AI Structure Control represents one of the most significant advances in AI image generation - the ability to guide generation using structural information from reference images. Using technologies like ControlNet, you can now create images that follow exact poses, maintain specific compositions, or preserve architectural layouts.
What is Structure Control?
Structure Control refers to techniques that allow you to guide AI image generation using structural information extracted from reference images. Instead of just describing what you want, you can show the AI the exact structure, pose, or composition you need.
The technology extracts:
- Edge contours and outlines
- Depth information and spatial relationships
- Human poses and body positions
- Architectural lines and perspectives
- Segmentation maps and regions
How Structure Control Works
Modern structure control uses conditioning mechanisms:
- Extraction: Structural information is extracted from your reference image
- Encoding: This structure is converted into a format the AI understands
- Conditioning: The generation process is guided by this structural information
- Generation: New content is created following the extracted structure
The result is an image that matches your creative vision while following the exact structural guidelines you provided.
Types of Structure Control
Canny Edge Detection
Uses edge outlines to guide generation:
- Preserves hard edges and contours
- Great for architectural subjects
- Maintains object boundaries
- Ideal for precise shape control
Best for: Architecture, product design, mechanical objects
Depth Maps
Uses 3D depth information:
- Preserves spatial relationships
- Maintains foreground/background separation
- Creates consistent 3D feel
- Excellent for landscapes and interiors
Best for: Landscapes, interior design, scene composition
Pose Estimation (OpenPose)
Detects human body positions:
- Captures exact poses and gestures
- Tracks multiple people
- Includes hand and face details
- Perfect for character work
Best for: Fashion, character design, action scenes
Normal Maps
Captures surface orientation:
- Preserves surface details
- Maintains 3D surface information
- Great for texture-heavy subjects
Best for: Product photography, detailed surfaces
Segmentation
Divides image into semantic regions:
- Defines areas by meaning (sky, ground, building)
- Allows region-specific generation
- Precise compositional control
Best for: Complex scenes, layout preservation
Line Art
Extracts clean linework:
- Follows artistic line drawings
- Great for illustration styles
- Preserves artistic intent
Best for: Illustration, concept art, anime style
Practical Applications
Product Visualization
- Maintain exact product shapes while changing materials
- Generate lifestyle photos keeping product position
- Create consistent product series with varying backgrounds
- Produce catalog images with uniform composition
Fashion and Character Design
- Generate clothing designs on consistent poses
- Create character variations maintaining body position
- Produce fashion lookbooks with uniform stances
- Design costumes using specific reference poses
Architecture and Interior Design
- Reimagine spaces while keeping layout
- Generate seasonal variations of buildings
- Create mood alternatives for interiors
- Produce design concepts from floor plans
Illustration and Art
- Create variations of artwork maintaining composition
- Generate style alternatives from sketches
- Produce colorizations following line art
- Transform art styles while keeping structure
Best Practices
Choosing the Right Control Type
| Goal | Recommended Control |
|---|---|
| Maintain exact shapes | Canny Edge |
| Preserve spatial layout | Depth Map |
| Keep human poses | OpenPose |
| Follow drawings | Line Art |
| Scene composition | Segmentation |
Adjusting Control Strength
Balance structure adherence with creative freedom:
- High strength (0.8-1.0): Strict structural adherence
- Medium strength (0.5-0.7): Guided but flexible
- Low strength (0.2-0.4): Loose inspiration
Combining with Prompts
Structure control works best with complementary prompts:
- Describe the style and mood you want
- Specify materials, lighting, and atmosphere
- Let the structure handle composition
- Use prompts for aesthetic direction
Multi-Control Techniques
Combine multiple control types for precise results:
- Depth + Canny for architectural precision
- Pose + Depth for character in environment
- Segmentation + Line for illustrated scenes
Structure Control vs Other Tools
| Need | Best Tool |
|---|---|
| Exact structural guidance | Structure Control |
| Style transformation | Style Transfer |
| Complete reimagining | AI Reimagine |
| Fill specific areas | AI Inpainting |
| Extend boundaries | Image Expand |
Integration with Pixelift Workflow
Pixelift's Structure Control integrates with other tools:

Technical Tips
Preparing Reference Images
- Use clear, high-contrast images for edge detection
- Ensure good lighting for depth estimation
- Position subjects clearly for pose detection
- Crop to focus on relevant structure
Troubleshooting Common Issues
- Result too rigid: Lower control strength
- Structure not followed: Increase strength or use cleaner reference
- Artifacts at edges: Try different control type
- Pose incorrect: Use clearer reference with visible joints
