摘要

由于能见度严重受损和物体颜色扭曲，在大雾遮挡的环境中导航构成了重大挑战，尤其是对驾驶辅助系统等先进技术而言。为了解决这个问题，据我们所知，我们进行了一项新的研究，研究了受控人工雾室中的颜色退化，系统地改变了雾的深度（30-70厘米）和密度（以55-300厘米的MOR表示），使用具有各种色块的立方体作为颜色目标。为了恢复雾图像中的颜色，我们开发了一种混合单图像去雾技术，该技术独特地结合了实验推导的、依赖于莫尔的颜色衰减模型。

Experimental approach to single-image dehazing and color restoration of foggy scenes.

Navigating fog-obscured environments poses a significant challenge, especially for advanced technologies like driver-assistance systems, due to severely impaired visibility and distorted object colors. To address this, we conducted, to our knowledge, a novel study investigating color degradation in a controlled artificial fog chamber, systematically varying fog depth (30-70 cm) and density (expressed in MOR of 55-300 cm) using a puzzle cube featuring a variety of color blocks as a color target. To restore color in foggy images, we developed a hybrid single-image dehazing technique uniquely incorporating experimentally derived, MOR-dependent color decay models.
