The image obtained by the traditional dark channel prior image defogging fog method is dark and the quality is not high. To solve this problem,a telegraph equation model containing bidirectional diffusion and adaptive shock filtering is established. The edge detector is combined w ith impulse filtering and the w eight coefficient is adaptively selected from the gradient feature of the image to form the sharpening term,so that the image can be enhanced adaptively according to the characteristics of different...
