The Mapillary Vistas Dataset is a novel, largescale street-level image dataset containing 25 000 highresolution images annotated into 66 object categories with additional, instance-specific labels for 37 classes. Annotation is performed in a dense and fine-grained style by using polygons for delineating individual objects. Our dataset is 5× larger than the total amount of fine annotations for Cityscapes and contains images from all around the world, captured at various conditions regarding weather, season and daytime. Images come from different imaging devices (mobile phones, tablets, action cameras, professional capturing rigs) and differently experienced photographers. In such a way, our dataset has been designed and compiled to cover diversity, richness of detail and geographic extent. As default benchmark tasks, we define semantic image segmentation and instance-specific image segmentation, aiming to significantly further the development of state-of-theart methods for visual road-scene understanding.

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 .

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.

为视频中的每个像素分配语义类和跟踪身份的任务称为视频Panoptic分段。我们的工作是第一个在真实世界中瞄准这项任务,需要在空间和时间域中的密集解释。由于此任务的地面真理难以获得,但是,现有数据集是合成构造的或仅在短视频剪辑中稀疏地注释。为了克服这一点,我们介绍了一个包含两个数据集,Kitti-Step和Motchallenge步骤的新基准。数据集包含长视频序列,提供具有挑战性的示例和用于研究长期像素精确分割和在真实条件下跟踪的测试床。我们进一步提出了一种新的评估度量分割和跟踪质量(STQ),其相当余额平衡该任务的语义和跟踪方面,并且更适合评估任意长度的序列。最后,我们提供了几个基线来评估此新具有挑战性数据集的现有方法的状态。我们已将我们的数据集,公制,基准服务器和基准公开提供,并希望这将激发未来的研究。

Robust detection and tracking of objects is crucial for the deployment of autonomous vehicle technology. Image based benchmark datasets have driven development in computer vision tasks such as object detection, tracking and segmentation of agents in the environment. Most autonomous vehicles, however, carry a combination of cameras and range sensors such as lidar and radar. As machine learning based methods for detection and tracking become more prevalent, there is a need to train and evaluate such methods on datasets containing range sensor data along with images. In this work we present nuTonomy scenes (nuScenes), the first dataset to carry the full autonomous vehicle sensor suite: 6 cameras, 5 radars and 1 lidar, all with full 360 degree field of view. nuScenes comprises 1000 scenes, each 20s long and fully annotated with 3D bounding boxes for 23 classes and 8 attributes. It has 7x as many annotations and 100x as many images as the pioneering KITTI dataset. We define novel 3D detection and tracking metrics. We also provide careful dataset analysis as well as baselines for lidar and image based detection and tracking. Data, development kit and more information are available online 1 .

Image segmentation is a key topic in image processing and computer vision with applications such as scene understanding, medical image analysis, robotic perception, video surveillance, augmented reality, and image compression, among many others. Various algorithms for image segmentation have been developed in the literature. Recently, due to the success of deep learning models in a wide range of vision applications, there has been a substantial amount of works aimed at developing image segmentation approaches using deep learning models. In this survey, we provide a comprehensive review of the literature at the time of this writing, covering a broad spectrum of pioneering works for semantic and instance-level segmentation, including fully convolutional pixel-labeling networks, encoder-decoder architectures, multi-scale and pyramid based approaches, recurrent networks, visual attention models, and generative models in adversarial settings. We investigate the similarity, strengths and challenges of these deep learning models, examine the most widely used datasets, report performances, and discuss promising future research directions in this area.

Datasets drive vision progress, yet existing driving datasets are impoverished in terms of visual content and supported tasks to study multitask learning for autonomous driving. Researchers are usually constrained to study a small set of problems on one dataset, while real-world computer vision applications require performing tasks of various complexities. We construct BDD100K 1 , the largest driving video dataset with 100K videos and 10 tasks to evaluate the exciting progress of image recognition algorithms on autonomous driving. The dataset possesses geographic, environmental, and weather diversity, which is useful for training models that are less likely to be surprised by new conditions. Based on this diverse dataset, we build a benchmark for heterogeneous multitask learning and study how to solve the tasks together. Our experiments show that special training strategies are needed for existing models to perform such heterogeneous tasks. BDD100K opens the door for future studies in this important venue.

Panoptic图像分割是计算机视觉任务,即在图像中查找像素组并为其分配语义类别和对象实例标识符。由于其在机器人技术和自动驾驶中的关键应用,图像细分的研究变得越来越流行。因此,研究社区依靠公开可用的基准数据集来推进计算机视觉中的最新技术。但是,由于将图像标记为高昂的成本,因此缺乏适合全景分割的公开地面真相标签。高标签成本还使得将现有数据集扩展到视频域和多相机设置是一项挑战。因此,我们介绍了Waymo Open DataSet:全景视频全景分割数据集,这是一个大型数据集,它提供了用于自主驾驶的高质量的全景分割标签。我们使用公开的Waymo打开数据集生成数据集,利用各种相机图像集。随着时间的推移,我们的标签是一致的,用于视频处理,并且在车辆上安装的多个摄像头保持一致,以了解全景的理解。具体而言,我们为28个语义类别和2,860个时间序列提供标签,这些标签由在三个不同地理位置驾驶的自动驾驶汽车上安装的五个摄像机捕获,从而导致总共标记为100k标记的相机图像。据我们所知,这使我们的数据集比现有的数据集大量数据集大的数量级。我们进一步提出了一个新的基准,用于全景视频全景分割,并根据DeepLab模型家族建立许多强大的基准。我们将公开制作基准和代码。在https://waymo.com/open上找到数据集。

随着深度卷积神经网络的兴起,对象检测在过去几年中取得了突出的进步。但是,这种繁荣无法掩盖小物体检测(SOD)的不令人满意的情况,这是计算机视觉中臭名昭著的挑战性任务之一,这是由于视觉外观不佳和由小目标的内在结构引起的嘈杂表示。此外,用于基准小对象检测方法基准测试的大规模数据集仍然是瓶颈。在本文中,我们首先对小物体检测进行了详尽的审查。然后,为了催化SOD的发展,我们分别构建了两个大规模的小物体检测数据集(SODA),SODA-D和SODA-A,分别集中在驾驶和空中场景上。 SODA-D包括24704个高质量的交通图像和277596个9个类别的实例。对于苏打水,我们收集2510个高分辨率航空图像,并在9个类别上注释800203实例。众所周知,拟议的数据集是有史以来首次尝试使用针对多类SOD量身定制的大量注释实例进行大规模基准测试。最后,我们评估主流方法在苏打水上的性能。我们预计发布的基准可以促进SOD的发展,并产生该领域的更多突破。数据集和代码将很快在:\ url {https://shaunyuan22.github.io/soda}上。

由于大规模数据集的可用性,通常在特定位置和良好的天气条件下收集的大规模数据集,近年来,自动驾驶汽车的感知进展已加速。然而,为了达到高安全要求,这些感知系统必须在包括雪和雨在内的各种天气条件下进行稳健运行。在本文中,我们提出了一个新数据集,以通过新颖的数据收集过程启用强大的自动驾驶 - 在不同场景(Urban,Highway,乡村,校园),天气,雪,雨,阳光下,沿着15公里的路线反复记录数据),时间(白天/晚上)以及交通状况(行人,骑自行车的人和汽车)。该数据集包括来自摄像机和激光雷达传感器的图像和点云,以及高精度GPS/ins以在跨路线上建立对应关系。该数据集包括使用Amodal掩码捕获部分遮挡和3D边界框的道路和对象注释。我们通过分析基准在道路和对象,深度估计和3D对象检测中的性能来证明该数据集的独特性。重复的路线为对象发现,持续学习和异常检测打开了新的研究方向。链接到ITHACA365:https://ithaca365.mae.cornell.edu/

最先进的语义或实例分割深度神经网络(DNN)通常在封闭的语义类上培训。因此,它们的装备不适用于处理以前的未持续的对象。然而,检测和定位这些物体对于安全关键应用至关重要,例如对自动驾驶的感知,特别是如果它们出现在前方的道路上。虽然某些方法已经解决了异常或分发的对象分割的任务,但由于缺乏固体基准,在很大程度上存在进展仍然缓慢;现有数据集由合成数据组成,或遭受标签不一致。在本文中,我们通过介绍“SegmentMeifyOUCAN”基准来弥合这个差距。我们的基准解决了两个任务:异常对象分割,这将考虑任何以前的未持续的对象类别;和道路障碍分割,它侧重于道路上的任何物体,可能是已知的或未知的。我们将两个相应的数据集与执行深入方法分析的测试套件一起提供,考虑到已建立的像素 - 明智的性能度量和最近的组件 - 明智的,这对对象尺寸不敏感。我们凭经验评估了多种最先进的基线方法,包括使用我们的测试套件在我们的数据集和公共数据上专门为异常/障碍分割而设计的多种型号。异常和障碍分割结果表明,我们的数据集有助于数据景观的多样性和难度。
