Laser illumination nighttime image Dark Channel Prior dehazing algorithm

The dehazing algorithm based on the dark channel prior theory is a widely used dehazing method. Despite successfully enhancing clarity in foggy images, it still has some limitations such as its effectiveness diminishes when images turn grayscale, indicating an indistinct dark channel in the scene. Based on the fundamentals of the dark channel prior dehazing algorithm, an improved dehaze algorithm called LINTI-DCP, tailored for laser illumination nighttime images was developed. LINTI-DCP can overcome the inaccurate estimation of atmospheric light and transmission rates in foggy infrared laser night vision. Experimental results demonstrated that LINTI-DCP is an effective dehazing algorithm for laser illumination nighttime images.
