Auv-Based Side-Scan Sonar Real-Time Method For Underwater-Target Detection

Social Science Research Network, 2023
The limitations of underwater acoustic communications mean that the side-scan sonar data of an autonomous underwater vehicle (AUV) cannot be transmitted back and processed in real time, which means that targets cannot be detected in real time. To address

Deep Learning Algorithms for Sonar Imagery Analysis and Its Application in Aquaculture: A Review

IEEE Sensors Journal, 2023
With the rapid development of underwater sensor techniques, using acoustic techniques to obtain and analyze underwater images is an effective approach due to the superior nature of sonar, especially in turbidity and dim underwater environment.

Research on Obstacle Detection and Avoidance of Autonomous Underwater Vehicle Based on Forward-Looking Sonar

IEEE Transactions on Neural Networks and Learning Systems, 2022
Due to the complexity of the ocean environment, an autonomous underwater vehicle (AUV) is disturbed by obstacles when performing tasks. Therefore, the research on underwater obstacle detection and avoidance is particularly important.

Side-Scan Sonar Analysis Using ROI Analysis and Deep Neural Networks

IEEE Transactions on Geoscience and Remote Sensing, 2022
Side-scan sonar generates an image based on the reflection of sound waves. The reflection takes place with the first encountered object, which, in practice, may be a passing fish or even a wave from the boat turbine. Therefore, such data are sensitive to

MLFFNet: Multilevel Feature Fusion Network for Object Detection in Sonar Images

IEEE Transactions on Geoscience and Remote Sensing, 2022
Sonar image object detection is essential in underwater rescue and resource exploration. Although many convolution neural network (CNN)-based object detection algorithms have achieved great success in natural images. However, for underwater sonar images,

SONAR

2023
Accurate and comprehensive nursing documentation is essential to ensure quality patient care. To streamline this process, we present SONAR, a publicly available dataset of nursing activities recorded using inertial sensors in a nursing home. The dataset includes 14 sensor streams, such as acceleration and angular velocity, and 23 activities recorded by
