Abstract
Techniques for cloud detection and cloud coverage determination are described herein. The disclosed techniques include detecting a plurality of color clusters among a plurality of data elements of an image, associating at least one of the plurality of color clusters with a cloud based on a characteristic color of the cloud, and determining a number of data elements within the at least one of the plurality of color clusters associated with the cloud. The disclosed techniques also include detecting a location of an object indicative of a cloud in the image based at least in part on training data and a plurality of features extracted from the image, detecting an edge of the object indicative of the cloud at the location, and determining a number of data elements within the edge of the object indicative of the cloud.
