摘要

在恶劣天气下获得的图像，如雾霾，可能对比度较低，特别是在图像的顶部。技术上的挑战是逆转这一过程——只提供“雾蒙蒙”的场景，估计由于光学散射的贡献，从而恢复原始场景。这对于一般的平场场景和前视相机是可能的，尽管由于噪声影响存在一些限制。

Mitigation of atmospheric contrast degradation via image enhancement

Images obtained in bad weather such as haze, fog may have low contrast, particularly towards the top of the image. The technical challenge is to reverse this process - provided with just the “foggy” scene, estimate the contribution due to optical scattering and so recover the original scene. This is possible for a general flat-field scene and a forward-looking camera, although there are some limitations due to noise effects.
