[0022] The present invention will be described in more detail below with reference to the accompanying drawings.
[0023] The method proposed by the invention includes four steps of image preprocessing, feature extraction, space-spectral feature fusion and classification. The specific analysis steps are as follows:
[0024] Step S1: image preprocessing. The training set and test set required by the two branches are selected and normalized. This step further includes the following steps:
[0025] Step S1.1: Select the experimental platform (i5 kernel, 2.70-GHz processor), and configure the experimental environment (Theano, Keras).
[0026] Step S1.2: Correcting, denoising, labeling, and normalizing the hyperspectral remote sensing images collected by the imaging spectrometer.
[0027] Step S1.3: Prepare data for the dual-branch deep structure (the input of the spectral feature extraction branch is a pixel, and the input of the spatial feature extraction branch is an image b...
