我们介绍了一些源自摄影师的本地化数据集，他们实际上试图了解他们拍摄的图像中的视觉内容。它包括有4,500多个视觉障碍者拍摄的超过4,500张图像中的100个类别的近10,000个细分。与现有的少数弹射对象检测和实例分段数据集相比，我们的数据集是第一个在对象中找到孔（例如，在我们的分段的12.3 \％中找到），它显示的对象相对于占据相对于尺寸的范围较大。图像和文本在我们的对象中的常见五倍以上（例如，在我们的分割的22.4％中找到）。对三种现代少量定位算法的分析表明，它们概括为我们的新数据集。这些算法通常很难找到带有孔，非常小且非常大的物体以及缺乏文本的物体的对象。为了鼓励更大的社区致力于这些尚未解决的挑战，我们在https://vizwiz.org上公开分享了带注释的少数数据集。

We present a new dataset with the goal of advancing the state-of-the-art in object recognition by placing the question of object recognition in the context of the broader question of scene understanding. This is achieved by gathering images of complex everyday scenes containing common objects in their natural context. Objects are labeled using per-instance segmentations to aid in precise object localization. Our dataset contains photos of 91 objects types that would be easily recognizable by a 4 year old. With a total of 2.5 million labeled instances in 328k images, the creation of our dataset drew upon extensive crowd worker involvement via novel user interfaces for category detection, instance spotting and instance segmentation. We present a detailed statistical analysis of the dataset in comparison to PASCAL, ImageNet, and SUN. Finally, we provide baseline performance analysis for bounding box and segmentation detection results using a Deformable Parts Model.

Progress on object detection is enabled by datasets that focus the research community's attention on open challenges. This process led us from simple images to complex scenes and from bounding boxes to segmentation masks. In this work, we introduce LVIS (pronounced 'el-vis'): a new dataset for Large Vocabulary Instance Segmentation. We plan to collect ∼2 million high-quality instance segmentation masks for over 1000 entry-level object categories in 164k images. Due to the Zipfian distribution of categories in natural images, LVIS naturally has a long tail of categories with few training samples. Given that state-of-the-art deep learning methods for object detection perform poorly in the low-sample regime, we believe that our dataset poses an important and exciting new scientific challenge. LVIS is available at http://www.lvisdataset.org.

Semantic understanding of visual scenes is one of the holy grails of computer vision. Despite efforts of the community in data collection, there are still few image datasets covering a wide range of scenes and object categories with pixel-wise annotations for scene understanding. In this work, we present a densely annotated dataset ADE20K, which spans diverse annotations of scenes, objects, parts of objects, and in some cases even parts of parts. Totally there are 25k images of the complex everyday scenes containing a variety of objects in their natural spatial context. On average there are 19.5 instances and 10.5 object classes per image. Based on ADE20K, we construct benchmarks for scene parsing and instance segmentation. We provide baseline performances on both of the benchmarks and re-implement the state-ofthe-art models for open source. We further evaluate the effect of synchronized batch normalization and find that a reasonably large batch size is crucial for the semantic segmentation performance. We show that the networks trained on ADE20K are able to segment a wide variety of scenes and objects 1 .

Despite progress in perceptual tasks such as image classification, computers still perform poorly on cognitive tasks such as image description and question answering. Cognition is core to tasks that involve not just recognizing, but reasoning about our visual world. However, models used to tackle the rich content in images for cognitive tasks are still being trained using the same datasets designed for perceptual tasks. To achieve success at cognitive tasks, models need to understand the interactions and relationships between objects in

The PASCAL Visual Object Classes (VOC) challenge is a benchmark in visual object category recognition and detection, providing the vision and machine learning communities with a standard dataset of images and annotation, and standard evaluation procedures. Organised annually from 2005 to present, the challenge and its associated dataset has become accepted as the benchmark for object detection.This paper describes the dataset and evaluation procedure. We review the state-of-the-art in evaluated methods for both classification and detection, analyse whether the methods are statistically different, what they are learning from the images (e.g. the object or its context), and what the methods find easy or confuse. The paper concludes with lessons learnt in the three year history of the challenge, and proposes directions for future improvement and extension.

Massive data corpora like WebText, Wikipedia, Conceptual Captions, WebImageText, and LAION have propelled recent dramatic progress in AI. Large neural models trained on such datasets produce impressive results and top many of today's benchmarks. A notable omission within this family of large-scale datasets is 3D data. Despite considerable interest and potential applications in 3D vision, datasets of high-fidelity 3D models continue to be mid-sized with limited diversity of object categories. Addressing this gap, we present Objaverse 1.0, a large dataset of objects with 800K+ (and growing) 3D models with descriptive captions, tags, and animations. Objaverse improves upon present day 3D repositories in terms of scale, number of categories, and in the visual diversity of instances within a category. We demonstrate the large potential of Objaverse via four diverse applications: training generative 3D models, improving tail category segmentation on the LVIS benchmark, training open-vocabulary object-navigation models for Embodied AI, and creating a new benchmark for robustness analysis of vision models. Objaverse can open new directions for research and enable new applications across the field of AI.

弱监督的对象本地化（WSOL）旨在学习仅使用图像级类别标签编码对象位置的表示形式。但是，许多物体可以在不同水平的粒度标记。它是动物，鸟还是大角的猫头鹰？我们应该使用哪些图像级标签？在本文中，我们研究了标签粒度在WSOL中的作用。为了促进这项调查，我们引入了Inatloc500，这是一个新的用于WSOL的大规模细粒基准数据集。令人惊讶的是，我们发现选择正确的训练标签粒度比选择最佳的WSOL算法提供了更大的性能。我们还表明，更改标签粒度可以显着提高数据效率。

The Flickr30k dataset has become a standard benchmark for sentence-based image description. This paper presents Flickr30k Entities, which augments the 158k captions from Flickr30k with 244k coreference chains, linking mentions of the same entities across different captions for the same image, and associating them with 276k manually annotated bounding boxes. Such annotations are essential for continued progress in automatic image description and grounded language understanding. They enable us to define a new benchmark for localization of textual entity mentions in an image. We present a strong baseline for this task that combines an image-text embedding, detectors for common objects, a color classifier, and a bias towards selecting larger objects. While our baseline rivals in accuracy more complex state-of-the-art models, we show that its gains cannot be easily parlayed into improvements on such tasks as image-sentence retrieval, thus underlining the limitations of current methods and the need for further research.

对人类对象相互作用的理解在第一人称愿景（FPV）中至关重要。遵循相机佩戴者操纵的对象的视觉跟踪算法可以提供有效的信息，以有效地建模此类相互作用。在过去的几年中，计算机视觉社区已大大提高了各种目标对象和场景的跟踪算法的性能。尽管以前有几次尝试在FPV域中利用跟踪器，但仍缺少对最先进跟踪器的性能的有条理分析。这项研究差距提出了一个问题，即应使用当前的解决方案``现成''还是应进行更多特定领域的研究。本文旨在为此类问题提供答案。我们介绍了FPV中单个对象跟踪的首次系统研究。我们的研究广泛分析了42个算法的性能，包括通用对象跟踪器和基线FPV特定跟踪器。分析是通过关注FPV设置的不同方面，引入新的绩效指标以及与FPV特定任务有关的。这项研究是通过引入Trek-150（由150个密集注释的视频序列组成的新型基准数据集）来实现的。我们的结果表明，FPV中的对象跟踪对当前的视觉跟踪器构成了新的挑战。我们强调了导致这种行为的因素，并指出了可能的研究方向。尽管遇到了困难，但我们证明了跟踪器为需要短期对象跟踪的FPV下游任务带来好处。我们预计，随着新的和FPV特定的方法学会得到研究，通用对象跟踪将在FPV中受欢迎。

为了使AI安全地在医院，学校和工作场所等现实世界中安全部署，它必须能够坚定地理解物理世界。这种推理的基础是物理常识：了解可用对象的物理特性和提供的能力，如何被操纵以及它们如何与其他对象进行交互。物理常识性推理从根本上是一项多感官任务，因为物理特性是通过多种模式表现出来的，其中两个是视觉和声学。我们的论文通过贡献PACS来朝着现实世界中的物理常识推理：第一个用于物理常识属性注释的视听基准。 PACS包含13,400对答案对，涉及1,377个独特的物理常识性问题和1,526个视频。我们的数据集提供了新的机会来通过将音频作为此多模式问题的核心组成部分来推进物理推理的研究领域。使用PACS，我们在我们的新挑战性任务上评估了多种最先进的模型。尽管某些模型显示出令人鼓舞的结果（精度为70％），但它们都没有人类的绩效（精度为95％）。我们通过证明多模式推理的重要性并为未来的研究提供了可能的途径来结束本文。

Existing image classification datasets used in computer vision tend to have a uniform distribution of images across object categories. In contrast, the natural world is heavily imbalanced, as some species are more abundant and easier to photograph than others. To encourage further progress in challenging real world conditions we present the iNaturalist species classification and detection dataset, consisting of 859,000 images from over 5,000 different species of plants and animals. It features visually similar species, captured in a wide variety of situations, from all over the world. Images were collected with different camera types, have varying image quality, feature a large class imbalance, and have been verified by multiple citizen scientists. We discuss the collection of the dataset and present extensive baseline experiments using state-of-the-art computer vision classification and detection models. Results show that current nonensemble based methods achieve only 67% top one classification accuracy, illustrating the difficulty of the dataset. Specifically, we observe poor results for classes with small numbers of training examples suggesting more attention is needed in low-shot learning.
