Small object detection (SOD) in optical images and videos is a challenging problem that even state-of-the-art generic object detection methods fail to accurately localize and identify such objects. Typically, small objects appear in real-world due to large camera-object distance. Because small objects occupy only a small area in the input image (e.g., less than 10%), the information extracted from such a small area is not always rich enough to support decision making. Multidisciplinary strategies are being developed by researchers working at the interface of deep learning and computer vision to enhance the performance of SOD deep learning based methods. In this paper, we provide a comprehensive review of over 160 research papers published between 2017 and 2022 in order to survey this growing subject. This paper summarizes the existing literature and provide a taxonomy that illustrates the broad picture of current research. We investigate how to improve the performance of small object detection in maritime environments, where increasing performance is critical. By establishing a connection between generic and maritime SOD research, future directions have been identified. In addition, the popular datasets that have been used for SOD for generic and maritime applications are discussed, and also well-known evaluation metrics for the state-of-the-art methods on some of the datasets are provided. © 2022, CC BY-NC-SA.

Managing a large volume of multimedia data, which contain various modalities (visual, audio, and text), reveals the need for a specialized multimedia database system (MMDS) to efficiently model, process, store and retrieve video shots based on their semantic content. This demo introduces METU-MMDS, an intelligent MMDS which employs both machine learning and database techniques. The system extracts semantic content automatically by using visual, audio and textual data, stores the extracted content in an appropriate format and uses this content to efficiently retrieve video shots. The system architecture supports various multimedia query types including unimodal querying, multimodal querying, query-by-concept, query-by-example, and utilizes a multimedia index structure for efficiently querying multi-dimensional multimedia data. We demonstrate METU-MMDS for semantic data extraction from videos and complex multimedia querying by considering content and concept-based queries containing all modalities. © Springer International Publishing Switzerland 2016.

The challenges which stood as an obstacle to the naval force development are discussed. The main challenge in the national security environment is to be virtually available anywhere in the world at the behest of the national command. It is observed that in surface warefare coast guard has the most applicability and expansion of their surveillance area will help in engaging other vessels away from the manned platform. It is also observed that the relationship with mission modularity and the growth between the coast guard and the navy has attracted interest among the international community.

This paper defines, develops and examines a set of generic analysis tools that can be applied to Models and Simulations at the systems Engineering level of fidelity. The tools examine the performance and effectiveness of Sensors;Weapons;and Battle Management, command, control, Communications, Computers, and Intelligence ((BMCI)-I-4) systems and equipment. The Measures of Performance (MOPs), Measures of Effectiveness (MOEs) and Measures of Force Effectiveness (MOFEs) were extracted from the Modular command and control Structure Paradigm which was developed at the Naval Postgraduate School. The paradigm provides for the development of evaluation criteria (MOPs, MOEs, and MOFEs) in a framework that ensures the traceability of system performance and effectiveness to the system operational requirements as specified in the Operational Requirements Document (ORD). Also, the analysis tools provide insight and valid estimates of numerical measures of the defined system functionality threads, which represent the system's operational requirements as specified in the ORD. The tools are directly transferrable and applicable to test and evaluation exercise events which are conducted in support of the development and acquisition of systems and equipment. Once the levels of system performance have been defined, the Paradigm generates a quantitative database that becomes a useful tool in system tradeoffs and selection. Once the alternative system suites have been defined, the suites can be analyzed in terms of system functionality threads and their corresponding performance capabilities versus cost.

The Fleet continues to require high performance systems that can operate with dependability in the seas' unforgiving environments and under hostile action. Those demands are not new. What has changed is the urgent priority formerly assigned to national defense issues. The arguments for continued superpower military strength are now roiled in politics along with unsettled budgets and uncertain force level projections. Current expectations revolve about indefinite fiscal and operational issues (difficult funding constraints and broadband threats). In the actual event of ''doing more with less,'' a practical response is to apply the creative power available from sound engineering judgement and the crucible of experience to the immediate needs of the Fleet. The attempt to shorten the path between advanced development effort and Fleet use has been tried occasionally in the past, often, without exemplary results. The Sustainable Hardware and Affordable Readiness Practices (SHARP) program, is a generic R&D effort under OpNav sponsorship that has been working steadily on sensible solutions to product engineering problems. Armed today with fast-time, large-scale computation abilities and modern tools for technical problem solving coupled with specialized engineering knowledge, it has been refreshed and is underway satisfying existing Fleet needs. The relationship between fully responsive engineering services and current operational needs is always demanding. The connection between advanced engineering development (6.3 category funds) and immediate Fleet usage brings added complexity and challenge, both technical and organizational. Illustrative examples of affordable engineering solutions to ''retain, revise, replace or retire'' questions are presented within the context of both Fleet realities and budgetary limitations. The discussion covers legacy system support, civil/military considerations and Fleet maintenance issues. It describes the substantial and critical payoffs i

The military services are being moved in the direction of performance-based specifications and standards. They are being steered against dictating ''how to'' produce an item since such action forecloses on the ability to gain access to components or technology that may have a commercial equivalent. Why should the engineering community embrace the new approach? Aside from the obvious weight of it being approved policy, therefore currently mandated, it warrants examination because it is the correct approach at this time when applied to appropriate products. Military specifications and standards are to be displaced then, by acceptable alternative contractor design solutions. Industry bidders will be allowed to propose the particular design details, permitting procurement flexibility by contractually citing only system level or interface requirements, both physical and functional. Hopefully, this can broaden the industrial base and increase competition with reduced costs to follow. Conceptually, the approach appears both performance-sensible and cost-attractive (there are, of course, consequent risks) but how does implementation proceed? Is it possible to pursue the goals envisioned along paths that are not in themselves experimental? Can the American postulate, minimal loss of life and limb to U.S. military people, continue to be honored? Experience and track record elsewhere imply encouraging possibilities in select situations-useful prospects are identified and discussed in practical terms.

This paper sets forth computer systems architecture concepts for the combat system of the 2010–2030 timeframe that satisfy the needs of the next generation of surface combatants. It builds upon the current Aegis computer systems architecture, expanding that architecture while preserving, and adhering to, the Aegis fundamental principle of thorough systems engineering, dedicated to maintaining a well integrated, highly reliable, and easily operable combat system. The implementation of these proposed computer systems concepts in a coherent architecture would support the future battle force capable combat system and allow the expansion necessary to accommodate evolutionary changes in both the threat environment and the technology then available to effectively counter that threat. Changes to the current Aegis computer architecture must be carefully and effectively managed such that the fleet will retain its combat readiness capability at all times. This paper describes a possible transition approach for evolving the current Aegis computer architecture to a general architecture for the future. The proposed computer systems architecture concepts encompass the use of combinations of physically distributed, microprocessor-based computers, collocated with the equipment they support or embedded within the equipment itself. They draw heavily on widely used and available industry standards, including instruction set architectures (ISAs), backplane busses, microprocessors, computer programming languages and development environments, and local area networks (LANs). In this proposal, LANs, based on fiber optics, will provide the interconnection to support system expandability, redundancy, and higher data throughput rates. A system of cross connected LANs will support a high level of combat system integration, spanning the major warfare areas, and will facilitate the coordination and development of a coherent multi-warfare tactical picture supporting the future combatant command st

DOCTRINAL AUTOMATION IN NAVAL combat systems - THE EXPERIENCE AND THE FUTURE

引用

NAVAL ENGINEERS JOURNAL 1987年第3期99卷 74-79页

作者： GERSH, JR The authoris a principal staff engineer at The Johns Hopkins University Applied Physics Laboratory where he supervises the AAW Operations Section of the Combat Direction Group. Since joining JHU/APL in 1980 he has been involved in the specification development and testing of advanced surface combat direction systems specializing in the application of rule-based control mechanisms to command and control problems. In 1985-86 he chaired the Doctrine Working Group of the Naval Sea Systems Command's Combat Direction System Engineering Committee. Mr. Gersh served in the U.S. Navy from 1968 to 1977 as a sonar technician and as a junior officer (engineering and gunnery) aboard Atlantic Fleet frigates and as a member of the U.S. Naval Academy's Electrical Engineering faculty. He was educated at Harvard University and the Massachusetts Institute of Technology receiving S. B. S. M. and E. E. degrees in electrical engineering from the latter. He holds certificates as a commercial pilot and flight instructor and is a member of the U.S. Naval Institute the IEEE Computer Society and the American Association for Artificial Intelligence.

For the last four years the most advanced surface combat direction system (CDS) of the U.S. Navy has employed a limited knowledge-based control mechanism. Implemented in the Aegis Weapon System's command and decision element, this capability is called control by doctrine, and is a foundation for the Ticonderoga class cruisers' exceptional performance. control by doctrine allows CIC personnel to direct that certain CDS functions be performed automatically upon tracks with specified characteristics. In effect, these CDS functions, from identification to engagement, can now be controlled through the specification and activation of general system response rules rather than by individual operator actions. The set of active rules, called doctrine statements, forms a system knowledge-base. The Advanced combat Direction System, Block 1, successor to today's Naval Tactical Data System, will also employ control by doctrine. As part of a larger effort investigating Aegis/ACDS commonality issues, a Doctrine Working Group was chartered to consider, among other things, implications for force-wide interoperability of multiple systems with such rule-based control mechanisms. The working group produced a set of design objectives for doctrine statement standardization across CDSs. Principal features of these objectives are described. The prospect of several such ships operating together in a battle group has raised questions as to the methods by which the actions of ships with those doctrinally-automated systems can best be coordinated. Related questions deal with specific design features for the support of such coordinated action. Work is now being carried out to investigate these questions. combat system automation through doctrine statements is only one kind of rule-based control. Much work in the area of artificial intelligence deals with the use and maintenance of complex systems of rules, usually in non-real-time problem solving applications. Such systems are just now beginning

combat SYSTEM INDUSTRIAL-TESTING - MEASUREMENT OF SUCCESS

引用

NAVAL ENGINEERS JOURNAL 1986年第5期98卷 47-57页

作者： TRESSLER, DL HART, JB Dennis L. Tresseler is currently combat system test team leader for the combat systems test and evaluation branch of the Naval Sea Systems Command (SEA 61 × 11). Mr. Tresseler graduated in 1972 with a degree in mechanical engineering technology. He began his career at Newport News Shipbuilding in 1972 where he was a test director responsible for weapon system installation alignment and testing in CGN-36 thru 40 and CVN-68 and 69. In 1977 he came to the Washington area and worked for various contractors in technical and managerial positions before coming to NA VSEA in 1981. He is a member of the Naval Institute and his paper on “FF-1041 Class Modernization” has been accepted for publication in the Proceedings. J.B. Hart is currently the senior program manager combat systems for VSE Corporation headquartered in Alexandria Virginia. He is the program manager for VSE's master ordnance repair (MOR) team. His previous position was with COMPTEK Research Inc. Virginia Beach as senior combat systems engineer. Mr. Hart earned his BS degree from the University of New York in general engineering. He retired as chief ordnance control warrant officer after 22 years of service in 1982. While on active duty he served in various combat systems capacities since 1968 the most noteworthy of which were as ship's combat systems test officer/fire control officer on USS Belknap (CG-26) bringing her back into commission through major reconstruction and as combat system chief onboard USS Albany (CG-10) assisting in test and delivery of the first NTDS model 4.0 software program as well as numerous control systems updates both software and hardware.

This is an overview of the combat system test and certification (CST&C) program as a subset of the total ship test program (TSTP) for active fleet surface ships. The paper will discuss how the T&C program measures not only the suitability of repairs and modifications done during a ship's combat system industrial availability in a public or private yard period, but also the impact that successful program conduct has on the materiel effectiveness throughout a ship's operational cycle. The CST&C management organization and responsibilities, including NAVSEA's master ordnance repair program as well as combat system code 190's relationship to the CST&C program and the impact of pre- and post-industrial testing requirements on the actual conduct of industrial testing will be addressed.
