摘要:

基于深度学习的图像增强方法在低光条件下降低噪声和提升可见性方面显示出显著优势。这些方法通常基于一对一映射,模型学习从低光图像到特定增强图像的直接变换。因此,这些方法缺乏灵活性,因为它们不允许高度个性化的映射,尽管个人的光照偏好本质上是高度个性化的。为克服这些局限性,我们提出了一项新的光照增强任务和一个新框架,通过提示驱动、语义级和定量亮度调整提供定制化光照控制。该框架首先利用大语言模型(LLM)理解自然语言提示,使其能够识别需要进行亮度调整的目标对象。为定位这些目标对象,基于Retinex的推理分割(RRS)模块利用反射图像生成精确的目标定位掩码。随后,基于文本的亮度可控(TBC)模块根据生成的照度图调整亮度水平。最后,自适应上下文补偿(ACC)模块整合多模态输入并控制条件扩散模型来调整光照,确保实现无缝且精确的增强。在基准数据集上的实验结果表明,我们的框架在提升可见性、保持自然色彩平衡以及增强细节而不产生伪影方面具有优越性能。此外,其强大的泛化能力能够在多样化的开放世界环境中通过自然语言交互实现复杂的语义级光照调整。

英文摘要:

Deep learning-based image enhancement methods show significant advantages in reducing noise and improving visibility in low-light conditions. These methods are typically based on one-to-one mapping, where the model learns a direct transformation from low light to specific enhanced images. Therefore, these methods are inflexible as they do not allow highly personalized mapping, even though an individual's lighting preferences are inherently personalized. To overcome these limitations, we propose a new light enhancement task and a new framework that provides customized lighting control through prompt-driven, semantic-level, and quantitative brightness adjustments. The framework begins by leveraging a Large Language Model (LLM) to understand natural language prompts, enabling it to identify target objects for brightness adjustments. To localize these target objects, the Retinex-based Reasoning Segment (RRS) module generates precise target localization masks using reflection images. Subsequently, the Text-based Brightness Controllable (TBC) module adjusts brightness levels based on the generated illumination map. Finally, an Adaptive Contextual Compensation (ACC) module integrates multi-modal inputs and controls a conditional diffusion model to adjust the lighting, ensuring seamless and precise enhancements accurately. Experimental results on benchmark datasets demonstrate our framework's superior performance at increasing visibility, maintaining natural color balance, and amplifying fine details without creating artifacts. Furthermore, its robust generalization capabilities enable complex semantic-level lighting adjustments in diverse open-world environments through natural language interactions.
