...We compared the proposed model with several stateof-the-art dehazing methods: Fast Visibility Restoration (FVR) [25], Dark-Channel Prior (DCP) [8], Boundary Constrained Context Regularization (BCCR) [12], Automatic Atmospheric Light Recovery (ATM) [22], Color Attenuation Prior (CAP) [32], Non-local Image Dehazing (NLD) [1], DehazeNet [3], and MSCNN [17]....

...DCP, BCCR, ATM, NLD, and MSCNN produce un- realistic color tones on one or several images, such as DCP, BCCR and ATM results on the second row (notice the sky color), or BCCR, NLD and MSCNN results on the fourth row (notice the stone color)....

...Despite the challenge of estimating many physical parameters from a single image, many recent works have made significant progress towards this goal [1, 3, 17]....
