Spectral–Spatial Feature Tokenization Transformer for Hyperspectral Image Classification

🤖 Plain-English Summary

In hyperspectral image (HSI) classification, each pixel sample is assigned to a land-cover category. Using three standard datasets, experimental analysis confirms that the computation time is less than other deep learning methods and the performance of the classification outperforms several current advanced methods.

🔑 Key Findings

• In the recent past, convolutional neural network (CNN)-based HSI classification methods have greatly improved performance due to their superior ability to represent features.
• However, these methods have limited ability to obtain deep semantic features, and as the layer’s number increases, computational costs rise significantly.
• The transformer framework can represent high-level semantic features well.
