Fog Image Sharpening Based on Neural Network
Xingbo Sun · Video Engineering · 2012
The back propagation neural network structure and image degradation model based on atmospheric modulation transfer system are analyzed in this paper.We get a BP model of the atmospheric modulation transfer inverse system by the relationship of the image frequency spectrum extracted from an image in fog and the one in good weather condition in the same background.By determining the weights of network,the bad weather effects can be eliminated and the fog image can be sharpened.
