ABSTRACT
In order to solve the problem of low contrast image and loss of image details in the foggy weather, the image defogging technique is used to remove the noise in the image and improve the image contrast, so as to recover a clear and fog-free image. In this paper, we mainly introduce three image defogging algorithms: global histogram equalisation, local histogram equalisation and the Retinex algorithm. The advantages and shortcomings of each algorithm are summarised through the study of the principles of each algorithm and the comparative analysis of the experimental result.
