WebSatellite Image Time Series (SITS) is a data set that includes satellite images across several years with a high acquisition rate. Radiometric normalization is a fundamental and important preprocessing method for remote sensing applications using SITS due to the radiometric distortion caused by noise between images. Normalizing the subject image based on the … Web3 The greedy algorithm The greedy algorithm (henceforth referred to as Greedy) is a natural heuristic for maximizing a monotone submodular function subject to certain constraints. In several settings it provides good approximation ratios, and until quite recently, the approximation ratios provided by Greedy were the best known in most cases.
