AI总结:

针对传统视频编辑评估指标的不足,研究提出融合VLM、目标检测等技术的SST-EM框架,从语义、空间、时间多维度全面评估视频编辑效果。

摘要:

视频编辑模型已取得显著进展,但评估其性能仍具挑战性。传统指标(如CLIP文本分数和图像分数)往往存在不足:文本分数受训练数据不足和层级依赖的限制,而图像分数无法评估时间一致性。我们提出SST-EM(语义、空间与时间评估指标),这是一种新颖的评估框架,利用现代视觉语言模型(VLM)、目标检测和时间一致性检查实现评估。SST-EM包含四个组件:(1)使用VLM从帧中提取语义,(2)通过目标检测进行主要目标跟踪,(3)借助LLM智能体进行聚焦目标优化,(4)采用视觉Transformer(ViT)评估时间一致性。这些组件被整合为一个统一指标,其权重由人类评估和回归分析得出。SST-EM的名称体现了其聚焦于视频评估的语义、空间和时间维度。SST-EM可对视频编辑中的语义保真度和时间平滑性提供全面评估,源代码已在GitHub仓库公开。

英文摘要:

Video editing models have advanced significantly, but evaluating their performance remains challenging. Traditional metrics, such as CLIP text and image scores, often fall short: text scores are limited by inadequate training data and hierarchical dependencies, while image scores fail to assess temporal consistency. We present SST-EM (Semantic, Spatial, and Temporal Evaluation Metric), a novel evaluation framework that leverages modern Vision-Language Models (VLMs), Object Detection, and Temporal Consistency checks. SST-EM comprises four components: (1) semantic extraction from frames using a VLM, (2) primary object tracking with Object Detection, (3) focused object refinement via an LLM agent, and (4) temporal consistency assessment using a Vision Transformer (ViT). These components are integrated into a unified metric with weights derived from human evaluations and regression analysis. The name SST-EM reflects its focus on Semantic, Spatial, and Temporal aspects of video evaluation. SST-EM provides a comprehensive evaluation of semantic fidelity and temporal smoothness in video editing.
