Special Issue Information

In the study of earth science and remote sensing (RS), hyperspectral images (HSIs) have received increasing attention in recent years. Compared with other types of RS images, HSIs are composed of hundreds of continuous spectral bands and contain a large amount of spatial–spectral information, which can be used to distinguish targets of different materials at the pixel level. Reliable analysis results can be applied to many remote sensing scenarios, such as agricultural management, ecological observation, etc. To date, scholars have developed a large number of methods to classify pixels in HSI into different semantics. Initially, most of them were proposed based on traditional machine learning, such as decision trees, random forests, support vector machines, etc. With the development of deep learning, many deep networks have also been proposed, such as convolutional neural networks, recurrent neural networks, etc. However, as the content of HSIs becomes richer and the application requires more and more subdivided scenes, advanced technologies still need to be explored to fully mine the effective information of HSIs.

This Special Issue encourages the submission of papers on advanced machine/deep learning and image processing techniques for hyperspectral images.

While many neural networks have been proposed for hyperspectral image classification, current backbones cannot achieve accurate results due to the insufficient representation by scalar features and always cause a cumbersome calculation burden. To solve the problem, we propose the capsule attention network (CAN), which combines an activity vector with an attention mechanism to improve HSI classification. In particular, we consider two attention mechanisms to improve the effectiveness of the activity vectors. First, an attention-based feature extraction (AFE) module is proposed to preprocess the spectral-spatial features of HSI data, which effectively mines useful information before the generation of the activity vectors. Second, we propose a self-weighted mechanism (SWM) to distinguish the importance of different capsule convolutions, which enhances the representation of the primary activity vectors. Experiments on four well-known HSI datasets have shown our CAN surpasses state-of-the-art (SOTA) methods on three widely used metrics with a much lower computational burden. Full article
