Production-grade quality gate for AIGC videos — not a benchmark

Project description

AIGCQA

中文 | English

AIGC 视频生产级质量门控 —— 不是学术基准,是工程工具。

AIGCQA 填补了学术基准(VBench、EvalCrafter —— 慢、重、仅限研究)与生产质量门控(快速、轻量、可组合)之间的空白。

PyPI version Python License: MIT


核心特性

  • 4 个可组合指标:人脸质量、时序一致性、手部质量、技术质量
  • 3 档后端fast(无需 GPU)/ light(消费级 GPU,CLIP-IQA + open_clip)/ full(LMM)
  • 可解释输出:不只是一个数字,精确定位到哪一帧有什么问题
  • 多格式输出:JSON / HTML(含雷达图 + 帧时间轴)
  • 多接入方式:CLI、Python API、ComfyUI 节点

安装

pip install aigcqa                # fast 后端(无需 GPU)
pip install aigcqa[light]         # + piq CLIP-IQA + open_clip 时序分析
pip install aigcqa[full]          # + LMM 解释器(Qwen2.5-1.5B-Instruct)

快速开始

from aigcqa import quick_assess

result = quick_assess("video.mp4")
print(result.passed)           # True / False
print(result.overall_score)    # 例如 82.4
print(result.recommendation)   # "建议重新生成 frames 30-67"
result.to_html("report.html")  # 含雷达图 + 帧时间轴的 HTML 报告

完整流水线

from aigcqa import QualityPipeline, FaceMetric, TemporalMetric, HandMetric, TechnicalMetric

pipe = QualityPipeline(
    metrics=[
        FaceMetric(backend="light"),
        TemporalMetric(backend="light"),
        HandMetric(backend="fast"),
        TechnicalMetric(backend="light"),
    ],
    threshold=80.0,
    weights={"face": 0.3, "temporal": 0.3, "hand": 0.2, "technical": 0.2},
)
report = pipe.run("output.mp4")
report.to_html("report.html")
print(report.to_json())

CLI

# 基础评测
aigcqa assess video.mp4

# light 后端,自定义阈值,输出 HTML
aigcqa assess video.mp4 --backend light --threshold 80 --output report.html

# JSON 输出
aigcqa assess video.mp4 --format json

# 使用 LMM 解释器
aigcqa assess video.mp4 --explainer lmm --lmm-model Qwen/Qwen2.5-1.5B-Instruct

# 批量评测整个目录
aigcqa batch ./outputs/

# 查看所有指标
aigcqa list-metrics

指标说明

指标 fast 后端 light 后端 full 后端
face OpenCV Haar + 拉普拉斯清晰度 + CLIP 零样本人脸质量 Qwen2-VL
temporal LPIPS 帧间差异 + open_clip 身份漂移检测 T2VQA
hand MediaPipe 手部检测 + 骨架几何规则校验 HandEval + CLIP
technical 亮度/曝光分析 piq CLIP-IQA FAST-VQA

后端对比

后端 速度 是否需要 GPU 精度 适用场景
fast <0.5s/帧 基础 CI 流水线、快速过滤
light ~1s/帧 消费级 GPU 中等 日常生产工作流
full ~3s/帧 多卡 最高 最终质量验收

输出格式

{
  "overall_score": 68.4,
  "passed": false,
  "threshold": 75.0,
  "source": "output.mp4",
  "metrics": {
    "face": {"score": 82.1, "issues": [...], "meta": {...}},
    "temporal": {"score": 41.3, "issues": [...], "meta": {...}}
  },
  "explanation": {
    "backend": "rule",
    "summary": "视频时序一致性存在明显问题",
    "recommendation": "建议重新生成 frames 30-45",
    "detail": "时序一致性 41分(较差);人脸质量 82分(良好)"
  }
}

LMM 解释器

from aigcqa import QualityPipeline, TechnicalMetric, FaceMetric, LMMExplainer

pipe = QualityPipeline(
    metrics=[TechnicalMetric(backend="light"), FaceMetric(backend="light")],
    explainer=LMMExplainer(model_name="Qwen/Qwen2.5-1.5B-Instruct"),
)
report = pipe.run("video.mp4")
print(report.explanation.summary)  # 自然语言质量分析

ComfyUI 集成

examples/comfyui_node.py 复制到 ComfyUI/custom_nodes/aigcqa_node.py

注册两个节点:

  • AIGCQA Quality Gate:输入 IMAGE batch → 输出分数、是否通过、报告 JSON
  • AIGCQA Report Renderer:输入报告 JSON → 输出 HTML

学术背景

  • DOVER (ICCV 2023):分离式目标视频质量评估,美学 + 技术双分支
  • HandEval (arXiv 2510.08978, 2025):首篇生成图像手部质量评估论文
  • NTIRE 2025 XGC Challenge:说话人头部质量评估,直接验证数字人质量市场需求
  • VQAThinker (2025):具备推理能力的可解释 VQA
  • AgenticIQA (2025):可解释图像质量评估的智能体框架

Roadmap

版本 状态 功能
v0.1.0 ✅ 已发布 4 指标全后端(fast/light)、规则/LMM 解释器、CLI、HTML+JSON、ComfyUI
v1.0 规划中 full 后端(FAST-VQA、LLaVA)、REST API 服务
