SAM 3: Segment Anything with Concepts

ICLR 2026poster

We present Segment Anything Model (SAM) 3, a unified model that detects, segments, and tracks objects in images and videos based on concept prompts, which we define as either short noun phrases (e.g., “yellow school bus”), image exemplars, or a combination of both. Promptable Concept Segmentation (P…

Perception Encoder: The best visual embeddings are not at the output of the network

NeurIPS 2025oral

We introduce Perception Encoder (PE), a family of state-of-the-art vision encoders for image and video understanding. Traditionally, vision encoders have relied on a variety of pretraining objectives, each excelling at different downstream tasks. Surprisingly, after scaling a carefully tuned image p…

PerceptionLM: Open-Access Data and Models for Detailed Visual Understanding

NeurIPS 2025spotlight

Vision-language models are integral to computer vision research, yet many high-performing models remain closed-source, obscuring their data, design and training recipe. The research community has responded by using distillation from black-box models to label training data, achieving strong benchmark…

SAM 2: Segment Anything in Images and Videos

ICLR 2025oral

We present Segment Anything Model 2 (SAM 2), a foundation model towards solving promptable visual segmentation in images and videos. We build a data engine, which improves model and data via user interaction, to collect the largest video segmentation dataset to date. Our model is a simple transforme…

FACET: Fairness in Computer Vision Evaluation Benchmark

ICCV 2023poster

Computer vision models have known performance disparities across attributes such as gender and skin tone. This means during tasks such as classification and detection, model performance differs for certain classes based on the demographics of the people in the image. These disparities have been show…

Omni3D: A Large Benchmark and Model for 3D Object Detection in the Wild

CVPR 2023poster

Recognizing scenes and objects in 3D from a single image is a longstanding goal of computer vision with applications in robotics and AR/VR. For 2D recognition, large datasets and scalable solutions have led to unprecedented advances. In 3D, existing benchmarks are small in size and approaches specia…

Omnivore: A Single Model for Many Visual Modalities

CVPR 2022oral

Prior work has studied different visual modalities in isolation and developed separate architectures for recognition of images, videos, and 3D data. Instead, in this paper, we propose a single model which excels at classifying images, videos, and single-view 3D data using exactly the same model para…

Worldsheet: Wrapping the World in a 3D Sheet for View Synthesis From a Single Image

ICCV 2021poster

We present Worldsheet, a method for novel view synthesis using just a single RGB image as input. The main insight is that simply shrink-wrapping a planar mesh sheet onto the input image, consistent with the learned intermediate depth, captures underlying geometry sufficient to generate photorealisti…

C3DPO: Canonical 3D Pose Networks for Non-Rigid Structure From Motion

ICCV 2019oral

We propose C3DPO, a method for extracting 3D models of deformable objects from 2D keypoint annotations in unconstrained images. We do so by learning a deep network that reconstructs a 3D object from a single view at a time, accounting for partial occlusions, and explicitly factoring the effects of v…
