Enhance and Upscale Images with Face Correction

Description:
This action utilizes the latest version of Real-ESRGAN to enhance images with adjustable upscale factors and optional face correction using GFPGAN. It is ideal for improving image resolution up to 1440p.

Category: image-enhancement

Input

The following fields are required and optional for this action:

• image (required): A valid URI of the input image that needs to be processed.
  • Example: https://replicate.delivery/pbxt/Ing7Fa4YMk6YtcoG1YZnaK3UwbgDB5guRc5M2dEjV6ODNLMl/cat.jpg
• scale (optional): The factor by which the image will be scaled. Must be between 0 and 10. The default value is 4.
  • Example: 2
• faceEnhance (optional): Indicates whether GFPGAN face enhancement should be applied in addition to upscaling. Defaults to false.
  • Example: false

Example Input:

{
  "image": "https://replicate.delivery/pbxt/Ing7Fa4YMk6YtcoG1YZnaK3UwbgDB5guRc5M2dEjV6ODNLMl/cat.jpg",
  "scale": 2,
  "faceEnhance": false
}

Conceptual Usage Example (Python)

Here’s a conceptual example of how to call the Enhance and Upscale Images with Face Correction action using Python:

import requests
import json

# Replace with your Cognitive Actions API key and endpoint
COGNITIVE_ACTIONS_API_KEY = "YOUR_COGNITIVE_ACTIONS_API_KEY"
COGNITIVE_ACTIONS_EXECUTE_URL = "https://api.cognitiveactions.com/actions/execute"  # Hypothetical endpoint

action_id = "3435d08f-06ab-46b4-b28e-3f576032bb9c"  # Action ID for Enhance and Upscale Images with Face Correction

# Construct the input payload based on the action's requirements
payload = {
    "image": "https://replicate.delivery/pbxt/Ing7Fa4YMk6YtcoG1YZnaK3UwbgDB5guRc5M2dEjV6ODNLMl/cat.jpg",
    "scale": 2,
    "faceEnhance": false
}

headers = {
    "Authorization": f"Bearer {COGNITIVE_ACTIONS_API_KEY}",
    "Content-Type": "application/json"
}

try:
    response = requests.post(
        COGNITIVE_ACTIONS_EXECUTE_URL,
        headers=headers,
        json={"action_id": action_id, "inputs": payload}  # Hypothetical structure
    )
    response.raise_for_status()  # Raise an exception for bad status codes (4xx or 5xx)

    result = response.json()
    print("Action executed successfully:")
    print(json.dumps(result, indent=2))

except requests.exceptions.RequestException as e:
    print(f"Error executing action {action_id}: {e}")
    if e.response is not None:
        print(f"Response status: {e.response.status_code}")
        try:
            print(f"Response body: {e.response.json()}")
        except json.JSONDecodeError:
            print(f"Response body: {e.response.text}")

In this example, replace YOUR_COGNITIVE_ACTIONS_API_KEY with your actual API key. The payload is constructed based on the input schema, ensuring that you correctly specify the image URL, scale, and whether to enhance faces.

Conclusion

The NightmareAI Real-ESRGAN Cognitive Actions provide an innovative way to enhance and upscale images, making it an invaluable tool for developers looking to improve image quality in their applications. With the ability to adjust scaling factors and apply face correction, these actions open up a range of possibilities for image processing. Consider integrating these capabilities into your projects to deliver striking visuals that captivate your users!
