Abstract:	在本文中我們提出一個能夠有效復原有霧影像的方法。透過白區塊視網膜皮層理論和改良的暗通道先驗演算法，除了獲得清晰影像，也能夠解決暗通道先驗所產生的1)光暈效應2)色彩失真3)運算時間過長的問題。並於文末比較此兩演算法的優缺點及有效性以證實本文所提出的方法的可應用性。;In this paper, we propose a simple but effective method to remove haze from a single input image using white-patch retinex and modified dark channel prior. In this way, we can not only restore the hazy images but also overcome three problems caused by dark channel prior, which are the halo effect along depth discontinuities in recovered images, the color distortion is serious in some weather conditions and the time-consuming process. Finally, we compare our proposed method with the dark channel prior and analyze their pros and cons.
