AI总结:

针对传统动画生成成本高、内容短且连贯性差的问题,研究提出以大型多模态模型为核心的Anim-Director智能体,通过三阶段自主流程实现从文本到可控动画视频的生成,无需人工干预。

摘要:

传统动画生成方法依赖使用人工标注数据训练生成模型,需要复杂的多阶段流程,耗费大量人力且训练成本高昂。由于提示方案有限,这些方法通常生成的动画时长较短、信息匮乏且上下文不连贯。为克服这些局限并实现动画流程自动化,我们率先引入大型多模态模型(LMMs)作为核心处理器,构建了一个自主动画制作智能体,命名为Anim-Director。该智能体主要利用LMMs的高级理解与推理能力以及生成式AI工具,从简洁的叙事文本或简单指令出发创作动画视频。具体而言,它主要分三个阶段运行:首先,Anim-Director根据用户输入生成连贯的故事情节,随后生成详细的导演脚本,内容包含角色设定、室内外场景描述,以及涵盖出场角色、室内或室外场景、场景事件的上下文连贯的场景描述。其次,我们结合图像生成工具调用LMMs生成场景设定与场景的视觉图像。通过一种结合场景描述、出场角色图像与场景设定图像的视觉-语言提示方法,这些图像能够在不同场景间保持视觉一致性。第三,以场景图像为基础制作动画视频,由LMMs生成提示词来引导这一过程。整个过程具有显著的自主性,无需人工干预,LMMs可与生成工具无缝交互,生成提示词、评估视觉质量并选择最优结果以优化最终输出。

英文摘要:

Traditional animation generation methods depend on training generative models with human-labelled data, entailing a sophisticated multi-stage pipeline that demands substantial human effort and incurs high training costs. Due to limited prompting plans, these methods typically produce brief, information-poor, and context-incoherent animations. To overcome these limitations and automate the animation process, we pioneer the introduction of large multimodal models (LMMs) as the core processor to build an autonomous animation-making agent, named Anim-Director. This agent mainly harnesses the advanced understanding and reasoning capabilities of LMMs and generative AI tools to create animated videos from concise narratives or simple instructions. Specifically, it operates in three main stages: Firstly, the Anim-Director generates a coherent storyline from user inputs, followed by a detailed director's script that encompasses settings of character profiles and interior/exterior descriptions, and context-coherent scene descriptions that include appearing characters, interiors or exteriors, and scene events. Secondly, we employ LMMs with the image generation tool to produce visual images of settings and scenes. These images are designed to maintain visual consistency across different scenes using a visual-language prompting method that combines scene descriptions and images of the appearing character and setting. Thirdly, scene images serve as the foundation for producing animated videos, with LMMs generating prompts to guide this process. The whole process is notably autonomous without manual intervention, as the LMMs interact seamlessly with generative tools to generate prompts, evaluate visual quality, and select the best one to optimize the final output.
