- Abstract: Hyperspectral change detection plays an essential role of monitoring the
dynamic urban development and detecting precise fine object evolution and
alteration. In this paper, we have proposed an original Efficient
Multi-temporal Self-attention Network (EMS-Net) for hyperspectral change
detection. The designed EMS module cuts redundancy of those similar and
containing-no-changes feature maps, computing efficient multi-temporal change
information for precise binary change map. Besides, to explore the clustering
characteristics of the change detection, a novel supervised contrastive loss is
provided to enhance the compactness of the unchanged. Experiments implemented
on two hyperspectral change detection datasets manifests the out-standing
performance and validity of proposed method.

We propose a novel framework for remote sensing image change captioning, guided by Key Change Features and Instruction-tuned (KCFI)
KCFI includes a ViTs encoder for extracting bi-temporal remote sensing image features, a key feature perceiver for identifying critical change areas, and a pixel-level change detection decoder.
To validate the effectiveness of our approach, we compare it against several state-of-the-art change captioning methods on the LEVIR-CC dataset.
