Recent self-supervised learning (SSL) methods have demonstrated impressive results in learning visual representations from unlabeled remote sensing (RS) images. However, most RS images predominantly consist of scenographic scenes containing multiple ground objects without explicit foreground targets, which limits the performance of existing SSL methods that focus on foreground targets. This raises...Show More
Quantifying SDG11.3.1, Ratio of Land Consumption Rate to Population Growth Rate (LCRPGR), is crucial to guide decision makers in urban spatial development planning, protect the ecological environment, social and economic resources sustainability. High-precision urban built-up area data is the prerequisite for accurate calculation of land consumption rate. However, high-precision data is lacking. T...Show More
In the realm of remote sensing change detection, deep learning-based pixel-level methods have shown commendable accuracy and speed. However, due to the difficulty in distinguishing between each changed object and the high matching accuracy required, there are still limitations in practical applications. To address these issues, we propose Change DINO, a novel unified object-level change detection ...Show More
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. This “from-to” change information holds significant value in numerous practical applications and is increasingly garnering attention in the remote sensing domain. However, prevalent challenges such as los...Show More
Cities hahave a complex construction and easily affected by human activities, so they needsto be surveyed and analyzed timely. WorldView-2 high resolution remote sensing image makes it possible to study the urban land cover classification by its abundant space geometric features and spectral information. This paper would have aimed at given urban land cover types to choose suitable segmentation sc...Show More
Image segmentation is a long-term difficult problem, which hasn't been fully solved. Threshold is one of the most popular algorithms. Ant colony optimization algorithm (ACO) was recently proposed algorithm, which has been successfully applied to solve many combinatorial optimization problems. On the analysis of Ostu, we are aware that threshold selection can be viewed as a combinatorial optimizati...Show More
