Underwater target recognition based on WPT and SVM

2010 International Conference on Computer and Communication Technologies in Agriculture Engineering, 2010
Underwater target recognition, which possesses a crucial theoretic and application value, is a very important topic in the world. The basic principles of wavelet packets transform (WPT) and support vector machine (SVM) are briefly introduced at first. Then the signals of ship radiated are pre-processed and filtered by WPT and the wavelet packets energy

Underwater object reconstruction method for target recognition in an Autonomous Underwater Vehicle

OCEANS'10 IEEE SYDNEY, 2010
We consider the problem of reconstructing 3D models of underwater objects from multiview images and propose a low complexity algorithm to achieve this without loss in accuracy as compared to existing work. We utilize bicubic interpolation as a substitute for Gaussian decomposition to arrive at multiresolution images.

Sonar automatic target recognition for underwater UXO remediation

2015 IEEE Conference on Computer Vision and Pattern Recognition Workshops (CVPRW), 2015
Automatic target recognition (ATR) for unexploded ordnance (UXO) detection and classification using sonar data of opportunity from open oceans survey sites is an open research area. The goal here is to develop ATR spanning real-aperture and synthetic aperture sonar imagery.

Underwater target recognition system based on Case-Based Reasoning

2008 3rd International Conference on Intelligent System and Knowledge Engineering, 2008
Case-based reasoning(CBR) is a recent approach to problem solving and learning. Originating in the US, the basic idea and underlying theories have spread to other continents. In this paper, A underwater target recognition system based on CBR is designed.

An Underwater Acoustic Target Recognition Method Based on Transfer Learning

2024 9th International Conference on Electronic Technology and Information Science (ICETIS)
 Underwater acoustic target recognition(UATR)is a challenging task Due to the high cost of sampling data, it is difficult to build a large-scale dataset.In this study,a new method based on transfer learning with a VGG16 model(Transfer-VGG16) is developed in which three-dimensional(3-D)data is used as the input.Use the dataset obtained in real scenarios
