Embodiment
[0105] The training data and test data come from the Indian Pines dataset on the GIC website. The dataset contains 224 bands, the spectral coverage range is 0.4-2.5μm, the spatial resolution is 20m, and the image size is 145*145pix. After removing 4 severely damaged bands and 20 water-absorbed bands, there are 200 bands remaining, including 16 types of ground objects. The data set contains a total of 10249 effective samples of size (200*1*1), the training set contains 517 samples, and the test set contains the remaining 9732 samples.
[0106] In this example,
[0107] Specific steps are as follows:
[0108] Step 1: First, normalize the hyperspectral image data, randomly extract 517 samples and their category labels from the valid samples of the labeled dataset IndianPines as the training set, and send the training samples and their labels to the ACGAN model for training , the ACGAN model includes a generator and a discriminator, both of which are convolutional neural network...
