WebApr 1, 2024 · One of the most effective atmospheric correction methods is dark-object subtraction (DOS) method, where the atmospheric offset can be generated from the image itself. The success of DOS strongly relies on the availability and quality of the dark target. WebJul 20, 2024 · Dark Object Subtraction (DOS) is a widely used and well-known simple image-based absolute atmospheric correction method. This approach assumes that there are at least a few pixels of dark objects throughout a satellite image scene, and they should have zero value, along with a horizontally homogeneous atmosphere [ 4, 5 ].
