Dyn-VPP: Video Prediction Policy Optimization for Improved Visual Dynamics

ICML 2026poster

Video action models are a promising foundation for Vision–Language–Action (VLA) because they can learn rich visual dynamics directly from video. However, likelihood-oriented training of diffusion predictors emphasizes globally plausible futures and does not guarantee precision-critical visual dynami…

A Simple Image Segmentation Framework via In-Context Examples

NeurIPS 2024poster

Recently, there have been explorations of generalist segmentation models that can effectively tackle a variety of image segmentation tasks within a unified in-context learning framework. However, these methods still struggle with task ambiguity in in-context segmentation, as not all in-context examp…

Matcher: Segment Anything with One Shot Using All-Purpose Feature Matching

ICLR 2024poster

Powered by large-scale pre-training, vision foundation models exhibit significant potential in open-world image understanding. However, unlike large language models that excel at directly tackling various language tasks, vision foundation models require a task-specific model structure followed by fi…

SegPrompt: Boosting Open-World Segmentation via Category-Level Prompt Learning

ICCV 2023poster

Current closed-set instance segmentation models rely on predefined class labels for each mask during training and evaluation, limiting their ability to detect novel objects. Open-world instance segmentation (OWIS) models address this challenge by detecting unknown objects in a class-agnostic manner.…
