CamGeo: Sparse Camera-Conditioned Image-to-Video Generation with 3D Geometry Priors

ICML 2026poster

Sparse camera-conditioned image-to-video generation presents a pivotal challenge: synthesizing geometrically consistent 3D motion from minimal pose cues. Existing methods, which largely rely on dense supervision or naive interpolation, suffer from severe pose drift and motion discontinuities due to …

POPEN: Preference-Based Optimization and Ensemble for LVLM-Based Reasoning Segmentation

CVPR 2025poster

Existing LVLM-based reasoning segmentation methods often suffer from imprecise segmentation results and hallucinations in their text responses. This paper introduces POPEN, a novel framework designed to address these issues and achieve improved results. POPEN includes a preference-based optimization…

Unlocking the Power of SAM 2 for Few-Shot Segmentation

ICML 2025poster

Few-Shot Segmentation (FSS) aims to learn class-agnostic segmentation on few classes to segment arbitrary classes, but at the risk of overfitting. To address this, some methods use the well-learned knowledge of foundation models (e.g., SAM) to simplify the learning process. Recently, SAM 2 has exten…

Hybrid Mamba for Few-Shot Segmentation

NeurIPS 2024poster

Many few-shot segmentation (FSS) methods use cross attention to fuse support foreground (FG) into query features, regardless of the quadratic complexity. A recent advance Mamba can also well capture intra-sequence dependencies, yet the complexity is only linear. Hence, we aim to devise a cross (atte…
