Enhance Image Resolution Effortlessly with ControlNet Tile

In the world of digital imagery, the need for high-resolution images is ever-increasing, whether for professional photography, graphic design, or content creation. The "Controlnet Tile" service provides developers with powerful Cognitive Actions that enable seamless image enhancement. One of the standout features is the ability to upscale images using ControlNet v1.1 Tile Version, allowing you to enhance SDXL images from 1024 up to 2048 pixels. This process not only improves image clarity and detail but does so efficiently, making it an ideal solution for developers looking to integrate image enhancement capabilities into their applications.

Use Cases:

  • E-commerce Platforms: Enhance product images to attract customers with better visual quality.
  • Social Media Applications: Improve user-uploaded images for a more professional look.
  • Graphic Design Tools: Provide designers with the ability to upscale images without losing detail, making their workflow smoother.
  • Content Creation: Enable creators to produce high-quality visuals for blogs, videos, or presentations.

Enhance Image Resolution with ControlNet

The "Enhance Image Resolution with ControlNet" action is designed to upscale images while preserving or improving their quality. This action leverages a diffusion-based text-to-image generation model conditioned on tiled images, solving the problem of low-resolution images that lack detail.

Input Requirements:

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

  • Image (URI): A required field that specifies the URI of the input image you want to enhance. For example, https://replicate.delivery/pbxt/JwoDHQ0gIgBPeiXQPiAI0s7NVFkRxDLwXie51LIhDBYWIvBe/ship.jpg.
  • Scale Multiplier (integer): Specifies the factor by which to multiply the image resolution. Options include 2, 4, 8, and 16, with a default of 2.
  • Strength (number): Determines the strength of the diffusion process. This value ranges from 0.1 to 2, with a default of 0.5.
  • Number of Inference Steps (integer): Defines the number of steps in the inference process, ranging from 1 to 100, with a default of 32.
  • Seed (integer): A random seed used for generating deterministic variations. This is optional and can be left blank for a random value.

Expected Output:

The output of this action is a high-resolution version of the input image. For example, an enhanced image might return a URI like https://assets.cognitiveactions.com/invocations/918d298d-0918-49c5-a1f4-1f4b2320457f/5dae2188-a445-4124-8e77-de6bd558bc1f.png.

Use Cases for this Specific Action:

  • Photography Enhancement: Photographers can upscale their images for high-quality prints or online portfolios, ensuring every detail is captured.
  • Art Restoration: Digital restorers can use this action to enhance scanned images of artwork, bringing new life to historical pieces.
  • Real Estate Listings: Agents can improve property images to showcase homes in the best light, attracting potential buyers.

```python
import requests
import json

# Replace with your actual Cognitive Actions API key and endpoint
# Ensure your environment securely handles the API key
COGNITIVE_ACTIONS_API_KEY = "YOUR_COGNITIVE_ACTIONS_API_KEY"
# This endpoint URL is hypothetical and should be documented for users
COGNITIVE_ACTIONS_EXECUTE_URL = "https://api.cognitiveactions.com/actions/execute"

action_id = "58993a90-c9f9-41c2-9f2d-8102e3abb8c6" # Action ID for: Enhance Image Resolution with ControlNet

# Construct the exact input payload based on the action's requirements
# This example uses the predefined example_input for this action:
payload = {

  "scale": 2,
  "strength": 0.15,
  "numberOfInferenceSteps": 32
}

headers = {
    "Authorization": f"Bearer {COGNITIVE_ACTIONS_API_KEY}",
    "Content-Type": "application/json",
    # Add any other required headers for the Cognitive Actions API
}

# Prepare the request body for the hypothetical execution endpoint
request_body = {
    "action_id": action_id,
    "inputs": payload
}

print(f"--- Calling Cognitive Action: {action.name or action_id} ---")
print(f"Endpoint: {COGNITIVE_ACTIONS_EXECUTE_URL}")
print(f"Action ID: {action_id}")
print("Payload being sent:")
print(json.dumps(request_body, indent=2))
print("------------------------------------------------")

try:
    response = requests.post(
        COGNITIVE_ACTIONS_EXECUTE_URL,
        headers=headers,
        json=request_body
    )
    response.raise_for_status() # Raise an exception for bad status codes (4xx or 5xx)

    result = response.json()
    print("Action executed successfully. Result:")
    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 (non-JSON): {e.response.text}")
    print("------------------------------------------------")
