ABSTRACT = {Multispectral images contain a large amount of spatial and spectral data
which are effective in identifying change areas. Deep feature extraction is important for multispectral image classification and is evolving as an interesting
research area in change detection. However, many deep learning framework based
approaches do not consider both spatial and textural details into account. In order
to handle this issue, a Convolutional Neural Network (CNN) based multi-feature
extraction and fusion is introduced which considers both spatial and textural features. This method uses CNN to extract the spatio-spectral features from individual channels and fuse them with the textural features. Then the fused image is
classified into change and unchanged regions. The presence of mixed pixels in
the bitemporal satellite images affect the classification accuracy due to the misclassification errors. The proposed method was compared with six state-of-theart change detection methods and analyzed. The main highlight of this method
is that by taking into account the spatio-spectral and textural information in the
input channels, the mixed pixel problem is solved. Experiments indicate the effectiveness of this method and demonstrate that it possesses low misclassification
errors, higher overall accuracy and kappa coefficient.},
