Expressway visibility estimation based on image entropy and piecewise stationary time series analysis

8 Apr 2018 Xiaogang Cheng Guoqing Liu Anders Hedman Kun Wang Hai-Bo Li

Vision-based methods for visibility estimation can play a critical role in reducing traffic accidents caused by fog and haze. To overcome the disadvantages of current visibility estimation methods, we present a novel data-driven approach based on Gaussian image entropy and piecewise stationary time series analysis (SPEV)...
