Many image processing and analysis techniques have been developed to aid the interpretation of remote sensing images and to extract as much information as possible from the images. The choice of specific techniques or algorithms to use depends on the goals of each individual project.
احصل على السعرScaling sparse data Centering sparse data would destroy the sparseness structure in the data, and thus rarely is a sensible thing to do. However, it can make sense to scale sparse inputs, especially if features are on different scales. MaxAbsScaler and maxabs scale were specifically designed for scaling sparse data, and are the recommended way to go about this.
احصل على السعرprocessing or analysis task ( background subtraction) The aim of preprocessing is to improve image data so that it suppresses undesired distortions and/or it enhances image features that are relevant for further processing
