The presence of haze greatly limits the visibility of images and the acquisition of scene details, so it is particularly important to explore how to efficiently dehazed images. Based on this problem, we delve into the nature of haze imaging, model the blurred image and estimate the airlight and transmission coefficients in it, invert the dehazed image and perform image enhancement processing. In the algorithm we introduce methods to speed up the operation of the algorithm such as KD tree clustering algorithm and interpolation algorithm to reduce the complexity of the algorithm. Finally, we validate our algorithm with the official dataset REISDE and obtain very satisfactory results with an overall complexity of O(n). Therefore, our algorithm can process dehazed images very efficiently and quickly.
