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.

尽管最先进的物体检测方法显示出令人信服的性能,但模型通常对对抗的攻击和分发数据不稳健。我们介绍了一个新的数据集,天然对手对象(Nao),以评估物体检测模型的稳健性。 Nao包含7,934个图像和9,943个对象,这些对象未经修改,代表了现实世界的情景,但导致最先进的检测模型以高信任误入歧途。与标准MSCOCO验证集相比,在NAO上评估时,高效的平均平均精度(MAP)降低74.5%。此外,通过比较各种对象检测架构,我们发现Mscoco验证集上的更好性能不一定转化为NAO的更好性能,这表明不能通过培训更准确的模型来简单地实现鲁棒性。我们进一步调查为什么NA​​O中难以检测和分类的原因。洗牌图像贴片的实验表明,模型对局部质地过于敏感。此外,使用集成梯度和背景替换,我们发现检测模型依赖于边界框内的像素信息,并且在预测类标签时对背景上下文不敏感。 Nao可以在https://drive.google.com/drive/folders/15p8sowojku6sseihlets86orfytgezi8下载。

Although Deep Neural Networks (DNNs) have achieved impressive results in computer vision, their exposed vulnerability to adversarial attacks remains a serious concern. A series of works has shown that by adding elaborate perturbations to images, DNNs could have catastrophic degradation in performance metrics. And this phenomenon does not only exist in the digital space but also in the physical space. Therefore, estimating the security of these DNNs-based systems is critical for safely deploying them in the real world, especially for security-critical applications, e.g., autonomous cars, video surveillance, and medical diagnosis. In this paper, we focus on physical adversarial attacks and provide a comprehensive survey of over 150 existing papers. We first clarify the concept of the physical adversarial attack and analyze its characteristics. Then, we define the adversarial medium, essential to perform attacks in the physical world. Next, we present the physical adversarial attack methods in task order: classification, detection, and re-identification, and introduce their performance in solving the trilemma: effectiveness, stealthiness, and robustness. In the end, we discuss the current challenges and potential future directions.

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.

Object detection is an important and challenging problem in computer vision. Although the past decade has witnessed major advances in object detection in natural scenes, such successes have been slow to aerial imagery, not only because of the huge variation in the scale, orientation and shape of the object instances on the earth's surface, but also due to the scarcity of wellannotated datasets of objects in aerial scenes. To advance object detection research in Earth Vision, also known as Earth Observation and Remote Sensing, we introduce a large-scale Dataset for Object deTection in Aerial images (DOTA). To this end, we collect 2806 aerial images from different sensors and platforms. Each image is of the size about 4000 × 4000 pixels and contains objects exhibiting a wide variety of scales, orientations, and shapes. These DOTA images are then annotated by experts in aerial image interpretation using 15 common object categories. The fully annotated DOTA images contains 188, 282 instances, each of which is labeled by an arbitrary (8 d.o.f.) quadrilateral. To build a baseline for object detection in Earth Vision, we evaluate state-of-the-art object detection algorithms on DOTA. Experiments demonstrate that DOTA well represents real Earth Vision applications and are quite challenging.

在计算机视觉中,构建实例检测模型并可以处理稀有对象类别是一个重要的挑战。但是,数据收集方法和指标缺乏对使用神经网络应用实际场景应用的研究。在这里,我们对对象遮挡数据收集和增强方法进行系统研究,在该方法中,我们模仿目标场景中的对象遮挡关系。但是,我们发现对象阻塞的简单机制足够好,并且可以在添加新类别的实际场景中提供可接受的准确性。我们幻想的是,只有数百个类别的50万培训数据集中添加15张新类别的图像,可以在看不见的测试数据集中提供这个新类别95%的准确性,其中包括数千张此类别的图像。

This paper presents a new large scale multi-person tracking dataset -- \texttt{PersonPath22}, which is over an order of magnitude larger than currently available high quality multi-object tracking datasets such as MOT17, HiEve, and MOT20 datasets. The lack of large scale training and test data for this task has limited the community's ability to understand the performance of their tracking systems on a wide range of scenarios and conditions such as variations in person density, actions being performed, weather, and time of day. \texttt{PersonPath22} dataset was specifically sourced to provide a wide variety of these conditions and our annotations include rich meta-data such that the performance of a tracker can be evaluated along these different dimensions. The lack of training data has also limited the ability to perform end-to-end training of tracking systems. As such, the highest performing tracking systems all rely on strong detectors trained on external image datasets. We hope that the release of this dataset will enable new lines of research that take advantage of large scale video based training data.

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。

It is desirable for detection and classification algorithms to generalize to unfamiliar environments, but suitable benchmarks for quantitatively studying this phenomenon are not yet available. We present a dataset designed to measure recognition generalization to novel environments. The images in our dataset are harvested from twenty camera traps deployed to monitor animal populations. Camera traps are fixed at one location, hence the background changes little across images; capture is triggered automatically, hence there is no human bias. The challenge is learning recognition in a handful of locations, and generalizing animal detection and classification to new locations where no training data is available. In our experiments state-of-the-art algorithms show excellent performance when tested at the same location where they were trained. However, we find that generalization to new locations is poor, especially for classification systems.

The success of deep learning in vision can be attributed to: (a) models with high capacity; (b) increased computational power; and (c) availability of large-scale labeled data. Since 2012, there have been significant advances in representation capabilities of the models and computational capabilities of GPUs. But the size of the biggest dataset has surprisingly remained constant. What will happen if we increase the dataset size by 10× or 100×? This paper takes a step towards clearing the clouds of mystery surrounding the relationship between 'enormous data' and visual deep learning. By exploiting the JFT-300M dataset which has more than 375M noisy labels for 300M images, we investigate how the performance of current vision tasks would change if this data was used for representation learning. Our paper delivers some surprising (and some expected) findings. First, we find that the performance on vision tasks increases logarithmically based on volume of training data size. Second, we show that representation learning (or pretraining) still holds a lot of promise. One can improve performance on many vision tasks by just training a better base model. Finally, as expected, we present new state-of-theart results for different vision tasks including image classification, object detection, semantic segmentation and human pose estimation. Our sincere hope is that this inspires vision community to not undervalue the data and develop collective efforts in building larger datasets.

在过去的十年中,深度学习急剧改变了传统的手工艺特征方式,具有强大的功能学习能力,从而极大地改善了传统任务。然而,最近已经证明了深层神经网络容易受到对抗性例子的影响,这种恶意样本由小型设计的噪音制作,误导了DNNs做出错误的决定,同时仍然对人类无法察觉。对抗性示例可以分为数字对抗攻击和物理对抗攻击。数字对抗攻击主要是在实验室环境中进行的,重点是改善对抗性攻击算法的性能。相比之下,物理对抗性攻击集中于攻击物理世界部署的DNN系统,这是由于复杂的物理环境(即亮度,遮挡等),这是一项更具挑战性的任务。尽管数字对抗和物理对抗性示例之间的差异很小,但物理对抗示例具有特定的设计,可以克服复杂的物理环境的效果。在本文中,我们回顾了基于DNN的计算机视觉任务任务中的物理对抗攻击的开发,包括图像识别任务,对象检测任务和语义细分。为了完整的算法演化,我们将简要介绍不涉及身体对抗性攻击的作品。我们首先提出一个分类方案,以总结当前的物理对抗攻击。然后讨论现有的物理对抗攻击的优势和缺点,并专注于用于维持对抗性的技术,当应用于物理环境中时。最后,我们指出要解决的当前身体对抗攻击的问题并提供有前途的研究方向。

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.
