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…

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…

ConvNeXt V2: Co-Designing and Scaling ConvNets With Masked Autoencoders

CVPR 2023poster

Driven by improved architectures and better representation learning frameworks, the field of visual recognition has enjoyed rapid modernization and performance boost in the early 2020s. For example, modern ConvNets, represented by ConvNeXt models, have demonstrated strong performance across differen…

Scaling Language-Image Pre-Training via Masking

CVPR 2023poster

We present Fast Language-Image Pre-training (FLIP), a simple and more efficient method for training CLIP. Our method randomly masks out and removes a large portion of image patches during training. Masking allows us to learn from more image-text pairs given the same wall-clock time and contrast more…

UniT3D: A Unified Transformer for 3D Dense Captioning and Visual Grounding

ICCV 2023poster

Performing 3D dense captioning and visual grounding requires a common and shared understanding of the underlying multimodal relationships. However, despite some previous attempts on connecting these two related tasks with highly task-specific neural modules, it remains understudied how to explicitly…

FLAVA: A Foundational Language and Vision Alignment Model

CVPR 2022poster

State-of-the-art vision and vision-and-language models rely on large-scale visio-linguistic pretraining for obtaining good performance on a variety of downstream tasks. Generally, such models are often either cross-modal (contrastive) or multi-modal (with earlier fusion) but not both; and they often…

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…

Iterative Answer Prediction With Pointer-Augmented Multimodal Transformers for TextVQA

CVPR 2020oral

Many visual scenes contain text that carries crucial information, and it is thus essential to understand text in images for downstream reasoning tasks. For example, a deep water label on a warning sign warns people about the danger in the scene. Recent work has explored the TextVQA task that require…

TextCaps: a Dataset for Image Captioning with Reading Comprehension

ECCV 2020poster

Image descriptions can help visually impaired people to quickly understand the image content. While we made significant progress in automatically describing images and optical character recognition, current approaches are unable to include written text in their descriptions, although text is omnipre…

Explainable Neural Computation via Stack Neural Module Networks

ECCV 2018poster

In complex inferential tasks like question answering, machine learning models must confront two challenges: the need to implement a compositional reasoning process, and, in many applications, the need for this reasoning process to be interpretable to assist users in both development and prediction.…

Speaker-Follower Models for Vision-and-Language Navigation

NeurIPS 2018poster

Navigation guided by natural language instructions presents a challenging reasoning problem for instruction followers. Natural language instructions typically identify only a few high-level decisions and landmarks rather than complete low-level motor behaviors; much of the missing information must b…

Learning to Reason: End-To-End Module Networks for Visual Question Answering

ICCV 2017spotlight

Natural language questions are inherently compositional, and many are most easily answered by reasoning about their decomposition into modular sub-problems. For example, to answer "is there an equal number of balls and boxes?" we can look for balls, look for boxes, count them, and compare the result…

Modeling Relationships in Referential Expressions With Compositional Modular Networks

CVPR 2017spotlight

People often refer to entities in an image in terms of their relationships with other entities. For example, "the black cat sitting under the table" refers to both a "black cat" entity and its relationship with another "table" entity. Understanding these relationships is essential for interpreting a…

Spatial Semantic Regularisation for Large Scale Object Detection

ICCV 2015poster

Large scale object detection with thousands of classes introduces the problem of many contradicting false positive detections, which have to be suppressed. Class-independent non-maximum suppression has traditionally been used for this step, but it does not scale well as the number of classes grows.…
