# Simplified IRE Shadow Analysis Outputs
|
|
|
|
## Overview
|
|
|
|
The IRE shadow analysis has been simplified to provide only the essential outputs needed for practical use, removing unnecessary complexity and reducing the number of output parameters.
|
|
|
|
## Simplified Output Structure
|
|
|
|
### **Original Outputs (Unchanged)**
|
|
- `x_direction` - Horizontal light direction
|
|
- `y_direction` - Vertical light direction
|
|
- `combined_direction` - Overall light direction
|
|
- `hard_soft_index` - Light hardness classification
|
|
- `x_confidence`, `y_confidence` - Direction confidence values
|
|
- `overall_confidence` - Overall analysis confidence
|
|
- `spread_value` - Normal distribution spread
|
|
- `debug_mask` - Analysis area mask
|
|
- `lit_normals_viz` - Lit normals visualization
|
|
- `cluster_delta_chart` - Direction analysis chart
|
|
- `x_threshold_preview`, `y_threshold_preview` - Threshold visualizations
|
|
|
|
### **IRE Analysis Outputs (Simplified)**
|
|
- `false_color_ire` - IRE false color visualization (masked)
|
|
- `shadow_mask` - Detected shadow areas
|
|
- `soft_shadow_mask` - Soft shadow areas only
|
|
- `shadow_character` - Shadow classification text
|
|
- `transition_quality` - Transition quality description
|
|
- `soft_ratio` - Ratio of soft shadows (0.0-1.0)
|
|
- `hard_ratio` - Ratio of hard shadows (0.0-1.0)
|
|
|
|
## Removed Outputs
|
|
|
|
The following outputs were removed to simplify the interface:
|
|
|
|
### **Removed IRE Visualizations**
|
|
- `hard_shadow_mask` - Redundant with soft_shadow_mask
|
|
- `ire_legend` - Not essential for analysis
|
|
|
|
### **Removed Text Classifications**
|
|
- `ire_range` - IRE value range text
|
|
- `shadow_coverage` - Shadow coverage description
|
|
- `gradient_analysis` - Gradient analysis description
|
|
|
|
### **Removed Numerical Metrics**
|
|
- `mean_ire` - Average IRE value
|
|
- `shadow_percentage` - Percentage of shadow pixels
|
|
- `mean_gradient` - Average gradient magnitude
|
|
|
|
### **Removed Combined Analysis**
|
|
- `final_shadow_character` - Combined shadow character
|
|
- `final_light_quality` - Combined light quality
|
|
- `combined_confidence` - Combined confidence score
|
|
- `analysis_consistency` - Analysis consistency metric
|
|
|
|
## Benefits of Simplification
|
|
|
|
### **1. Cleaner Interface**
|
|
- Reduced from 19 IRE outputs to 7 essential outputs
|
|
- Easier to understand and use
|
|
- Less overwhelming for users
|
|
|
|
### **2. Focused Analysis**
|
|
- Keeps only the most useful information
|
|
- Removes redundant or overly technical outputs
|
|
- Maintains core functionality
|
|
|
|
### **3. Better Performance**
|
|
- Fewer calculations and memory usage
|
|
- Faster processing
|
|
- Reduced complexity
|
|
|
|
## Essential Outputs Explained
|
|
|
|
### **Visual Outputs**
|
|
- **`false_color_ire`**: Shows IRE analysis with false colors (masked to analysis area)
|
|
- **`shadow_mask`**: Binary mask of all detected shadow areas
|
|
- **`soft_shadow_mask`**: Binary mask of soft shadow areas only
|
|
|
|
### **Text Classifications**
|
|
- **`shadow_character`**: "Very Soft", "Soft", "Medium-Hard", "Hard", or "Mixed"
|
|
- **`transition_quality`**: "Very Gradual", "Gradual", "Moderate", "Sharp", or "Very Sharp"
|
|
|
|
### **Numerical Ratios**
|
|
- **`soft_ratio`**: Proportion of soft shadows (0.0 = no soft shadows, 1.0 = all soft)
|
|
- **`hard_ratio`**: Proportion of hard shadows (0.0 = no hard shadows, 1.0 = all hard)
|
|
|
|
## Usage Examples
|
|
|
|
### **Basic Shadow Analysis**
|
|
```python
|
|
# Get essential shadow information
|
|
shadow_character = "Soft" # From shadow_character output
|
|
transition_quality = "Gradual" # From transition_quality output
|
|
soft_ratio = 0.75 # 75% soft shadows
|
|
hard_ratio = 0.25 # 25% hard shadows
|
|
```
|
|
|
|
### **Visual Analysis**
|
|
```python
|
|
# Use visual outputs for analysis
|
|
false_color_ire # Shows IRE analysis in false colors
|
|
shadow_mask # Shows all shadow areas
|
|
soft_shadow_mask # Shows only soft shadow areas
|
|
```
|
|
|
|
## Migration from Full Outputs
|
|
|
|
If you were using the full output set, here's how to adapt:
|
|
|
|
### **For Shadow Classification**
|
|
- **Before**: Used `final_shadow_character`
|
|
- **Now**: Use `shadow_character`
|
|
|
|
### **For Light Quality**
|
|
- **Before**: Used `final_light_quality`
|
|
- **Now**: Use `soft_ratio` and `hard_ratio` values
|
|
|
|
### **For Confidence**
|
|
- **Before**: Used `combined_confidence`
|
|
- **Now**: Use `overall_confidence` from original outputs
|
|
|
|
## Conclusion
|
|
|
|
The simplified output structure provides all the essential information needed for IRE shadow analysis while removing unnecessary complexity. This makes the system more user-friendly and easier to integrate into workflows while maintaining full analytical capability.
