“…Unfortunately, the 2D difference matrix is a symmetric matrix, so there is at least half of the invalid information for the detection model. Detection accuracy degradation caused by the ability of the detection model in terms of difference feature capture [11, 19]. Change feature capture techniques based on traditional methods (e.g., improved change vector analysis (ICVA) [20]) and deep learning (DL) (e.g., convolutional neural networks (CNN) [21]) methods are often seen in HSI‐CD tasks in recent years. The former aims to use hand‐crafted features for change identification of bitemporal HSIs, while the latter employs a data‐driven approach to detect changing pattern at the semantic‐level feature.…”

“…Over the past 10 years, the DL methods and their variants, such as the CNN [21,22], recurrent neural network (RNN) [23], autoencoder [9,24], graph convolutional network (GCN) [25], residual network (ResNet) [26], principal component analysis network (PCANet) [27], etc., have emerged in the HSI-CD fields. In particular, the CNN-based HSI-CD framework is favoured by researchers due to its universality and portability [28].…”

“…However, these methods cannot completely remove the influence of noise in the process of CD, so scholars have proposed some new methods for the generation of DI, such as stacked autoencoders (SAEs) [19] and deep pyramid feature learning networks (DPFL-Nets) [20]. Moreover, multiscale decomposition of DI is also a common method, such as principal component analysis (PCA) [21], nonsubsampled shearlet transform (NSST) [18], discrete 3D-wavelet transform (3-DWT) [22], and scale-invariant feature transform (SIFT) [23]. Although these methods can better overcome the influence of noise, the disadvantage is that the algorithm runs for a long time.…”

“…1) Firstly, multi-temporal remote sensing images are preprocessed to provide high-quality data input (correction, enhancement, and registration [21] of original data, etc.) 2) Secondly, feature extraction and selection (spectral, spatial, object and scene) can be carried out [22], [23]. In this process, feature fusion [24] at different levels can be carried out, which is related to the change detection algorithm model.…”
