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 ]. WebJan 1, 2024 · The method of dark object subtraction assumes that dark objects reflect no light; therefore, any nonzero reflectance value must result from atmospheric scattering (Teillet and Fedosejevs, 1995 ). The method searches each band for the darkest pixel value.
