Gray-Scale Image Dehazing Guided by Scene Depth Information

Figure 5

The process of gray-scale image dehazing by proposed method. (a) Original gray-scale hazy image. (b) Low frequency layer. (c) Enhanced image of (b). (d) High frequency layer in horizontal direction. (e) Enhanced image of (d). (f) Dehazing result with the image of scene depth proportion. (g) Dehazing result using modified guided image filtering directly.
