Histogram Equalization Based Cable Tunnel Image Defogging Method

The image atomization of urban cable tunnel is serious., which affects the image quality. Aiming at the atomization problem of cable tunnel image., this paper proposes a local distribution equalization algorithm., collects the typical images in cable tunnel., and analyzes the images. The defogging method of evenly distributed image is improved, and an improved method is proposed. After the image is divided into small areas., the local parameters are optimized, and the improved method is tested. The experimental results show that this algorithm can better defog the cable tunnel image.
