Research and System Implementation of Image Defogging Technology
Regarding the problem of clarity processing for degraded images in foggy weather,various defog-ging algorithms and evaluation methods for image quality were studied and an image defogging system was de-signed and developed on MATLAB platform.By using this system,experimental studies have been conducted on global/local histogram equalization defogging algorithm,Retinex defogging algorithm,and dark channel prior de-fogging algorithm.The effectiveness of the algorithm has been confirmed through experiments,and the defogging effects of the algorithm has been objectively evaluated from three aspects:mean square error,peak signal-to-noise ratio,and structural similarity.
