Cloud detection is the process of identifying and distinguishing clouds in satellite imagery or other remote sensing data. This is important for a variety of applications, such as weather prediction, climate monitoring, and agricultural management. Cloud detection algorithms analyze various spectral and spatial characteristics of the data to differentiate between clouds and other objects or surfaces. These algorithms can be based on a variety of techniques, including thresholding, pattern recognition, and machine learning. Accurate cloud detection is essential for accurately interpreting remote sensing data and extracting meaningful information from it.
