摘要:

扩散模型显著提升了文本到图像生成能力,能够根据文本描述生成高质量、逼真的图像。除生成之外,对象级图像编辑仍然是一个具有挑战性的问题,它要求在保持视觉一致性的同时进行精确修改。现有的基于文本指令的编辑方法难以处理局部形状和布局变换,常常引入非预期的全局变化。基于图像交互的方法虽然精度更高,但需要人工提供精确指导。为了在保持较高图像编辑精度的同时减少人工操作,本文提出了POEM,一个利用多模态大语言模型(MLLMs)进行精确对象级编辑的框架。POEM利用MLLMs分析指令提示,并在变换前后生成精确的对象掩码,从而在无需大量用户输入的情况下实现细粒度控制。这一结构化推理阶段指导基于扩散的编辑过程,确保准确的对象定位与变换。为评估所提方法,我们引入了VOCEdits,一个基于PASCAL VOC 2012构建的基准数据集,并补充了指令性编辑提示、真值变换和精确对象掩码。实验结果表明,POEM在精度和可靠性上优于现有的基于文本的图像编辑方法,同时与基于交互的方法相比减少了人工操作。

英文摘要:

Diffusion models have significantly improved text-to-image generation, producing high-quality, realistic images from textual descriptions. Beyond generation, object-level image editing remains a challenging problem, requiring precise modifications while preserving visual coherence. Existing text-based instructional editing methods struggle with localized shape and layout transformations, often introducing unintended global changes. Image interaction-based approaches offer better accuracy but require manual human effort to provide precise guidance. To reduce this manual effort while maintaining a high image editing accuracy, in this paper, we propose POEM, a framework for Precise Object-level Editing using Multimodal Large Language Models (MLLMs). POEM leverages MLLMs to analyze instructional prompts and generate precise object masks before and after transformation, enabling fine-grained control without extensive user input. This structured reasoning stage guides the diffusion-based editing process, ensuring accurate object localization and transformation. To evaluate our approach, we introduce VOCEdits, a benchmark dataset based on PASCAL VOC 2012, augmented with instructional edit prompts, ground-truth transformations, and precise object masks. Experimental results show that POEM outperforms existing text-based image editing approaches in precision and reliability while reducing manual effort compared to interaction-based methods.
