Continual Adaptation: Environment-Conditional Parameter Generation for Object Detection in Dynamic Scenarios
Authors: Deng Li; Aming Wu; Yang Li; Yaowei Wang; Yahong Han
Venue: ICCV 2025 (main)

Abstract: In practice, environments constantly change over time and space, posing significant challenges for object detectors trained based on a closed-set assumption, i.e., training and test data share the same distribution. To this end, continual test-time adaptation has attracted much attention, aiming to improve detectors' generalization by fine-tuning a few specific parameters, e.g., BatchNorm layers. However, based on a small number of test images, fine-tuning certain parameters may affect the representation ability of other fixed parameters, leading to performance degradation. Instead, we explore a new mechanism, i.e., converting the fine-tuning process to a specific-parameter generation. Particularly, we first design a dual-path LoRA-based domain-aware adapter that disentangles features into domain-invariant and domain-specific components, enabling efficient adaptation. Additionally, a conditional diffusion-based parameter generation mechanism is presented to synthesize the adapter's parameters based on the current environment, preventing the optimization from getting stuck in local optima. Finally, we propose a class-centered optimal transport alignment method to mitigate catastrophic forgetting. Extensive experiments conducted on various continuous domain adaptive object detection tasks demonstrate the effectiveness. Meanwhile, visualization results show that the representation extracted by the generated parameters can capture more object-related information and strengthen the generalization ability.
CATP-LLM: Empowering Large Language Models for Cost-Aware Tool Planning

Venue: ICCV 2025 (main)

Abstract: Utilizing large language models (LLMs) for tool planning has emerged as a promising avenue for developing general AI systems, where LLMs automatically schedule external tools (e.g., vision models) to tackle complex tasks based on task descriptions. To push this paradigm toward practical applications, it is crucial for LLMs to consider tool execution costs (e.g., execution time) for tool planning. Unfortunately, prior studies overlook the tool execution costs, leading to the generation of expensive plans whose costs outweigh their benefits in terms of task performance. To fill this gap, we propose the Cost-Aware Tool Planning with LLMs (CATP-LLM) framework, which for the first time provides a coherent design to empower LLMs for cost-aware tool planning. Specifically, To facilitate efficient concurrent tool execution and cost reduction, we design a tool planning language to enhance the LLM for creating multi-branch non-sequential plans. Moreover, we propose a cost-aware offline reinforcement learning algorithm to fine-tune the LLM to optimize the performance-cost trade-off in tool planning. In the lack of public cost-related datasets, we further present OpenCATP, the first dataset for cost-aware planning, which comprises 11,100 evaluation samples from diverse tasks. Extensive experiments show that CATP-LLM outperforms GPT-4 even when using Llama2-7B as its backbone, with the average plan quality improvement of 1.5%-93.9%.

MoMaps: Semantics-Aware Scene Motion Generation with Motion Maps
Authors: Jiahui Lei; Kyle Genova; George Kopanas; Noah Snavely; Leonidas Guibas
Venue: ICCV 2025 (main)

Abstract: This paper addresses the challenge of learning semantically and functionally meaningful 3D motion priors from real-world videos, in order to enable prediction of future 3D scene motion from a single input image. We propose a novel pixel-aligned Motion Map (MoMap) representation for 3D scene motion, which can be generated from existing generative image models to facilitate efficient and effective motion prediction. To learn meaningful distributions over motion, we create a large-scale database of MoMaps from over 50,000 real videos and train a diffusion model on these representations. Our motion generation not only synthesizes trajectories in 3D but also suggests a new pipeline for 2D video synthesis: first generate a MoMap, then warp an image accordingly and complete the warped point-based renderings. Experimental results demonstrate that our approach generates plausible and semantically consistent 3D scene motion.
WarpHE4D: Dense 4D Head Map toward Full Head Reconstruction
Authors: Jongseob Yun; Yong-Hoon Kwon; Min-Gyu Park; Ju-Mi Kang; Min-Ho Lee; Inho Chang; Ju Hong Yoon; Kuk-Jin Yoon
Venue: ICCV 2025 (main)

Abstract: We address the 3D head reconstruction problem and the facial correspondence search problem in a unified framework, named as WarpHE4D. The underlying idea is to establish correspondences between the facial image and the fixed UV texture map by exploiting powerful self-supervised visual representations, i.e., DINOv2. In other words, we predict UV coordinates for each pixel that maps the pixel to a point in the UV map. At the same time, we predict the nose-centered depth map leveraged by the facial correspondences. Note that our framework does not require fitting a template model, \text e.g.,  3DMM, to the image, which directly regresses 4D vectors for each pixel. The experimental results show that our approach not only improves the accuracy of head geometry but also significantly improves the robustness under pose or viewpoint variations, particularly when the head is rotated more than 90 degrees. We believe our method can be a groundwork for photorealistic head avatar generation, even in uncalibrated camera settings.
Perceive, Understand and Restore: Real-World Image Super-Resolution with Autoregressive Multimodal Generative Models
Authors: Hongyang Wei; Shuaizheng Liu; Chun Yuan; Lei Zhang
Venue: ICCV 2025 (main)

Abstract: By leveraging the generative priors from pre-trained text-to-image diffusion models, significant progress has been made in real-world image super-resolution (Real-ISR). However, these methods tend to generate inaccurate and unnatural reconstructions in complex and/or heavily degraded scenes, primarily due to their limited perception and understanding capability of the input low-quality image. To address these limitations, we propose, for the first time to our knowledge, to adapt the pre-trained autoregressive multimodal model such as Lumina-mGPT into a robust Real-ISR model, namely PURE, which Perceives and Understands the input low-quality image, then REstores its high-quality counterpart. Specifically, we implement instruction tuning on Lumina-mGPT to perceive degradation levels and inter-token dependencies, understand content via semantic description generation, and ultimately restore the image by generating high-quality image tokens autoregressively with the collected information. In addition, we reveal that the image token entropy reflects the image structure and present a entropy-based Top-k sampling strategy to optimize the local structure of the image during inference. Experimental results demonstrate that PURE preserves image content while generating realistic details, especially in complex scenes with multiple objects, showcasing the potential of autoregressive multimodal generative models for robust Real-ISR. The model and code are available at https://github.com/nonwhy/PURE.
TRKT: Weakly Supervised Dynamic Scene Graph Generation with Temporal-enhanced Relation-aware Knowledge Transferring
Authors: Zhu Xu; Ting Lei; Zhimin Li; Guan Wang; Qingchao Chen; Yuxin Peng; Yang Liu
Venue: ICCV 2025 (main)

Abstract: Dynamic Scene Graph Generation (DSGG) aims to create a scene graph for each video frame by detecting objects and predicting their relationships. Weakly Supervised DSGG (WS-DSGG) reduces annotation workload by using an un- localized scene graph from a single frame per video for training. Existing WS-DSGG methods depend on an off-the- shelf external object detector to generate pseudo labels for subsequent DSGG training. However, detectors trained on static, object-centric images struggle in dynamic, relation- aware scenarios required for DSGG, leading to inaccurate localization and low-confidence proposals. To address the challenges posed by external object detectors in WS-DSGG, we propose a Temporal-enhanced Relation-aware Knowl- edge Transferring (TRKT) method, which leverages knowl- edge to enhance detection in relation-aware dynamic sce- narios. TRKT is built on two key components: (1) Relation-aware knowledge mining: we first employ object and re- lation class decoders that generate category-specific atten- tion maps to highlight both object regions and interactive areas. Then we propose an Inter-frame Attention Augmen- tation strategy that exploits optical flow for neighboring frames to enhance the attention maps, making them motion- aware and robust to motion blur. This step yields relation- and motion-aware knowledge mining for WS-DSGG. (2) we introduce a Dual-stream Fusion Module that integrates category-specific attention maps into external detections to refine object localization and boost confidence scores for object proposals. Extensive experiments demonstrate that TRKT achieves state-of-the-art performance on Ac- tion Genome dataset. Our code is avaliable at https: //github.com/XZPKU/TRKT.git.
Progressive Distribution Bridging: Unsupervised Adaptation for Large-scale Pre-trained Models via Adaptive Auxiliary Data
Authors: Weinan He; Yixin Zhang; Zilei Wang
Venue: ICCV 2025 (main)

Abstract: Large-scale pre-trained Vision-Language Models (VLMs) like CLIP have demonstrated promising zero-shot transfer capabilities to downstream tasks. However, their performance deteriorates when facing significant domain shifts. In this paper, we focus on cost-effective adaptation of large-scale pre-trained VLMs to unlabeled target domains. In this context, two prevalent paradigms show inherent limitations: Unsupervised Fine-Tuning (UFT) struggles with poor initial model performance, while Unsupervised Domain Adaptation (UDA) may suffer from adverse effects of inappropriate auxiliary source domain. To alleviate these limitations, we propose to adaptively construct more suitable auxiliary data from large-scale image-text pairs to facilitate unsupervised adaptation without any human annotations. Specifically, we introduce Progressive Distribution Bridging (PDB), which decomposes the challenging adaptation task into multiple simple steps through the construction of auxiliary data. To obtain such data, we design an efficient and controllable retrieval algorithm incorporating cascaded semantic filters and style controller to regulate the semantic category and domain style of retrieved data, respectively. Experimental results across 11 different domains from three standard UDA benchmarks demonstrate the effectiveness of our auxiliary data. Notably, on Office-Home, our method outperforms state-of-the-art UDA methods that rely on labeled source domains. The proposed method offers a more universal and cost-effective solution for adapting VLMs to unlabeled downstream tasks.
Griffon v2: Advancing Multimodal Perception with High-Resolution Scaling and Visual-Language Co-Referring
Authors: Yufei Zhan; Shurong Zheng; Yousong Zhu; Hongyin Zhao; Fan Yang; Ming Tang; Jinqiao Wang
Venue: ICCV 2025 (main)

Abstract: Large Vision Language Models have achieved fine-grained object perception, but the limitation of image resolution remains a significant obstacle to surpassing the performance of task-specific experts in complex and dense scenarios. Such limitation further restricts the model's potential to achieve nuanced visual and language referring in domains such as GUI Agents, counting, etc. To address this issue, we introduce a unified high-resolution generalist model, Griffon v2, enabling flexible object referring with visual and textual prompts. To efficiently scale up image resolution, we design a simple and lightweight down-sampling projector to overcome the input tokens constraint in Large Language Models. This design inherently preserves the complete contexts and fine details and significantly improves multimodal perception ability, especially for small objects. Building upon this, we further equip the model with visual-language co-referring capabilities through a plug-and-play visual tokenizer. It enables user-friendly interaction with flexible target images, free-form texts, and even coordinates. Experiments demonstrate that Griffon v2 can localize objects of interest with visual and textual referring, achieve state-of-the-art performance on REC and phrase grounding, and outperform expert models in object detection, object counting, and REG.

TARO: Timestep-Adaptive Representation Alignment with Onset-Aware Conditioning for Synchronized Video-to-Audio Synthesis
Authors: Tri Ton; Ji Woo Hong; Chang D. Yoo
Venue: ICCV 2025 (main)

Abstract: This paper introduces Timestep-Adaptive Representation Alignment with Onset-Aware Conditioning (TARO), a novel framework for high-fidelity and temporally coherent video-to-audio synthesis. Built upon flow-based transformers, which offer stable training and continuous transformations for enhanced synchronization and audio quality, TARO introduces two key innovations: (1) Timestep-Adaptive Representation Alignment (TRA), which dynamically aligns latent representations by adjusting alignment strength based on the noise schedule, ensuring smooth evolution and improved fidelity, and (2) Onset-Aware Conditioning (OAC), which integrates onset cues that serve as sharp event-driven markers of audio-relevant visual moments to enhance synchronization with dynamic visual events. Extensive experiments on the VGGSound and Landscape datasets demonstrate that TARO outperforms prior methods, achieving relatively 53% lower Frechet Distance (FD), 29% lower Frechet Audio Distance (FAD), and a 97.19% Alignment Accuracy, highlighting its superior audio quality and synchronization precision.

Venue: ICCV 2025 (main)

Abstract: With the rapid advancement of Visual Place Recognition (VPR) systems, their unauthorized use on social media images enables monitoring of individuals' daily movements, posing serious privacy risks. However, privacy protection for addressing these risks in VPR systems remains an underexplored area. While adversarial perturbations have been widely explored for visual privacy protection, existing methods still fail to simultaneously satisfy the black-box constraint, imperceptibility, and real-time performance required in realistic VPR privacy protection scenarios. In this paper, we present the first look at privacy protection in VPR systems and introduce VPR-Cloak, an efficient privacy-preserving network. We introduce a saliency-aware prior to identify decisive regions for place recognition and propose Saliency-Aware Prior Guided Perturbation Optimization (SAP-PO) to selectively optimize perturbation generation in these areas. To enhance imperceptibility, we further optimize perturbations in the frequency domain, meticulously refining high-frequency components of perturbations while preserving low-frequency structures essential for human perception. Extensive experiments verify that our method outperforms existing SOTA methods. Additionally, our method achieves a 15x speedup in runtime compared to SOTA methods. We also validate on Google and Microsoft Bing, demonstrating the practical applicability in real-world scenarios. The code is released at https://github.com/Dilemma-CMZ/VPR-Cloak.
SDFormer: Vision-based 3D Semantic Scene Completion via SAM-assisted Dual-channel Voxel Transformer
Authors: Yujie Xue; Huilong Pi; Jiapeng Zhang; Yunchuan Qin; Zhuo Tang; Kenli Li; Ruihui Li
Venue: ICCV 2025 (main)

Abstract: Vision-based semantic scene completion (SSC) is able to predict complex scene information from limited 2D images, which has attracted widespread attention. Currently, SSC methods typically construct unified voxel features containing both geometry and semantics, which lead to different depth positions in occluded regions sharing the same 2D semantic information, resulting in ambiguous semantic segmentation. To address this problem, we propose SDFormer, a novel SAM-assisted Dual-channel Voxel Transformer framework for SSC. We uncouple the task based on its multi-objective nature and construct two parallel sub-networks: a semantic constructor (SC) and a geometric refiner (GR). The SC utilizes the Segment Anything Model (SAM) to construct dense semantic voxel features from reliable visible semantic information in the image. The GR accurately predicts depth positions and then further adjusts the semantic output by SAM. Additionally, we design a Semantic Calibration Affinity to enhance semantic-aware transformations in SC. Within the GR, Shape Segments Interactive and Learnable mask generation module to emphasize the spatial location of semantics to obtain fine-grained voxel information. Extensive qualitative and quantitative results on the SemanticKITTI and SSCBench-KITTI-360 datasets show that our method outperforms state-of-the-art approaches.
ModSkill: Physical Character Skill Modularization
Authors: Yiming Huang; Zhiyang Dou; Lingjie Liu
Venue: ICCV 2025 (main)

Abstract: Human motion is highly diverse and dynamic, posing challenges for imitation learning algorithms that aim to generalize motor skills for controlling simulated characters. Prior methods typically rely on a universal full-body controller for tracking reference motion (tracking-based model) or a unified full-body skill embedding space (skill embedding). However, these approaches often struggle to generalize and scale to larger motion datasets. In this work, we introduce a novel skill learning framework, ModSkill, that decouples complex full-body skills into compositional, modular skills for independent body parts, leveraging body structure-inspired inductive bias to enhance skill learning performance. Our framework features a skill modularization attention mechanism that processes policy observations into modular skill embeddings that guide low-level controllers for each body part. We further propose Generative Adaptive Sampling for Active Skill Learning, using large motion generation models to adaptively enhance policy learning in challenging tracking scenarios. Results show that this modularized skill learning framework, enhanced by generative sampling, outperforms existing methods in precise full-body motion tracking and enables reusable skill embeddings for diverse goal-driven tasks.
Improving Multimodal Learning via Imbalanced Learning
Authors: Shicai Wei; Chunbo Luo; Yang Luo
Venue: ICCV 2025 (main)

Abstract: Multimodal learning often encounters the under-optimized problem and may perform worse than unimodal learning. Existing approaches attribute this issue to imbalanced learning across modalities and tend to address it through gradient balancing. However, this paper argues that balanced learning is not the optimal setting for multimodal learning. With bias-variance analysis, we prove that imbalanced dependency on each modality obeying the inverse ratio of their variances contributes to optimal performance. To this end, we propose the Asymmetric Representation Learning(ARL) strategy to assist multimodal learning via imbalanced optimization. ARL introduces auxiliary regularizers for each modality encoder to calculate their prediction variance. ARL then calculates coefficients via the unimodal variance to re-weight the optimization of each modality, forcing the modality dependence ratio to be inversely proportional to the modality variance ratio. Moreover, to minimize the generalization error, ARL further introduces the prediction bias of each modality and jointly optimizes them with multimodal loss. Notably, all auxiliary regularizers share parameters with the multimodal model and rely only on the modality representation. Thus the proposed ARL strategy introduces no extra parameters and is independent of the structures and fusion methods of the multimodal model. Finally, extensive experiments on various datasets validate the effectiveness and versatility of ARL.
INTER: Mitigating Hallucination in Large Vision-Language Models by Interaction Guidance Sampling
Authors: Xin Dong; Shichao Dong; Jin Wang; Jing Huang; Li Zhou; Zenghui Sun; Lihua Jing; Jinsong Lan; Xiaoyong Zhu; Bo Zheng
Venue: ICCV 2025 (main)

Abstract: Hallucinations in large vision-language models (LVLMs) pose significant challenges for real-world applications, as LVLMs may generate responses that appear plausible yet remain inconsistent with the associated visual content. This issue rarely occurs in human cognition. We argue that this discrepancy arises from humans' ability to effectively leverage multimodal interaction information in data samples. Specifically, humans typically first gather multimodal information, analyze the interactions across modalities for understanding, and then express their understanding through language. Motivated by this observation, we conduct extensive experiments on popular LVLMs and obtained insights that surprisingly reveal human-like, though less pronounced, cognitive behavior of LVLMs on multimodal samples. Building on these findings, we further propose INTER: Interaction Guidance Sampling, a novel training-free algorithm that mitigate hallucinations without requiring additional data. Specifically, INTER explicitly guides LVLMs to effectively reapply their understanding of multimodal interaction information when generating responses, thereby reducing potential hallucinations. On six benchmarks including VQA and image captioning tasks, INTER achieves an average improvement of up to 3.4% on five LVLMs compared to the state-of-the-art decoding strategy.

Venue: ICCV 2025 (main)

Abstract: The segmentation of forest LiDAR 3D point clouds, including both individual tree and semantic segmentation, is fundamental for advancing forest management and ecological research. However, current approaches often struggle with the complexity and variability of natural forest environments. We present ForestFormer3D, a new unified and end-to-end framework designed for precise individual tree and semantic segmentation. ForestFormer3D incorporates ISA-guided query point selection, a score-based block merging strategy during inference, and a one-to-many association mechanism for effective training. By combining these new components, our model achieves state-of-the-art performance for individual tree segmentation on the newly introduced FOR-instanceV2 dataset, which spans diverse forest types and regions. Additionally, ForestFormer3D generalizes well to unseen test sets (Wytham woods and LAUTx), showcasing its robustness across different forest conditions and sensor modalities. The FOR-instanceV2 dataset and the ForestFormer3D code are publicly available at https://bxiang233.github.io/FF3D/.
