Research on physics-guided image luminance enhancement neural network
针对低照度图像亮度不足以及噪声、色偏难以同时校正的问题,本研究提出一种基于物理引导的图像亮度增强神经网络.该方法在线性空间中分解图像的亮度与色度,以少量超参数控制的单调色调曲线构成物理主干网络,残差网络仅学习幅度受限的局部补偿,并将多种物理一致性软约束引入作为损失函数的一部分.在低照度街景数据集上的实验结果显示,该神经网络在多种指标上均具有较优表现.研究证实,将可解释的物理模型与数据驱动的神经网络相结合,能显著提升图像亮度增强结果的自然度与稳定性,为跨场景应用提供技术基础.
To address the challenges of insufficient brightness and the difficulty of simultaneously correcting noise and color deviation in low-light images,this paper proposes a physics-guided image luminance enhancement neural network.The proposed method decomposes the image into luminance and chrominance components within a linear space,and forms a physical backbone with a monotonic tone curve controlled by a few hyperparameters,while a residual network learns only amplitude-limited local compensation.Furthermore,multiple physical constraints are introduced as loss functions.Experi-mental results on a low-light street scene dataset demonstrate that the model achieves superior performance.The re-search confirms that combining interpretable physical models with data-driven models significantly improves the natural-ness and stability of the enhancement results.Meanwhile,it provides a technical foundation for cross-scenario applications.
