摘要:

提出了一种基于噪声感知的纹理保持retinex模型的简单有效的弱光图像增强方法。新的方法,称为NATLE,试图通过一个低复杂度的解决方案,在噪声去除和自然纹理保护之间取得平衡。它的成本函数包括一个估计的分段平滑照明图和一个无噪声的纹理保持反射率图。之后,调节照明以形成增强图像以及反射率图。在常见的弱光图像增强数据集上进行了大量实验,以证明NATLE的优越性能。

英文摘要:

A simple and effective low-light image enhancement method based on a noise-aware texture-preserving retinex model is proposed in this work. The new method, called NATLE, attempts to strike a balance between noise removal and natural texture preservation through a low-complexity solution. Its cost function includes an estimated piece-wise smooth illumination map and a noise-free texture-preserving reflectance map. Afterwards, illumination is adjusted to form the enhanced image together with the reflectance map. Extensive experiments are conducted on common low-light image enhancement datasets to demonstrate the superior performance of NATLE.
