新方法指导视频模型以实现更好的构图

研究人员推出了一种名为 CVG 的新方法,以增强文本到视频扩散模型的构图理解能力。该技术在推理时运行,通过利用模型内部的交叉注意力图来指导去噪过程。通过在这些注意力特征上训练一个轻量级分类器,CVG 可以引导视频生成朝着所需的构图方向发展,而无需更改底层模型架构或用户提供的控件。实验表明,在构图基准测试中,提示的忠实度和视觉质量得到了提高。 AI

影响 增强了文本到视频模型中的构图理解能力,有可能提高真实感和对复杂提示的遵循程度。

    Compositional Video Generation via Inference-Time Guidance

    Text-to-video diffusion models generate realistic videos, but often fail on prompts requiring fine-grained compositional understanding, such as relations between entities, attributes, actions, and motion directions. We hypothesize that these failures need not be addressed by retr…
