  • Publication number: 20230186606
    Abstract: Provided is a method for feature extraction of a remote sensing image based on tensor collaborative graph discriminant analysis, including: taking each of pixels as a center for intercepting a three-dimensional tensor data block; dividing experimental data into a training set and a test set in proportion; computing a Euclidean distance between a current training pixel and each class of training data; configuring a L2 norm collaborative representation model with a weight constraint; acquiring a projection matrix of each dimension of each of the three-dimensional tensor data block; and utilizing a low-dimensional projection matrix to obtain a training set and a test set, expanding the training set and the test set into a form of column vectors according to a feature dimension, inputting extracted low-dimensional features into a support vector machine classifier for classification, to determine a class of the test set, and evaluating, by a classification effect, performance of feature extraction.
