The invention discloses a semi-
inverse method-based rapid
single image dehazing
algorithm, which comprises the following steps: In light of an atmospheric scattering model, working out an atmospheric
global illumination value by utilizing an improved semi-inverse
algorithm, wherein the robustness of the obtained atmospheric
global illumination value is stronger than that of the maximum gray value in a dark channel; secondly, fusing the edge information and the scene depth information of an image upon the characteristic of atmospheric
scattered light by taking the edge information of the image as a synthesis condition, and accurately estimating an atmospheric streamer; then, obtaining an initial restored
haze-free image according to the atmospheric scattering model; finally, performing color adjustment and detail enhancement
processing on the image after being initially dehazed to obtain a
haze-free image with strong sense of reality. The semi-
inverse method-based rapid
single image dehazing
algorithm has a very good
processing effect on depth
mutation or prospect pixels, so that a
vignetting effect is eliminated; shown by a large number of experiments, the semi-
inverse method-based rapid
single image dehazing algorithm disclosed by the invention is capable of well keeping color and detail information, is better in
automaticity and robustness, and can be further used for a video dehazing
system.
