PlaneRAS: Learning Planar Primitives for 3D Plane Recovery
Authors: Fang Zhang; Wenzhao Zheng; Linqing Zhao; Zelan Zhu; Jiwen Lu; Xiuzhuang Zhou
Venue: ICCV 2025 (main)

Abstract: 3D plane recovery from monocular images constitutes a fundamental task in indoor scene understanding. Recent methods formulate this problem as 2D pixel-level segmentation through convolutional networks or query-based architectures, which purely rely on 2D pixel features while neglecting the inherent 3D spatial nature of planar surfaces. To address this limitation, we propose an end-to-end Plane Reconstruction, Aggregation, and Splatting (PlaneRAS) framework that explicitly leverages 3D geometric reasoning combined with online planar primitive reconstruction. Our framework introduces two core components: 1) a reconstruction module utilizing customized planar primitives to compactly represent 3D scene, and 2) a recovery module that aggregates local primitives to derive globally consistent plane instances. The proposed 3D-aware representation enables direct integration of pretrained geometric priors, significantly enhancing performance beyond conventional 2D-centric approaches. Extensive experiments on ScanNet and NYUv2 datasets demonstrate state-of-the-art results across various evaluation metrics, resulting from our explicit 3D geometric modeling and effective fusion of cross-dimensional features.
TARS: Traffic-Aware Radar Scene Flow Estimation
Authors: Jialong Wu; Marco Braun; Dominic Spata; Matthias Rottmann
Venue: ICCV 2025 (main)

Abstract: Scene flow provides crucial motion information for autonomous driving. Recent LiDAR scene flow models utilize the rigid-motion assumption at the instance level, assuming objects are rigid bodies. However, these instance-level methods are not suitable for sparse radar point clouds. In this work, we present a novel Traffic-Aware Radar Scene-Flow (TARS) estimation method, which utilizes motion rigidity at the traffic level. To address the challenges in radar scene flow, we perform object detection and scene flow jointly and boost the latter. We incorporate the feature map from the object detector, trained with detection losses, to make radar scene flow aware of the environment and road users. From this, we construct a Traffic Vector Field (TVF) in the feature space to achieve holistic traffic-level scene understanding in our scene flow branch. When estimating the scene flow, we consider both point-level motion cues from point neighbors and traffic-level consistency of rigid motion within the space. TARS outperforms the state of the art on a proprietary dataset and the View-of-Delft dataset, improving the benchmarks by 23% and 15%, respectively.
Multi-Cache Enhanced Prototype Learning for Test-Time Generalization of Vision-Language Models
Authors: Xinyu Chen; Haotian Zhai; Can Zhang; Xiupeng Shi; Ruirui Li
Venue: ICCV 2025 (main)

Abstract: In zero-shot setting, test-time adaptation adjusts pre-trained models using unlabeled data from the test phase to enhance performance on unknown test distributions. Existing cache-enhanced TTA methods rely on a low-entropy criterion to select samples for prototype construction, assuming intra-class compactness. However, low-entropy samples may be unreliable under distribution shifts, and the resulting prototypes may not ensure compact intra-class distributions. This study identifies a positive correlation between cache-enhanced performance and intra-class compactness. Based on this observation, we propose a Multi-Cache enhanced Prototype-based Test-Time Adaptation (MCP) featuring three caches: an entropy cache for initializing prototype representations with low-entropy samples, an align cache for integrating visual and textual information to achieve compact intra-class distributions, and a negative cache for prediction calibration using high-entropy samples. We further developed MCP++, a framework incorporating cross-modal prototype alignment and residual learning, introducing prototype residual fine-tuning. Comparative and ablation experiments across 15 downstream tasks demonstrate that the proposed method and framework achieve state-of-the-art generalization performance.
MotionFollower: Editing Video Motion via Score-Guided Diffusion

Venue: ICCV 2025 (main)

Abstract: Despite impressive advancements in diffusion-based video editing models in altering video attributes, there has been limited exploration into modifying motion information while preserving the original protagonist's appearance and background. In this paper, we propose MotionFollower, a score-guided diffusion model for video motion editing. To introduce conditional controls to the denoising process, we propose two signal controllers, one for poses and the other for appearances, both consist of convolution blocks without involving heavy attention calculations. Further, we design a score guidance principle based on a two-branch architecture (a reconstruction and an editing branch), significantly enhancing the modeling capability of texture details and complicated backgrounds. Concretely, we enforce several consistency regularizers during the score estimation. The resulting gradients thus inject appropriate guidance to latents, forcing the model to preserve the original background details and protagonists' appearances without interfering with the motion modification. Experiments demonstrate MotionFollower's competitive motion editing ability qualitatively and quantitatively. Compared with MotionEditor, the most advanced motion editing model, MotionFollower delivers superior motion editing performance and exclusively supports large camera movements. To the best of our knowledge, MotionFollower is the first diffusion model to explore score regularization in video editing.
Learning Few-Step Diffusion Models by Trajectory Distribution Matching

Venue: ICCV 2025 (main)

Abstract: Accelerating diffusion model sampling is crucial for efficient AIGC deployment. While diffusion distillation methods -- based on distribution matching and trajectory matching -- reduce sampling to as few as one step, they fall short on complex tasks like text-to-image generation. Few-step generation offers a better balance between speed and quality, but existing approaches face a persistent trade-off: distribution matching lacks flexibility for multi-step sampling, while trajectory matching often yields suboptimal image quality.To bridge this gap, we propose learning few-step diffusion models by Trajectory Distribution Matching (TDM), a unified distillation paradigm that combines the strengths of distribution and trajectory matching. Our method introduces a data-free score distillation objective, aligning the student's trajectory with the teacher's at the distribution level. Further, we develop a sampling-steps-aware objective that decouples learning targets across different steps, enabling more adjustable sampling.This approach supports both deterministic sampling for superior image quality and flexible multi-step adaptation, achieving state-of-the-art performance with remarkable efficiency. Our model, TDM, outperforms existing methods on various backbones, such as SDXL and PixArt-\alpha, delivering superior quality and significantly reduced training costs.In particular, our method distills PixArt-\alpha into a 4-step generator that outperforms its teacher on real user preference at 1024 resolution. This is accomplished with 500 iterations and 2 A800 hours -- a training cost of approximately 1% of the previous state-of-the-art distillation method. In addition, our proposed TDM can be extended to accelerate text-to-video diffusion. Notably, TDM can outperform its teacher model (CogVideoX-2B) by using only 4 NFE on VBench, improving the total score from 80.91 to 81.65.
Unified Multi-Agent Trajectory Modeling with Masked Trajectory Diffusion
Authors: Songru Yang; Zhenwei Shi; Zhengxia Zou
Venue: ICCV 2025 (main)

Abstract: Understanding movements in multi-agent scenarios is a fundamental problem in intelligent systems. Previous research assumes complete and synchronized observations. However, real-world partial observation caused by occlusions leads to inevitable model failure, which demands a unified framework for coexisting trajectory prediction, imputation, and recovery. Unlike previous attempts that handled observed and unobserved behaviors in a coupled manner, we explore a decoupled denoising diffusion modeling paradigm with a unidirectional information valve to separate the interference from uncertain behaviors. Building on this, we proposed a Unified Masked Trajectory Diffusion model (UniMTD) for arbitrary levels of missing observations. We designed a unidirectional attention as a valve unit to control the direction of information flow between the observed and masked areas, gradually refining the missing observations toward a real-world distribution. We construct it into a unidirectional MoE structure to handle varying proportions of missing observations. A Cached Diffusion model is further designed to improve generation quality while reducing computation and time overhead. Our method has achieved a great leap across human motions and vehicle traffic. UniMTD efficiently achieves 65% improvement in minADE20 and reaches SOTA with advantages of 98%, 50%, 73%, and 29% across 4 fidelity metrics on out-of-boundary, velocity, and trajectory length. Our code will be released here.
Certifiably Optimal Anisotropic Rotation Averaging
Authors: Carl Olsson; Yaroslava Lochman; Johan Malmport; Christopher Zach
Venue: ICCV 2025 (main)

Abstract: Rotation averaging is a key subproblem in applications of computer vision and robotics. Many methods for solving this problem exist, and there are also several theoretical results analyzing difficulty and optimality. However, one aspect that most of these have in common is a focus on the isotropic setting, where the intrinsic uncertainties in the measurements are not fully incorporated into the resulting optimization task. Recent empirical results suggest that moving to an anisotropic framework, where these uncertainties are explicitly included, can result in an improvement of solution quality. However, global optimization for rotation averaging has remained a challenge in this scenario.In this paper we show how anisotropic costs can be incorporated in certifiably optimal rotation averaging. We also demonstrate how existing solvers, designed for isotropic situations, fail in the anisotropic setting. Finally, we propose a stronger relaxation and show empirically that it is able to recover global optima in all tested datasets and leads to a more accurate reconstruction in all but one of the scenes.
TeRA: Rethinking Text-guided Realistic 3D Avatar Generation

Venue: ICCV 2025 (main)

Abstract: Efficient 3D avatar creation is a significant demand in the metaverse, film/game, AR/VR, etc. In this paper, we rethink text-to-avatar generative models by proposing TeRA, a more efficient and effective framework than the previous SDS-based models and general large 3D generative models. Our approach employs a two-stage training strategy for learning a native 3D avatar generative model. Initially, we distill a decoder to derive a structured latent space from a large human reconstruction model. Subsequently, a text-controlled latent diffusion model is trained to generate photorealistic 3D human avatars within this latent space. TeRA enhances the model performance by eliminating slow iterative optimization and enables text-based partial customization through a structured 3D human representation. Experiments have proven our approach's superiority over previous text-to-avatar generative models in subjective and objective evaluation.
Understanding Flatness in Generative Models: Its Role and Benefits
Authors: Taehwan Lee; Kyeongkook Seo; Jaejun Yoo; Sung Whan Yoon
Venue: ICCV 2025 (main)

Abstract: Flat minima, known to enhance generalization and robustness in supervised learning, remain largely unexplored in generative models. In this work, we systematically investigate the role of loss surface flatness in generative models, both theoretically and empirically, with a particular focus on diffusion models. We establish a theoretical claim that flatter minima improve robustness against perturbations in target prior distributions, leading to benefits such as reduced exposure bias---where errors in noise estimation accumulate over iterations---and significantly improved resilience to model quantization, preserving generative performance even under strong quantization constraints. We further observe that Sharpness-Aware Minimization (SAM), which explicitly controls the degree of flatness, effectively enhances flatness in diffusion models even surpassing the indirectly promoting flatness methods---Input Perturbation (IP) which enforces the Lipschitz condition, ensembling-based approach like Stochastic Weight Averaging (SWA) and Exponential Moving Average (EMA)---are less effective. Through extensive experiments on CIFAR-10, LSUN Tower, and FFHQ, we demonstrate that flat minima in diffusion models indeed improve not only generative performance but also robustness.
UniGlyph: Unified Segmentation-Conditioned Diffusion for Precise Visual Text Synthesis

Venue: ICCV 2025 (main)

Abstract: Text-to-image generation has transformed content creation, yet precise visual text rendering remains challenging for generative models due to blurred glyphs, semantic inconsistencies, and limited style controllability. Current methods typically employ pre-rendered glyph images as conditional inputs, but their inability to preserve original font styles and color information forces reliance on multi-branch architectures to compensate for missing details. This leads to increased model complexity, higher computational costs, and reduced reusability.To address these limitations, we propose a segmentation-guided framework that leverages pixel-level visual text segmentation masks--complete representations preserving glyph shapes, colors, and spatial details--as unified conditional inputs. Our approach integrates two key innovations: (1) a fine-tuned bilingual segmentation model for extracting precise text masks from source images, and (2) a streamlined diffusion model enhanced with adaptive glyph condition and glyph region loss to ensure semantic and stylistic fidelity. On the AnyText-benchmark, our method achieves a sentence accuracy (Sen.Acc) of 0.8267 and a Normalized Edit Distance (NED) of 0.8976 for Chinese text generation, while the English test set delivers even stronger performance with 0.9018 Sen.Acc and 0.9582 NED, surpassing prior methods by substantial margins. To address broader evaluation needs, we introduce two novel benchmarks: GlyphMM-benchmark (for holistic glyph consistency assessment) and MiniText-benchmark (targeting small-scale glyph fidelity analysis). Experimental results demonstrate our method's dominance across these new benchmarks: 16% Sen.Acc improvement on the Chinese subset of GlyphMM-benchmark and 50% gain on its English counterpart. Notably, our approach achieves over a 100% Sen.Acc boost on the challenging MiniText test set designed for localized text regions. This breakthrough validates our architecture's dual strengths: simplified deployment-ready design and superior generalization for cross-lingual text rendering tasks.
DCHM: Depth-Consistent Human Modeling for Multiview Detection
Authors: Jiahao Ma; Tianyu Wang; Miaomiao Liu; David Ahmedt-Aristizabal; Chuong Nguyen
Venue: ICCV 2025 (main)

Abstract: Multiview pedestrian detection typically involves two stages: human modeling and pedestrian localization. Human modeling represents pedestrians in 3D space by fusing multiview information, making its quality crucial for detection accuracy. However, existing methods often introduce noise and have low precision. While some approaches reduce noise by fitting on costly multiview 3D annotations, they often struggle to generalize across diverse scenes. To eliminate reliance on human-labeled annotations and accurately model humans, we propose Depth-Consistency Human Modeling (DCHM), a framework designed for consistent depth estimation and multiview fusion in global coordinates. Specifically, our proposed pipeline iteratively achieves multiview depth consistency in sparse-view, large-scaled, and crowded scenarios, producing precise point clouds for pedestrian localization. Extensive experiments demonstrate that our method significantly reduces noise during human modeling, outperforming previous state-of-the-art baselines. Additionally, to the best of our knowledge, we are the first to reconstruct pedestrians and perform multiview segmentation in such a challenging setting.

Venue: ICCV 2025 (main)

Abstract: Person re-identification (Re-ID) is a crucial task in computer vision, aiming to recognize individuals across non-overlapping camera views. While recent advanced vision-language models (VLMs) excel in logical reasoning and multi-task generalization, their applications in Re-ID tasks remain limited. They either struggle to perform accurate matching based on identity-relevant features or assist image-dominated branches as auxiliary semantics. In this paper, we propose a novel framework ChatReID, that shifts the focus towards a text-side-dominated retrieval paradigm, enabling flexible and interactive re-identification. To integrate the reasoning abilities of language models into Re-ID pipelines, We first present a large-scale instruction dataset, which contains more than 8 million prompts to promote the model fine-tuning. Next. we introduce a hierarchical progressive tuning strategy, which endows Re-ID ability through three stages of tuning, i.e., from person attribute understanding to fine-grained image retrieval and to multi-modal task reasoning.Extensive experiments across ten popular benchmarks demonstrate that ChatReID outperforms existing methods, achieving state-of-the-art performance in all Re-ID tasks. More experiments demonstrate that ChatReID not only has the ability to recognize fine-grained details but also to integrate them into a coherent reasoning process.
TAViS: Text-bridged Audio-Visual Segmentation with Foundation Models
Authors: Ziyang Luo; Nian Liu; Xuguang Yang; Salman Khan; Rao Muhammad Anwer; Hisham Cholakkal; Fahad Shahbaz Khan; Junwei Han
Venue: ICCV 2025 (main)

Abstract: Audio-Visual Segmentation (AVS) faces a fundamental challenge of effectively aligning audio and visual modalities. While recent approaches leverage foundation models to address data scarcity, they often rely on single-modality knowledge or combine foundation models in an off-the-shelf manner, failing to address the cross-modal alignment challenge. In this paper, we present TAViS, a novel framework that couples the knowledge of multimodal foundation models (ImageBind) for cross-modal alignment and a segmentation foundation model (SAM2) for precise segmentation. However, effectively combining these models poses two key challenges: the difficulty in transferring the knowledge between SAM2 and ImageBind due to their different feature spaces, and the insufficiency of using only segmentation loss for supervision. To address these challenges, we introduce a text-bridged design with two key components: (1) a text-bridged hybrid prompting mechanism where pseudo text provides class prototype information while retaining modality-specific details from both audio and visual inputs, and (2) an alignment supervision strategy that leverages text as a bridge to align shared semantic concepts within audio-visual modalities. Our approach achieves superior performance on single-source, multi-source, semantic datasets, and excels in zero-shot settings.

Abstract: End-to-end (E2E) autonomous driving methods still struggle to make correct decisions in interactive closed-loop evaluation due to limited causal reasoning capability. Current methods attempt to leverage the powerful understanding and reasoning abilities of Vision-Language Models (VLMs) to resolve this dilemma. However, the problem is still open that few VLMs for E2E methods perform well in the closed-loop evaluation due to the gap between the semantic reasoning space and the purely numerical trajectory output in the action space. To tackle this issue, we propose ORION, a holistic E2E autonomous driving framework by vision-language instructed action generation.ORION uniquely combines a QT-Former to aggregate long-term history context, a Large Language Model (LLM) for driving scenario reasoning, and a generative planner for precision trajectory prediction. ORION further aligns the reasoning space and the action space to implement a unified E2E optimization for both visual question-answering (VQA) and planning tasks. Our method achieves an impressive closed-loop performance of 77.47 Driving Score (DS) and 54.62% Success Rate (SR) on the challenge Bench2Drive datasets, which outperforms state-of-the-art (SOTA) methods by a large margin of 14.28 DS and 28.08% SR.
GeoExplorer: Active Geo-localization with Curiosity-Driven Exploration
Authors: Li Mi; Manon Béchaz; Zeming Chen; Antoine Bosselut; Devis Tuia
Venue: ICCV 2025 (main)

Abstract: Active Geo-localization (AGL) is the task of localizing a goal, represented in various modalities (e.g., aerial images, ground-level images, or text), within a predefined search area. Current methods approach AGL as a goal-reaching reinforcement learning (RL) problem with a distance-based reward. They localize the goal by implicitly learning to minimize the relative distance from it. However, when distance estimation becomes challenging or when encountering unseen targets and environments, the agent exhibits reduced robustness and generalization ability due to the less reliable exploration strategy learned during training. In this paper, we propose GeoExplorer, an AGL agent that incorporates curiosity-driven exploration through intrinsic rewards. Unlike distance-based rewards, our curiosity-driven reward is goal-agnostic, enabling robust, diverse, and contextually relevant exploration based on effective environment modeling. These capabilities have been proven through extensive experiments across four AGL benchmarks, demonstrating the effectiveness and generalization ability of GeoExplorer in diverse settings, particularly in localizing unfamiliar targets and environments.
