Aesthetic Scorer

Aesthetic Scorer Skill

This skill provides comprehensive aesthetic evaluation and improvement suggestions for images and photographs through a dynamic weighted two-tier architecture.

Architecture Overview

Two Evaluation Sources with Dynamic Weight:

1. Improved Aesthetic Predictor: CLIP ViT-L/14 + MLP for content-level aesthetic scoring

   • Understands image semantics and visual impact
   • Base Weight: 45% (adjustable 45%-70% based on NIMA consensus)

2. NIMA (Neural Image Assessment): MobileNet for technical quality scoring

   • Provides detailed quality distribution and standard deviation
   • Base Weight: 55% (adjustable 30%-55% based on NIMA consensus)

Dynamic Weight Logic:

• NIMA returns a standard deviation (std) indicating score distribution spread
• High std = controversial image = more weight to IAP (content-based)
• Low std = consensus = use balanced weights

Dynamic Weight Formula

normalized_std = min(nima_std / 2.5, 1.0)
weight_iap = 0.45 + normalized_std * 0.25    // Range: 45% - 70%
weight_nima = 1.0 - weight_iap

// Penalty when scores diverge significantly (diff >= 2.0)
penalty = 0.05 * |IAP_score - NIMA_score|

weighted_score = weight_iap * IAP + weight_nima * NIMA - penalty

Evaluation Text Generation:

• The detailed evaluation text (composition, color, lighting, technical quality, improvement suggestions) is generated by the AI (WorkBuddy) based on:
  • The weighted scores from both models
  • Visual understanding of the photo content
  • Professional photography knowledge and best practices
• This provides professional-grade analysis without requiring external API calls

Workflow

Phase 1: Execute Both Evaluations

Step 1: Improved Aesthetic Predictor (dynamic weight)

1. Execute scripts/score_improved_predictor.py <image_path>
2. Parse output score (0-10 scale)
3. Record as score_improved

Step 2: NIMA Model (dynamic weight)

1. Execute scripts/score_nima.py <image_path>
2. Parse mean score AND standard deviation
3. Record as score_nima and nima_std

Phase 2: Calculate Weighted Comprehensive Score (Dynamic)

Step 2.1: Calculate Dynamic Weights

• Extract NIMA's standard deviation (std_score)
• Normalize: normalized_std = min(std_score / 2.5, 1.0)
• Calculate weights: weight_iap = 0.45 + normalized_std * 0.25

Step 2.2: Apply Penalty if Needed

• If |IAP - NIMA| >= 2.0, apply penalty: penalty = 0.05 * |IAP - NIMA|

Step 2.3: Calculate Final Score

weighted_score = weight_iap * IAP + (1-weight_iap) * NIMA - penalty

Example:

• IAP = 6.44, NIMA = 4.52, NIMA_std = 1.87
• normalized_std = 1.87/2.5 = 0.75
• weight_iap = 0.45 + 0.75×0.25 = 0.637 (63.7%)
• weight_nima = 0.363 (36.3%)
• Score_diff = 1.92 < 2.0, penalty = 0
• Final = 0.637×6.44 + 0.363×4.52 = 5.74

Security Note: All processing is 100% local - no data leaves your device

Phase 3: Generate Evaluation at Appropriate Detail Level

CRITICAL: Three Detail Levels Available

Always generate the detailed evaluation (10分) in the background first and save it. Then present the evaluation at the requested detail level:

How User Requests Different Levels:

• 默认/未指定 → 使用 3分（中等），约300字
• "详细评价" / "详细版" / "完整评价" → 使用 10分（详细），约4000字
• "简要评价" / "简洁版" / "简要说明" → 使用 1分（简要），约200字

Important:

• ALWAYS generate detailed evaluation (10分) in background first
• Save detailed evaluation so it can be retrieved immediately if user requests it
• Present the appropriate level based on user request (default: 3分)
• If user requests detailed evaluation after seeing summary, retrieve the saved detailed version
