This paper aims to build an efficient multi-dimensional visualization platform for GIS landscape data. Through this system, large-scale, multi-type landscape data in the geographic information system can be automatically processed and displayed in multiple dimensions. In the design, this paper adopts an optimized data processing algorithm to ensure the efficiency of data extraction, conversion and integration. Then, multi-dimensional visualization views of different landscape features are automatically generated to support accurate analysis and display of multiple dimensions such as geography, ecology, and climate. The model simulation part is based on a large amount of measured data, and multiple rounds of tests and evaluations have been carried out. The results show that the system is superior to traditional display systems in data display accuracy, real-time performance, and response speed, especially in the fusion display of multi-dimensional data. Data analysis shows that the system can quickly identify and dynamically display different geographical landscape features, providing an effective tool for landscape analysis in geographic information systems. © 2025 ieee.

Story visualization is the transformation of narrative elements into image sequences. While existing research has primarily focused on visual contextual coherence, the deeper narrative essence of stories often remains overlooked. This limitation hinders the practical application of these approaches, as generated images frequently fail to capture the intended meaning and nuances of the narrative fully. To address these challenges, we propose VisAgent, a training-free multi-agent framework designed to comprehend and visualize pivotal scenes within a given story. By considering story distillation, semantic consistency, and contextual coherence, VisAgent employs an agentic workflow. In this workflow, multiple specialized agents collaborate to: (i) refine layered prompts based on the narrative structure and (ii) seamlessly integrate generated elements, including refined prompts, scene elements, and subject placement, into the final image. The empirically validated effectiveness confirms the framework's suitability for practical story visualization applications. © 2025 ieee.

This article proposes a multi-level 3D visualization monitoring technology based on digital twins. Through digital twin technology, we need to simulate laboratory environments, monitor and analyze various parameters in real time. The modeling technology of digital twins can be used for health monitoring and fault prediction of laboratory equipment, thereby reducing equipment damage and downtime, and improving the stability and reliability of laboratory operation. Multi level 3D visualization technology allows users to simultaneously view the global layout and detailed information of the laboratory, providing a more comprehensive monitoring perspective and helping to detect and solve problems in a timely manner. The optimized human-computer interaction technology enables monitoring personnel to interact more naturally with the monitoring system, improving work efficiency. © 2025 ieee.

This paper proposes a design for a visualization system for underwater multi-target tracking based on the Gaussian Mixture Probability Hypothesis Density (GMPHD) filter using Unity 3D engine. Traditional analysis methods for underwater tracking algorithms rely primarily on two-dimensional graphs and numerical data, making it challenging to intuitively understand the complex behavior of tracking systems in three-dimensional underwater environments. Our proposed system design provides a framework for 3D visualization of target movements, sonar sensor detection areas, and filter estimation results, along with an interactive interface for parameter adjustment. The proposed architecture consists of four main components: simulation core, visualization module, environment simulation, and user interface, which would enable researchers to analyze algorithm performance under various scenarios effectively. Through real-time visualization and parameter adjustment capabilities, the system is designed to offer immediate feedback on how different parameters affect tracking performance. This architectural approach aims to provide researchers with a more intuitive understanding of the GMPHD filter's operation and facilitate the optimization of tracking algorithms for underwater environments. The proposed system design demonstrates the potential of 3D visualization tools in advancing underwater multi-target tracking research and algorithm development. © 2025 ieee.

Emotional information in narrative texts is an important resource for deepening text interpretation and promoting literature utilization, but there is still a lack of dedicated information organization schemes. Based on the systematic analysisof related theories, this study constructed the narrative text emotion ontology (NTEO), which contains three core components of event, appraisal, and emotion, as well as three related components of emotion category, emotion expression, and action tendency, for structuring and organizing the emotion information. Meanwhile, six relations of temporal, cause, circumstance, regulation, change, and trigger were summarized for embedding emotional units into narrative sequences. Furthermore, taking Tsen Shui-fang s Diary, an archive related to the Nanjing Massacre in China, as an example, we explored the innovative applications of fine-grained emotion classification, fine-grained emotion visualization, and emotion attribution analysis supported by this emotion ontology . © 2024 Copyright held by the owner/author(s).

Text-to-visualization (Text2Vis) aims to democratize data insights for non-expert users by transforming natural language query (NLQ) into visualization specification (VS). In view of the high dependence of rule-based methods on predefined VS templates and poor NLQ understanding ability of small data-driven methods, recent works resort to leveraging pre-trained LLMs to perform NLQ-understanding and VS-generating in Text2Vis tasks via prompt-guided in-context learning. However, existing LLM-based methods still fall short of satisfactory end-to-end Text2Vis performances primarily owing to the limited ability of pre-trained LLMs in directly retrieving and operating NLQ-intended tabular data. Inspired by the SQL generating ability born with latest LLMs, this paper proposes the idea of harnessing LLMs for SQL-driven visualization data retrieval and operation. Nonetheless, there remains a nonneglectable gap between data visualization queries in Text2Vis tasks and SQL retrieving queries in LLM corpus. To fill the gap, this paper proposes a visualization Query to SQL (VisQ2SQL) framework to obtain NLQ-intended data, primarily by fine-tuning LLMs through preference learning data-retrieval SQLs induced from VS and those generated by LLMs. We conduct extensive experiments to demonstrate the superiority of VisQ2SQL over SOTA methods, and various ablation studies to verify the efficacy of VisQ2SQL. © 2025 ieee.

Planning land use changes requires input from experts across several domains with diverse expertise. Currently available tools were not designed for analysing the required ecosystem services before and after land use changes, or for analysing tradeoffs. Our study is motivated by the need for better tools designed for expert analysts and location knowledgable stakeholders to analyse data relating to land use planning, such as ecosystem services data. The effectiveness of an immersive VR visualization system (Immersive ESS Visualizer) for analysing and visualizing ecosystem services data, is evaluated and compared to existing methods of analysis, paper maps and a 2D screen. Although VR presented some difficulties, the benefits of spatially arranging maps, inspecting fine details, navigation by zooming, and inspection of hillshades provided sufficient advantages to make VR an effective tool for ecosystem services analysis. Participants using Immersive ESS Visualizer arranged handheld maps into 3D layouts, which would not be possible with paper or on the 2D screen. Our research demonstrates that geospatial analysis can be supported by comparative visualization in VR. © 2025 ieee.

STDatav2: Accessing Efficient Black-Box Stealing for Adversarial Attacks

On account of the extreme settings, stealing the black-box model without its training data is difficult in practice. On this topic, along the lines of data diversity, this paper substantially makes the following improvements based on our conference version (dubbed STDatav1, short for Surrogate Training Data). First, to mitigate the undesirable impacts of the potential mode collapse while training the generator, we propose the joint-data optimization scheme, which utilizes both the synthesized data and the proxy data to optimize the surrogate model. Second, we propose the self-conditional data synthesis framework, an interesting effort that builds the pseudo-class mapping framework via grouping class information extraction to hold the class-specific constraints while holding the diversity. Within this new framework, we inherit and integrate the class-specific constraints of STDatav1 and design a dual cross-entropy loss to fit this new framework. Finally, to facilitate comprehensive evaluations, we perform experiments on four commonly adopted datasets, and a total of eight kinds of models are employed. These assessments witness the considerable performance gains compared to our early work and demonstrate the competitive ability and promising potential of our approach.

With the increasing requirements for power supply systems and the continuous improvement of emergency rescue command center system construction, the requirements for early warning emergency systems are constantly increasing. Improve strategic planning, decision-making, and operational command capabilities by using charts, maps, and other visualization tools. Use map tools to provide the emergency command center with comprehensive on-site intelligence, quickly analyze terrain, disaster conditions, and the location of available resources, and conduct combat planning and on-site deployment. Based on the Geographic information System (GIS) and related technologies, data such as resource location and target information are visualized to optimize emergency resource scheduling and combat decisions. The location, movement trajectory and working status of combat units and command nodes are displayed through charts and maps, the visualization of command links and information exchange is established, and the efficiency of combat command is improved. The expansion of map combat capabilities combines advanced information technology with strategic needs, and continuously explores and innovates new methods and tools to improve command decision-making efficiency, optimize combat effectiveness and ensure combat safety. © 2025 SPIE.

Narrow Band Imaging (NBI) is an optical medical imaging technique that utilizes narrow band light to enhance the visualization of mucosa and tissues. NBI has been used to enhance traditional white light endoscopic imaging. A key feature of NBI is its ability to provide high-contrast images of blood vessels in tissues, especially compared to white light. For instance, in gastrointestinal cancer detection, specific narrow-band light such as green light, which is strongly absorbed by hemoglobin in the blood, is used to improve the visualization of blood vessels, aiding physicians in more precise diagnosis and evaluation. NBI can achieve multi-spectral imaging by using various colored lights for illumination or optical filters in white light endoscopes. In this study, we have developed a low-cost NBI multi-spectral system. The NBI system is built with multi-color LEDs into a handheld probe. The system was evaluated on oral mucosa and pigmented mole, demonstrating its promising potential in identifying and classifying pathological changes in epithelial tissues. © 2025 SPIE.
