Abstract:

In the foggy condition captured image is seriously degraded, we propose a fast image defogging algorithm based on YUV color space. Based on atmospheric scattering model, firstly the luminance is extracted, geting the scattering light after Gauss filter; then the maximum brightness value of the image as the atmospheric airlight; then can obtain a clear image. The experimental results show that the algorithm effectively improves the image quality, and can keep good image details.
