Z. Li and J. Zheng, "Single Image De-Hazing Using Globally Guided Image Filtering," in IEEE Transactions on Image Processing, vol. 27, no. 1, pp. 442-450, Jan. 2018. doi: 10.1109/TIP.2017.2750418
Local edge-preserving smoothing techniques such as guided image filtering (GIF) and weighted guided image filtering (WGIF) could not preserve fine structure. In this paper, a new globally guided image filtering (G-GIF) is introduced to overcome the problem. The proposed filter is applied to study single image haze removal. Experimental results show that fine structure of the dehazed image is indeed preserved better by the proposed G-GIF and the dehazed images by the proposed G-GIF are sharper than those dehazed images by the existing GIF.
