WebOct 27, 2024 · Salient object detection (SOD) for optical remote sensing images (RSIs) aims at locating and extracting visually distinctive objects/regions from the optical RSIs. WebOct 22, 2024 · Typically, optical RSIs contain diverse objects and covers a wide range with complicated background, for which SOD aims to completely segment the significant objects or regions (such as airplanes, ships, rivers and stadiums). Optical remote sensing detection is often interfered by background.

WebTo tackle the challenges of RSIs including large-scale variation of objects, cluttered background, irregular shape of objects, and big difference in illumination, the cutting-edge convolutional neural network (CNN)-based models are proposed and have achieved an encouraging performance. WebJul 5, 2024 · In this paper, we propose a novel Attention Guided Network (AGNet) for SOD in optical RSIs, including position enhancement stage and detail refinement stage. Specifically, the position enhancement stage consists of a semantic attention module and a contextual attention module to accurately describe the approximate location of salient objects.
WebOct 27, 2024 · Optical RSIs have been widely used in land planning, disaster monitoring, military reconnaissance and other fields in light of its characteristics of large range, high resolution, content richness and intuitiveness. WebWe compare the proposed methods with thirteen state-of-the-art approaches on two challenging optical RSI datasets. Without bells and whistles, our method achieves the best performance under three evaluation metrics. Besides, the model has a real-time inference speed of 109 FPS. Qualitative Evaluation
WebJul 25, 2024 · All the optical RSIs for FRSM utilise either red-NIR or NDVI space except shortwave infrared soil moisture index (SIMI), which combines red, SWIR and blue bands. The thermal RSIs combine red, NIR or NDVI with land surface temperature (LST) to retrieve FRSM. Surface water content index (SWCI) combines the optical SWCI with LST to … Webdevelop the detailed design requirements for a major new lidar/optical facility to study the chemistry and dynamics of the Earth’s atmosphere from the middle stratosphere (~30 km) to well into the thermosphere (~1000 km).
