As spatial resolution increases, the information conveyed by remote sensing images becomes more and complex. Large-scale variation highly discrete distribution of objects greatly increase challenge semantic segmentation task for images. Mainstream approaches usually use implicit attention mechanisms or Transformer modules to achieve global context good results. However, these fail explicitly extract intra-object consistency inter-object saliency features leading unclear boundaries incomplete...

The rapid and accurate detection of road cracks is great significance for health monitoring, but currently, this work mainly completed through manual site surveys. Low-altitude UAV remote sensing can provide images with a centimeter-level or even subcentimeter-level ground resolution, which provides new, efficient, economical approach crack detection. Nevertheless, networks face challenges such as edge blurring misidentification due to the heterogeneity complexity background. To address...

Remote sensing (RS) images are widely used in civilian and military fields. With the highly increasing image data, it has become a challenging issue to achieve fast efficient RS retrieval. However, existing retrieval methods, text-based or content-based, still limited applications; for example, text input is inefficient, sample query often unavailable. It known that speech natural convenient way of communication. Therefore, novel speech-image cross-modal approach, named deep visual-audio...

With the improvement of spatial resolution, conveyed information remote sensing images has become increasingly intricate. The semantic content pixels within same object exhibits considerable variability, while between different objects significant overlap. However, most existing approaches focus solely on establishing internal consistency by aggregating global or multi-scale contextual without adequately considering orientation and spatially detailed features target. Moreover, these methods...
