Abstract

Nowadays, tourism scenic area gradually become people to relax, one of the best place to rest, the huangshan mountain, the Yellow River and other famous scenic spots, for example, however, at present, most of the scenic area in the design of the monitoring equipment does not consider the influence of the bad weather, so under the condition of rain day, under the influence of atmospheric scattering function monitoring equipment, unable to capture the image; At the same time, monitoring equipment working for a long time, more or less there will be a certain degree of degradation. Therefore, this article on the basis of defects based on the existing scenic spot to fog, mainly focus on a single scale fog image enhancement algorithm Retinex algorithm and multiscale Retinex algorithm concept, and gives the specific process of two kinds of algorithm of Matlab programming, through the analysis judgment, evaluation and prediction, and plenty of experimental data and theoretical support, through a large number of experiments, the results prove multiscale Retinex algorithm in image contrast to the scenic spots in the fog effect is best, in the process of use in the future to the scenic spot of fog, can get the desired effect.
