Whether you are looking to upscale images for a website, an app, or print media, this service streamlines the process and enhances the visual appeal of your content.

Prerequisites

To get started with the Rivers Stable Diffusion Upscaler, you will need a Cognitive Actions API key and a basic understanding of how to make API calls.

Implement Stable Diffusion Upscaler

The "Implement Stable Diffusion Upscaler" action allows you to execute the RiversHaveWings Stable Diffusion Upscaler to enhance images using guided text prompts and advanced sampling techniques. This operation is designed to solve the problem of low-resolution images by providing various customizable parameters such as seed value, inference steps, and noise augmentation, ensuring high-quality image upscaling.

Input Requirements

To utilize this action, you will need to provide the following inputs:

  • Image: A URI of the input image to be processed.
  • Seed: An integer for randomization (default: 0).
  • Steps: The number of inference steps to perform (default: 50, range: 0-100).
  • Prompt: A text prompt that guides the image processing.
  • Sampler: The algorithm to use for sampling (options include k_euler, k_euler_ancestral, k_dpm_2_ancestral, k_dpm_fast, k_dpm_adaptive).
  • Guidance Scale: A scale factor for guidance during processing (default: 1, range: 0-10).
  • Tolerance Scale: Used to set an error tolerance level for adaptive solving (default: 0.25).
  • Estimated Time Noise: Degree of noise added per step (default: 1, range: 0-10).
  • Noise Augmentation Type: Type of noise augmentation to apply (options: gaussian, fake).
  • Noise Augmentation Level: Level of noise augmentation (default: 0, range: 0-1).

Expected Output

The expected output is a URI link to the enhanced image, which will display the upscaled version based on the parameters provided.

Use Cases for this Action

This action is particularly useful in scenarios where image quality is paramount. For instance:

  • E-commerce: Enhance product images to attract more customers by providing detailed views.
  • Marketing: Improve visuals for advertisements, ensuring high resolution that captures attention.
  • Content Creation: Upscale images for blogs, social media posts, and websites to maintain professionalism.
  • Art Restoration: Revive and upscale historical images for archival and display purposes.
