CHARACTER-DISTINCTIVENESS-QC
主角存在感评估器 评估"像不像主角"支持单图评分和跨镜一致性对比
功能:
1. 输入角色图片 + 参考资产包
2. OpenCV 计算轮廓颜色面部一致性
3. 跨镜一致性对比同角色多镜变化检测
4. 输出 JSON 报告 + 存在感评分 (0-10)
用法:
python character-distinctiveness-qc.py --image test.png --character CHAR-003-SuBai
python character-distinctiveness-qc.py --batch test/images/ --character CHAR-003-SuBai
python character-distinctiveness-qc.py --cross-shot shot01.png shot02.png --character CHAR-003-SuBai
