| 2026 | Harnessing Textual Semantic Priors for Knowledge Transfer and Refinement in CLIP-Driven Continual LearningabstractContinual learning (CL) aims to equip models with the ability to learn from a stream of tasks without forgetting previous knowledge. With the progress of vision-language models like Contrastive Language-Image Pre-training (CLIP), their promise for CL has attracted increasing attention due to their strong generalizability. However, the potential of rich textual semantic priors in CLIP in addressing the stability–plasticity dilemma remains underexplored. During backbone training, most approaches transfer past knowledge without considering semantic relevance, leading to interference from unrelated tasks that disrupt the balance between stability and plasticity. Besides, while text-based classifiers provide strong generalization, they suffer from limited plasticity due to the inherent modality gap in CLIP. Visual classifiers help bridge this gap, but their prototypes lack rich and precise semantics. To address these challenges, we propose Semantic-Enriched Continual Adaptation (SECA), a unified framework that harnesses the anti-forgetting and structured nature of textual priors to guide semantic-aware knowledge transfer in the backbone and reinforce the semantic structure of the visual classifier. Specifically, a Semantic-Guided Adaptive Knowledge Transfer (SG-AKT) module is proposed to assess new images' relevance to diverse historical visual knowledge via textual cues, and aggregate relevant knowledge in an instance-adaptive manner as distillation signals. Moreover, a Semantic-Enhanced Visual Prototype Refinement (SE-VPR) module is introduced to refine visual prototypes using inter-class semantic relations captured in class-wise textual embeddings. Extensive experiments on multiple benchmarks validate the effectiveness of our approach. De Cheng, Di Xu 0010, Huaijie Wang, Nannan Wang 0001 |

| 2026 | Do Large Language Models Reason About Uncertainty Like Humans? A Benchmark on Hurricane Forecast Visualization ComprehensionabstractUncertainty visualizations, such as hurricane cones and ensemble tracks, are essential for risk communication but are often misinterpreted, leading to harmful decisions. As AI assistants like large language models (LLMs) increasingly support understanding of graphics and decision-making, they offer a promising pathway to enhance the interpretation of complex visualizations and a new opportunity to examine and improve the interpretation of uncertainty. We introduce UnReason, the first benchmark that systematically compares how humans and LLMs reason about hurricane forecast uncertainty visualizations. UnReason spans two escalating phases, seven representative visualization formats, six real hurricane cases, and three agent types (humans, LLMs with context, and LLMs without context), including 880 visualizations and 117,600 structured question–answer pairs under matched evaluation conditions. Phase 1 evaluates reasoning across implicit and explicit uncertainty encodings; Phase 2 examines reasoning under single- versus multi-dimensional uncertainty representations. We thoroughly assess damage estimation, reasoning strategies, and comprehension patterns, revealing that LLMs have a stronger semantic and conceptual understanding of uncertainty, and are less misled by visual variability, but still replicate key human biases during decision-making. Our findings offer insights into aligning LLM behavior with human cognition in uncertainty-rich visual reasoning tasks.

| 2026 | DuGI-MAE: Improving Infrared Mask Autoencoders via Dual-Domain GuidanceabstractInfrared imaging plays a critical role in low-light and adverse weather conditions. However, due to the distinct characteristics of infrared images, existing foundation models such as Masked Autoencoder (MAE) trained on visible data perform suboptimal in infrared image interpretation tasks. To bridge this gap, an infrared foundation model known as InfMAE was developed and pre-trained on large-scale infrared datasets. Despite its effectiveness, InfMAE still faces several limitations, including the omission of informative tokens, insufficient modeling of global associations, and neglect of non-uniform noise. In this paper, we propose a Dual-domain Guided Infrared foundation model based on MAE (DuGI-MAE). First, we design a deterministic masking strategy based on token entropy, preserving only high-entropy tokens for reconstruction to enhance informativeness. Next, we introduce a Dual-Domain Guidance (DDG) module, which simultaneously captures global token relationships and adaptively filters non-uniform background noise commonly present in infrared imagery. To facilitate large-scale pretraining, we construct Inf-590K, a comprehensive infrared image dataset encompassing diverse scenes, various target types, and multiple spatial resolutions. Pretrained on Inf-590K, DuGI-MAE demonstrates strong generalization capabilities across various downstream tasks, including infrared object detection, semantic segmentation, and small target detection. Experimental results validate the superiority of the proposed method over both supervised and self-supervised comparison methods. Yinghui Xing, Xiaoting Su, Shizhou Zhang, Donghao Chu, Di Xu 0010 |

| 2026 | YOLO-IOD: Towards Real Time Incremental Object DetectionabstractCurrent methodologies for incremental object detection (IOD) primarily rely on Faster R-CNN or DETR series detectors; however, these approaches do not accommodate the real-time YOLO detection frameworks. In this paper, we first identify three primary types of knowledge conflicts that contribute to catastrophic forgetting in YOLO-based incremental detectors: foreground-background confusion, parameter interference, and misaligned knowledge distillation. Subsequently, we introduce YOLO-IOD, a real-time Incremental Object Detection (IOD) framework that is constructed upon the pretrained YOLO-World model, facilitating incremental learning via a stage-wise parameter-efficient finetuning process. Specifically, YOLO-IOD encompasses three principal components: 1) Conflict-Aware Pseudo-Label Refinement (CPR), which mitigates the foreground-background confusion by leveraging the confidence levels of pseudo labels and identifying potential objects relevant to future tasks. 2) Importance-based Kernel Selection (IKS), which identifies and updates the pivotal convolution kernels pertinent to the current task during the current learning stage. 3)Cross-Stage Asymmetric Knowledge Distillation (CAKD), which addresses the misaligned knowledge distillation conflict by transmitting the features of the student target detector through the detection heads of both the previous and current teacher detectors, thereby facilitating asymmetric distillation between existing and newly introduced categories. We further introduce LoCo COCO, a more realistic benchmark that eliminates data leakage across stages. Experiments on both conventional and LoCo COCO benchmarks show that YOLO-IOD achieves superior performance with minimal forgetting.

| 2025 | Dual-Granularity Semantic Guided Sparse Routing Diffusion Model for General PansharpeningabstractPansharpening aims at integrating complementary information from panchromatic and multispectral images. Available deep-learning based pansharpening methods typically perform exceptionally with particular satellite datasets. At the same time, it has been observed that these models also exhibit scene dependence, for example, if the majority of the training samples come from the urban scenes, the model’s performance may decline in the river scene. To address the domain gap produced by varying satellite sensors and distinct scenes, we propose a dual-granularity semantic guided sparse routing diffusion model for general pansharpening. By utilizing the large Vision-Language Models (VLMs) in the field of geoscience, e.g, GeoChat, we introduce the dual granularity semantics to generate dynamic sparse routing scores for adaptation of different satellite sensors and scenes. This scene-level and region-level dual-granularity semantic information serves as guidance for dynamically activating specialized experts within the diffusion model. Extensive experiments on WorldView-3, QuickBird, and GaoFen-2 datasets show the effectiveness of our proposed method. Notably, the proposed method outperforms the comparison approaches in adapting to new satellite sensors and scenes. The codes are available at https://github.com/codgodtao/SGDiff.

| 2025 | Revisiting Generative Replay for Class Incremental Object DetectionabstractGenerative replay has gained significant attention in class-incremental learning; however, its application to Class Incremental Object Detection (CIOD) remains limited due to the challenges in generating complex images with precise spatial arrangements. In this study, motivated by the observation that the forgetting of prior knowledge is predominantly present in the classification sub-task as opposed to the localization sub-task, we revisit the generative replay method for class incremental object detection. Our method utilize a standard Stable Diffusion model to generate image-level replay data for all old and new tasks. Accordingly, the old detector and a stage-wise detector are conducted on the synthetic images respectively to determine the bounding box positions through pseudo-labeling. Furthermore, we propose to use a Similarity-based Cross Sampling mechanism to select valuable confusing data between old and new tasks to more effectively mitigate catastrophic forgetting and reduce the false alarm rate for the new task. Finally, all synthetic and real data are integrated for current-stage detector training, where the images generated for previous tasks are highly beneficial in minimizing the forgetting of existing knowledge, while those synthesized for the new task can help bridge the domain gap between real and synthetic images. We conducted extensive experiments on PASCAL VOC 2007 and MS COCO benchmark datasets in multiple settings to showcase the efficacy of our proposed approach, which achieves state-of-the-art results. The code is available at https://github.com/qiangzailv/RGR-IOD. Shizhou Zhang, Xueqiang Lv, Yinghui Xing, Qirui Wu, Di Xu 0010, Yanning Zhang 0001 |

| 2025 | Demystifying Catastrophic Forgetting in Two-Stage Incremental Object DetectorabstractCatastrophic forgetting is a critical chanllenge for incremental object detection (IOD). Most existing methods treat the detector monolithically, relying on instance replay or knowledge distillation without analyzing component-specific forgetting. Through dissection of Faster R-CNN, we reveal a key insight: Catastrophic forgetting is predominantly localized to the RoI Head classifier, while regressors retain robustness across incremental stages. This finding challenges conventional assumptions, motivating us to develop a framework termed NSGP-RePRE. Regional Prototype Replay (RePRE) mitigates classifier forgetting via replay of two types of prototypes: coarse prototypes represent class-wise semantic centers of RoI features, while fine-grained prototypes model intra-class variations. Null Space Gradient Projection (NSGP) is further introduced to eliminate prototype-feature misalignment by updating the feature extractor in directions orthogonal to subspace of old inputs via gradient projection, aligning RePRE with incremental learning dynamics. Our simple yet effective design allows NSGP-RePRE to achieve state-of-the-art performance on the Pascal VOC and MS COCO datasets under various settings. Our work not only advances IOD methodology but also provide pivotal insights for catastrophic forgetting mitigation in IOD. Code will be available soon.

| 2025 | Amplitude-aware Domain Style Replay for Lifelong Person Re-identificationabstractLifelong Person Re-identification (LReID) focuses on continuously adapting to new domains over time while preserving knowledge from previously seen domains, particularly under the domain incremental learning setting. The major challenge of LReID is catastrophic forgetting, typically caused by large domain shifts during training. To address this, we propose a novel Amplitude-aware Domain Style Replay (ADSR) framework, which introduces a Fourier-based Style Transfer (FST) mechanism to generate synthetic data that reflects the style of previously encountered domains. These proxy images help retain prior knowledge without the need to store actual past data. Our method transfers stylistic information-mainly encoded in the amplitude spectrum-from old domains to new ones, creating old-stylized images that preserve the content of new domain data while adopting the visual style of earlier domains. To further boost generalization, we design a Self-Stylization Normalization (SSN) module that adapts the current domain's style distribution, making the model more robust to stylistic variations. Additionally, we introduce a Multi-Granularity Transfer (MGT) module that uses K-Means clustering to extract multiple representative style features from each domain, enabling compact yet comprehensive storage and replay of domain-specific information. Extensive experiments on multiple LReID benchmarks show that ADSR achieves superior performance over existing approaches, effectively reducing forgetting and improving cross-domain generalization.

| 2025 | SUVIS: A Depth- and Motion-Encoded Stereoscopic System for Communicating Forecast UncertaintyabstractEffectively communicating uncertainty in ensemble hurricane forecasts poses a significant multimedia challenge, requiring the integration of spatial, temporal, and perceptual dimensions. We introduce SUVIS, a stereoscopic visualization system that encodes forecast ensembles into an immersive, layered media experience. SUVIS transforms multidimensional ensemble data into animated stereoscopic representations, mapping time to vertical depth, intensity to texture color, and forward speed to motion flow, while semi-transparent glyphs represent evolving impact areas. A progressive sampling strategy ensures spatial clarity across depth layers. Rendered on a glasses-free stereoscopic display, SUVIS frames uncertainty visualization as a media encoding problem, synthesizing motion, depth, and spatial abstraction to align with human perception. A user study with 51 participants demonstrates that SUVIS supports high accuracy in spatial tasks and enables interpretation of dynamic storm attributes. These results highlight the system's potential to advance perceptual uncertainty communication through multimedia representation and immersive visual encoding.

| 2025 | ChatHSI: Reliable LLM-Powered Human-Swarm Interaction FrameworkabstractHuman-swarm interaction (HSI) is critical for scalable control of UAV swarm systems. Traditional interfaces struggle with generalization and user workload, especially in immersive environments. Hence, we present ChatHSI, a framework leveraging large language models (LLMs) for swarm task planning. ChatHSI integrates prompt engineering, action validation, and a human-in-the-loop mechanism to improve planning feasibility and executability. We implement ChatHSI in an immersive simulation to improve users’ spatial and situational awareness. Our method shows improved task efficiency, reduced workload, and higher usability in user studies. Ablation study proves the effectiveness of prompt context and action validation. The results show the feasibility of LLM-driven interaction for immersive swarm control and point toward adaptive, intuitive, and scalable HSI systems.

| 2023 | An Improved Combination of Faster R-CNN and U-Net Network for Accurate Multi-Modality Whole Heart SegmentationabstractDetailed information of substructures of the whole heart is usually vital in the diagnosis of cardiovascular diseases and in 3D modeling of the heart. Deep convolutional neural networks have been demonstrated to achieve state-of-the-art performance in 3D cardiac structures segmentation. However, when dealing with high-resolution 3D data, current methods employing tiling strategies usually degrade segmentation performances due to GPU memory constraints. This work develops a two-stage multi-modality whole heart segmentation strategy, which adopts an improved Combination of Faster R-CNN and 3D U-Net (CFUN+). More specifically, the bounding box of the heart is first detected by Faster R-CNN, and then the original Computed Tomography (CT) and Magnetic Resonance Imaging (MRI) images of the heart aligned with the bounding box are input into 3D U-Net for segmentation. The proposed CFUN+ method redefines the bounding box loss function by replacing the previous Intersection over Union (IoU) loss with Complete Intersection over Union (CIoU) loss. Meanwhile, the integration of the edge loss makes the segmentation results more accurate, and also improves the convergence speed. The proposed method achieves an average Dice score of 91.1% on the Multi-Modality Whole Heart Segmentation (MM-WHS) 2017 challenge CT dataset, which is 5.2% higher than the baseline CFUN model, and achieves state-of-the-art segmentation results. In addition, the segmentation speed of a single heart has been dramatically improved from a few minutes to less than 6 seconds.
