Semantic Information Collaboration Network for Semantic Change Detection in Remote Sensing Images

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Semantic change detection (SCD) extends the traditional change detection (CD) task to simultaneously identify the change areas and their corresponding land cover categories in bi-temporal images.

Semantic enhancement and change consistency network for semantic change detection in remote sensing images

International Journal of Digital Earth
Semantic Change Detection (SCD) identifies binary change information and determines the ‘from-to’ types, revealing not only ‘where’ changes occurred but also ‘what’ the changes are.

Multitask Siamese Network Guided by Enhanced Change Information for Semantic Change Detection in Bitemporal Remote Sensing Images

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Semantic change detection (SCD) represents a challenging task in the interpretation of remote sensing images (RSIs), with the goal of identifying change regions and extracting semantic information from bitemporal RSIs simultaneously.

DreamCD: A change-label-free framework for change detection via a weakly conditional semantic diffusion model in optical VHR imagery

International Journal of Applied Earth Observations and Geoinformation
The Earth is experiencing continuous anthropogenic and natural changes. Very high resolution (VHR) remote sensing imagery-based change detection provides an effective means to monitor these dynamics at fine spatial scales.

Detecting semantic changes from VHR remote sensing images by integrating semantic correlations and change priors

International Journal of Applied Earth Observations and Geoinformation
Investigating semantic change detection (SCD) is critical for tracking the evolution of urban and rural conversion. However, existing methods applied to SCD face two pivotal challenges: (1) modeling of semantic correlations among bi-temporal features is ...

Spatial-Temporal Semantic Feature Interaction Network for Semantic Change Detection in Remote Sensing Images

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Semantic Change Detection (SCD) in Remote Sensing Images (RSI) aims to identify changes in the type of Land Cover/Land Use (LCLU). The “from-to” information of the acquired image has more profound practical significance than Binary Change ...

MAA-SFENet: multi-head adaptive attention and spatial feature enhancement network for remote sensing images semantic change detection

Geocarto International
Semantic change detection (SCD) analyzes multi-temporal remote sensing images to identify semantic differences in ground objects. However, existing methods struggle to delineate small-scale changes and preserve fine-grained spatial structures due to ...
