The third-order cyclic cumulant spectrum, also known as the cyclic bispectrum, is derived, and its sparsity is demonstrated for an amplitude-modulated propeller noise model. Cyclic modulation bispectrum (CMBS) is proposed for the feasible approximation of the cyclic bispectrum (CB) based solely on the discrete Fourier transform. A partial Fourier basis is suggested for compressive sensing (CS) of the cyclic modulation bispectrum. The sparse recovery of this bispectrum is formulated as a multiple measurement vector problem. The proposed scheme is suitable, not only for the propeller cavitation noise, but also for general non-Gaussian cyclostationary signals. Numerical examples are given for the acquisition of propeller tonals using real-world underwater acoustic data and synthetically generated propeller noise. Sparse recovery results are compared to the second-order method for various numbers of compressive samples. It is shown that frequencies of the prominent tonals can be obtained even when sampling significantly below the Nyquist rate. The accurate estimation of the tonal magnitudes, on the other hand, is challenging even for a relatively higher number of compressive samples.","PeriodicalId":13191,"journal":{"name":"IEEE Journal of Oceanic Engineering","volume":"49 2","pages":"332-339"},"PeriodicalIF":4.1,"publicationDate":"2023-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140555860","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Contemporary PTOs developed for wave power stations are focused on the year-round averaged sea condition, leading to undesirable performance under low wave frequencies. Facing the challenge, a multicoil electromagnetic wave power takeoff (ME-PTO) with a pneumatic velocity upconversion mechanism is introduced. The new architecture features a pneumatic cylinder connected to a coiled tube to house a reciprocating permanent magnet for electricity generation, and the designed cross-sectional area differential between the magnet and piston allows for boosting the magnet speed, to deliver more capturable power. Dynamic models for the ME-PTO were established, and a numerical solution from the wave–buoy interaction to the electricity output was developed. A compact 23-mm diameter by 190 mm long prototype was built in the lab and an experimental test platform was constructed for model validation. Initial results of operation between 0.2 and 1 Hz have shown that the power density of ME-PTO can reach 72.4 W/m\u0000<sup>3</sup>\u0000 at 0.4 Hz, and is capable of extracting more wave energy compared to a baseline 50-W mechanical PTO when the incident wave is below 0.2 Hz. Under an incident wave with a peak frequency of 0.31 Hz and amplitude below 0.5 m, the cumulative work density of the ME-PTO can be three times higher than the baseline. Even at higher wave frequencies when the three-phase motor is more efficient, the ME-PTO can still exhibit comparable work density. In addition, performance indicators, such as the yearly energy output density of the prototype, have also been compared to contemporary devices, exhibiting advantages in decimeter-level wave energy extraction.","PeriodicalId":13191,"journal":{"name":"IEEE Journal of Oceanic Engineering","volume":"49 2","pages":"416-429"},"PeriodicalIF":4.1,"publicationDate":"2023-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140555886","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With the increasing demand of using MIWSNs for different applications, the need for an efficient medium access control (MAC) protocol to better utilize the available channels also increases. This article thus realizes the need for a MAC protocol for MIWSNs and presents the design and implementation of a simple and an energy-efficient MI-MAC protocol. This article first presents the design decisions and the proposed algorithm of the MI-MAC protocol. It then discusses the implementation of the MI-MAC protocol for the two possible (sequential and simultaneous) transmit configurations available with a 3-D MI transceiver. MI-MAC implementation for both sequential and simultaneous transmit configurations are evaluated for energy consumption and throughput performance. The results show that the sequential configuration outperforms the simultaneous configuration in energy efficiency by three times, whereas simultaneous configuration outperforms the sequential configuration in terms of throughput by three times. This article, therefore, presents MI-MAC implementation for a hybrid configuration to achieve optimal performance in terms of both energy efficiency and throughput.","PeriodicalId":13191,"journal":{"name":"IEEE Journal of Oceanic Engineering","volume":"49 2","pages":"572-582"},"PeriodicalIF":4.1,"publicationDate":"2023-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140555816","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, underwater imaging is subject to several factors that can severely degrade image quality, i.e., light absorption and scattering within the water column. An effective underwater image quality assessment (UIQA) metric is therefore needed to accurately quantify image quality, subsequently facilitating the follow-up of underwater vision tasks. In this article, we propose a novel feature-interaction-based UIQA framework, namely, SISC, which addresses the challenges of training data scarcity and complex underwater degradation conditions. A feature refinement module is dedicatedly designed based on self-attention to implement local and nonlocal cross-spatial feature interactions. In addition, we enhance the refined features in a cross-scale fashion using upsampling and downsampling strategies based on cross-attention. With the two stages of feature refinement and feature enhancement, the proposed SISC achieves data-efficient learning and superior performance compared to existing state-of-the-art UIQA and natural IQA (images captured in air) methods, indicating its effectiveness in extracting quality-aware features from underwater images.","PeriodicalId":13191,"journal":{"name":"IEEE Journal of Oceanic Engineering","volume":"49 2","pages":"637-648"},"PeriodicalIF":4.1,"publicationDate":"2023-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140555888","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The difficulty is partly because of the degradation of underwater images caused by light selective absorption and scattering. Intuitively, enhancing underwater images can benefit high-level applications like underwater object detection. However, it is still unclear whether all object detectors need underwater image enhancement as preprocessing. We therefore pose the questions \u0000<italic>“Does underwater image enhancement really improve underwater object detection?”</i>\u0000 and \u0000<italic>“How does underwater image enhancement contribute to underwater object detection?”</i>\u0000. With these two questions, we conduct extensive studies. Specifically, we use 18 state-of-the-art underwater image enhancement algorithms, covering traditional, CNN-based, and GAN-based algorithms, to preprocess underwater object detection data. Then, we retrain seven popular deep learning-based object detectors using the corresponding results enhanced by different algorithms, obtaining 126 underwater object detection models. Coupled with seven object detection models retrained using raw underwater images, we employ these 133 models to comprehensively analyze the effect of underwater image enhancement on underwater object detection. We expect this study can provide sufficient exploration to answer the aforementioned questions and draw more attention of the community to the joint problem of underwater image enhancement and underwater object detection. The pretrained models and results are publicly available and will be regularly updated.","PeriodicalId":13191,"journal":{"name":"IEEE Journal of Oceanic Engineering","volume":"49 2","pages":"606-621"},"PeriodicalIF":4.1,"publicationDate":"2023-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139945838","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In our solution, multiple colored stripes of structured light are projected on the surface of the object to be measured at once without the scanning process and, thus, have the advantages of high measurement accuracy, efficiency, stability, and reliability, which could realize the survey and positioning of underwater targets and guide the robotic arm to grasp the underwater targets autonomously. In this article, an underwater binocular measurement model with nonparallel and non-co-refractive surfaces is established by tracing the propagation path of light in water, and a multicolor structured light array is used to provide active visual features for the underwater object to be measured by projecting the multicolor structured light array, avoiding the limitation of the center point of monochromatic structured light, and the object could be at any position in the binocular field of view. Then, the laser strip images were separated from the background and segmented by the HSV double-threshold segmentation method; the color light stripes segmented from the left and right images were matched corresponding to their color information and position information. Finally, the feature points required for measurement are extracted from the laser stripe images taken by the left and right cameras to achieve a fast underwater survey, and through analyzing the experimental data and observing the object 3-D reconstruction effect, the effectiveness and accuracy of the underwater binocular measurement model and the underwater binocular matching algorithm established in this article are proved.","PeriodicalId":13191,"journal":{"name":"IEEE Journal of Oceanic Engineering","volume":"49 2","pages":"649-666"},"PeriodicalIF":4.1,"publicationDate":"2023-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140555884","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, traditional 2-D sub-bottom profiler (SBP) data cannot represent the 3-D shape of the buried shipwreck. An automatic shipwreck detection method based on 3-D SBP data is presented in this article. First, the key hull shape parameters are given and analyzed to describe the 3-D geometric characteristics of the shipwreck. Then, geometric contours of reflections were extracted based on 3-D SBP data by using the Enhancement Filtering Method to remove interferences, followed by applying the Global Energy Optimization Method to obtain contour clusters. After that, we elaborated on the main parameters used in hull shape description and presented the definitions of these parameters under a local coordinate system established using principal component analysis. Then, we define the shape index of the shipwreck (SI). To remove the dependence on a shipwreck attitude, we build the local coordinate system. To achieve unsupervised detection, we utilize prior information about the hull shape and determine the threshold for the SI in shipwreck detection. By applying the proposed method to both the real and simulated data, we demonstrate successful detection performance.","PeriodicalId":13191,"journal":{"name":"IEEE Journal of Oceanic Engineering","volume":"49 2","pages":"458-473"},"PeriodicalIF":4.1,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140555821","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
