Cloudmaps from static ground-view video
作者：
Highlights：
• A cloudmap represents the sunlight attenuation caused by passing clouds.
• A video of an outdoor scene is sufficient to estimate the cloudmap.
• Three approaches are proposed, each based on different geometric assumptions.
• It is possible to estimate a cloudmap even when the camera does not view the sky.
• It is not strictly necessary to directly estimate the scene geometry.
