虽然这些基于GAN的方法已经采用了一些提取空间光谱特征的策略，但是他们

Although these GAN-based approach has been used a number of tactics to extract spectral feature space, but they ignored the union between space and spectral feature extraction effectiveness and immediacy, so how to make better use of information (abundant spectral information in the HSI and detailed spatial information) still face enormous challenges.

Although these GAN-based methods have adopted some strategies for extracting spatial spectral features, they ignore the validity and immediacy of spatial and interspectral joint feature extraction, so how to make fuller use of information (rich spectral information and detailed spatial information) in HSI still faces great challenges.

Although these GaN based methods have adopted some strategies to extract spatial spectral features, they ignore the effectiveness and instantaneity of spatial and spectral joint feature extraction, so how to make full use of information (rich spectral information and detailed spatial information) in HSI is still facing a huge challenge.
