Abstract:
A system for detecting clouds and cloud shadows is described. In one approach, clouds and cloud shadows within a remote sensing image are detected through a three step process. In the first stage a high-precision low-recall classifier is used to identify cloud seed pixels within the image. In the second stage, a low-precision high-recall classifier is used to identify potential cloud pixels within the image. Additionally, in the second stage, the cloud seed pixels are grown into the potential cloud pixels to identify clusters of pixels which have a high likelihood of representing clouds. In the third stage, a geometric technique is used to determine pixels which likely represent shadows cast by the clouds identified in the second stage. The clouds identified in the second stage and the shadows identified in the third stage are then exported as a cloud mask and shadow mask of the remote sensing image.

Claim (Index 1):
A method comprising:\n receiving remote sensing imagery of a geographical area, wherein the remote sensing imagery includes a plurality of pixels and one or more band values for each pixel within the remote sensing imagery; identifying one or more clouds within the remote sensing imagery based on a cloud mask; identifying one or more potential shadow pixels within the remote sensing imagery based on the one or more band values for each pixel within the remote sensing imagery; for each cloud of the one or more clouds, determining an optimal height of the cloud based on a geometric relationship between a satellite which captured the remote sensing imagery and a sun based on the one or more potential shadow pixels; for each cloud of the one or more clouds, identifying one or more shadow pixels within the remote sensing imagery representing a shadow cast by the cloud based on the optimal height of the cloud; generating a shadow mask that identifies shadows cast by the one or more clouds within the remote sensing imagery based on the one or more shadow pixels identified for each cloud of the one or more clouds.
