string, required): The URI of the input image. It must be a valid URL.
  • scale (number, optional): The factor by which the image will be scaled, ranging from 0 to 10, with a default value of 4.
  • faceEnhance (boolean, optional): A flag to apply GFPGAN face enhancement alongside the upscaling, defaulting to false.

Example Input:

{
  "image": "https://replicate.delivery/pbxt/IS6z50uYJFdFeh1vCmXe9zasYbG16HqOOMETljyUJ1hmlUXU/keanu.jpeg",
  "scale": 4,
  "faceEnhance": true
}

Expected Output

The output is a URI of the upscaled image, providing a higher resolution version of the original input.
