Abstract EN
Inherent spectral characteristics of hyperspectral image (HSI) data are determined and need to be deeply mined.
A convolution neural network (CNN) model of two-dimensional spectrum (2D spectrum) is proposed based on the advantages of deep learning to extract feature and classify HSI.
First of all, the traditional data processing methods which use small area pixel block or one-dimensional spectral vector as input unit bring many heterogeneous noises.
The 2D-spectrum image method is proposed to solve the problem and make full use of spectral value and spatial information.
Furthermore, a batch normalization algorithm (BN) is introduced to address internal covariate shifts caused by changes in the distribution of input data and expedite the training of the network.
Finally, Softmax loss models are proposed to induce competition among the outputs and improve the performance of the CNN model.
The HSI datasets of experiments include Indian Pines, Salinas, Kennedy Space Center (KSC), and Botswana.
Experimental results show that the overall accuracies of the 2D-spectrum CNN model can reach 98.26%, 97.28%, 96.22%, and 93.64%.
These results are higher than the accuracies of other traditional methods described in this paper.
The proposed model can achieve high target classification accuracy and efficiency.
