Hardy Variation Framework for Restoration of Weather Degraded Images

Figure 8

Specific factorization steps of two methods on aviation image. He’s algorithm is on the top row: (a) the dark channels, (b) the transmission maps obtained by guided filter, and (c) the dehazed image. The proposed algorithm is shown on the second row: (d) rough estimates maps by morphological operation, (e) the refined transmission map, and (f) the restoration image.
