Automatic Annotation of Object Instances by Region-Based Recurrent Neural Networks 基于区域递归神经网络的对象实例自动标注
Ionut Ficiu, Radu Stilpeanu, Cosmin Toca, A. Petre, C. Patrascu, M. Ciuc
In recent years, a wide variety of automatic, semiautomatic and manual approaches to image annotation have been proposed. These prerequisites have been driven by continuous advances of deep learning algorithms that often encounter the problem of insufficient or inappropriate training data, as well as sub-par markings’ accuracy which can have a direct impact on the model’s performance regardless. The main contribution of this paper is the development of a complex annotation framework able to automatically generate high-quality markings. The annotation work-flow aims to be an iterative process allowing automatic labeling of object bounding boxes, while simultaneously predicting the polygon outlining the object instance inside the box. The markings’ format is fully compatible with COCO Detection & Panoptic APIs that provide open-source interfaces for loading, parsing, and visualizing annotations. Following the completion of the research project funding this research, the code will be publicly available.
近年来,人们提出了各种各样的自动、半自动和手动图像标注方法。这些先决条件是由深度学习算法的不断进步所驱动的,这些算法经常遇到训练数据不足或不适当的问题,以及标记的准确性低于标准,这可能会对模型的性能产生直接影响。本文的主要贡献是开发了一个能够自动生成高质量标记的复杂注释框架。标注工作流程旨在成为一个迭代过程,允许自动标记对象边界框,同时预测框内对象实例的多边形轮廓。标记的格式与COCO Detection & Panoptic api完全兼容,后者提供了用于加载、解析和可视化注释的开源接口。在资助本研究的研究项目完成后,代码将向公众开放。

Maria-Iuliana Bocicor, A. Molnar, Iuliana Marin, N. Goga, Raul Valor Perez, D. Cuesta-Frau
The current trend of population ageing leads to an increasingly larger population of older adults, who understandabl desire to continue living an independent and fulfilling life in their home and within their communities. While traditionally seen as a societal issue, we are currently at a point where advancement in science and technology enables us to augment human help with ambient assisted living solutions. This paper is the result of research and development undertaken within the framework of a European Union research project targeting the development of a cyber-physical system for assisted living and home monitoring. The system integrates an unobtrusive networkof wireless sensors with server software to provide ambient monitoring, location detection and real-time alerting. The present paper is focused on the system’s intelligent software components.The first is a business rules engine that can be configured to send real-time alerts in the case of certain ambient conditions or whe the location of the monitored person shows signification alteration from their usual movement patterns. The second component is a artificial intelligence-based location predictor, used to provide the monitored person’s location. Discrepancies between actual an expected location are used by the rule engine to trigger real-time alerts to caregivers.
目前人口老龄化的趋势导致老年人口越来越多,他们希望在家中和社区中继续过独立和充实的生活,这是可以理解的。虽然传统上被视为一个社会问题,但我们目前正处于科学技术进步使我们能够通过环境辅助生活解决方案来增强人类帮助的阶段。本文是在欧盟研究项目框架内进行的研究和开发的结果,该项目旨在开发用于辅助生活和家庭监控的网络物理系统。该系统集成了一个不显眼的无线传感器网络和服务器软件,提供环境监测、位置检测和实时警报。本文重点研究了该系统的智能软件组件。第一个是业务规则引擎,可以将其配置为在某些环境条件下发送实时警报,或者当被监视人员的位置显示与其通常的运动模式有重大变化时。第二个组件是基于人工智能的位置预测器,用于提供被监控人员的位置。规则引擎使用实际位置与预期位置之间的差异来触发对护理人员的实时警报。

Dorin Moldovan, Adrian Olosutean, V. Chifu, C. Pop, T. Cioara, I. Anghel, I. Salomie
Dementia is still an incurable disease that affects a big part of the population nowadays. It affects millions of people worldwide and the number is expected to increase significantly in the next decades. The persons with dementia face difficulties in performing the daily living activities (DLAs) due to movement disorders, poor coordination and memory loss and they need support from family members or health care professionals. In this paper several Big Data techniques are explored for the analysis of the DLAs of the people that have dementia in order to identify behavioral patterns. In particular this paper: (1) presents how the K-Means Clustering algorithm can be used for the identification of the number of types of DLAs performed by a person with dementia in a day, (2) presents how to apply the Collaborative Filtering algorithm for the prediction of the frequency of the DLAs and (3) compares several classification and regression algorithms for the identification of the days with anomalies with respect to a baseline and for the prediction of the durations of the DLAs of the people with dementia using a prototype developed in-house. Two datasets used in the experiments are taken from literature and a third dataset is derived from one of the previous datasets and used as simulated data.
如今,痴呆症仍然是一种无法治愈的疾病,影响着很大一部分人口。它影响着全世界数百万人,预计在未来几十年里,这一数字将显著增加。痴呆症患者由于运动障碍、协调能力差和记忆力丧失,在进行日常生活活动方面面临困难,他们需要家庭成员或保健专业人员的支持。本文探讨了几种大数据技术,用于分析痴呆症患者的dla,以识别行为模式。特别是本文:(1)介绍了如何使用K-Means聚类算法来识别痴呆症患者在一天内执行的DLAs类型的数量;(2)介绍了如何应用协同过滤算法来预测DLAs的频率;(3)比较了几种分类和回归算法,用于识别与基线相关的异常天数,并使用内部开发的原型来预测痴呆症患者的DLAs持续时间。实验中使用的两个数据集来自文献,第三个数据集来自先前的一个数据集并用作模拟数据。

Understanding and Making Sense of Maritime Navigation Datasets 理解和理解海上导航数据集
Liviu Nastase, Catalin Negru, Florin Pop
Maritime transport represents the primary transportation for the global economy, almost 90% of the goods worldwide are shipped by sea, including petrol, food, cars, electronic components and other raw materials. On the other hand, maritime transport is responsible for 3% to 4% of the total human-caused carbon emissions. The current marine infrastructure has systems in place to track and monitor ships during their voyages. One of those systems is the automatic identification system (AIS). This paper aims to create a system that use AIS data to offer an improved understanding and additional insights on maritime transport. Using this naval system traffic is better understood, and with time its efficiency would be improved. The proposed system presents ship’s details, destinations and locations data based on AIS data. We can use this system to create further functionalities for better and detailed analysis on maritime transport.

A Method for Automatic Pole Detection from Urban Video Scenes using Stereo Vision 基于立体视觉的城市视频场景极点自动检测方法
Bianca-Cerasela-Zelia Blaga, S. Nedevschi
Pole-like structures such as the ones used for traffic lights, traffic signs, utility poles, lampposts or even trees are encountered everywhere in urban scenarios. Because they are robust landmarks, they can help solve problems from the autonomous driving domain, such as localization, mapping, and navigation. In this paper, we propose a method that extracts poles from stereo camera information. First, the intensity images are analyzed to find areas of interest that could contain the desired landmarks. Then, we build U- and V-disparity maps that are used to estimate the position of the poles on the road images. Finally, we cluster the candidate regions of interest, which are then further refined to eliminate outliers. We also use an algorithm for enhancing the illumination of nighttime images, so that we can detect the desired landmarks at different times of the day. Our system is able to extract poles from the same road, on different driving conditions, days, or lanes, it accounts for the possibility of occlusions, and we are able to obtain both a relative and an absolute localization.
杆状结构,如用于交通信号灯、交通标志、电线杆、灯柱甚至树木的杆状结构,在城市场景中随处可见。因为它们是鲁棒地标,它们可以帮助解决自动驾驶领域的问题,如定位、地图和导航。本文提出了一种从立体摄像机信息中提取极点的方法。首先,对强度图像进行分析,以找到可能包含所需地标的感兴趣区域。然后,我们构建U-和v -视差图,用于估计道路图像上极点的位置。最后,我们对感兴趣的候选区域进行聚类,然后进一步细化以消除异常值。我们还使用了一种算法来增强夜间图像的照明,这样我们就可以在一天中的不同时间检测到所需的地标。我们的系统能够从同一条道路,不同的驾驶条件,天数或车道中提取极点,它考虑了闭塞的可能性,并且我们能够获得相对和绝对定位。

Learning Web Content Extraction with DOM Features 学习用DOM特征提取Web内容
Nichita Utiu, Vlad-Sebastian Ionescu
Content extraction is the process that aims to separate the main content of web pages from the bulk of template and decorative components. We present a method of doing this which achieves competitive performance on the Cleaneval dataset and sets a new state-of-the-art with an F1 score of 0.96 on the Dragnet dataset. We accomplish this by modeling the task as a classification problem over HTML tags using features based on information from the DOM tree. Not only do we obtain a performance increase over current methods, but we do so with minimal feature engineering and without the extensive preprocessing steps of other methods.
内容抽取是指将网页的主要内容从大量模板和装饰组件中分离出来的过程。我们提出了一种方法,该方法在Cleaneval数据集上实现了具有竞争力的性能,并在Dragnet数据集上设置了F1分数为0.96的新状态。我们通过使用基于DOM树信息的特性将任务建模为HTML标记上的分类问题来实现这一点。与现有方法相比,我们不仅获得了性能提升,而且只需要最少的特征工程,而不需要其他方法的大量预处理步骤。

Nicusor Iancu-Puiu, M. Marcu
Bluetooth technology is widely used nowadays by mobile, embedded and IoT devices. One important aspect that should be addressed by battery powered solutions is energy efficiency, where communication takes an important share or the total power consumption. The main goal of our research is to analyze and profile Bluetooth communication from power consumption and performance perspectives. This analysis is further used to optimize communication on battery powered devices in order to increase the battery lifetime of the application. In our work we managed to identify and measure power consumption and timings of BLE communication at event level with high accuracy.

Multimodal sparse LIDAR object tracking in clutter 杂波条件下多模态稀疏激光雷达目标跟踪
Mircea Paul Muresan, S. Nedevschi
one of the key components of the perception system in an autonomous vehicle or ADAS is the target tracking module. Using target tracking in the sea of clutter, self-driving cars are able to better understand the environment and make predictions about the surrounding objects. Cuboids obtained from a sparse LIDAR often exhibit a fluctuating behavior due to segmentation problems and errors accumulated from the motion correction module. Furthermore, targets in real life scenarios do not move in a predictable manner, so it is very difficult for a classical motion model to describe the complex behavior of any road objects in such cases. In this paper we propose a two-step data association scheme that efficiently and effectively finds correspondences between tracks and measurements. Then we aim to generate better position estimates for objects with an ambiguous dynamic behavior by associating and combining the results from two different motion models. The proposed solution runs in real time and it was validated using a high precision GPS, and also by projecting the prediction results in the corresponding intensity image and assessing whether the prediction falls on the correct item.
自动驾驶汽车或ADAS感知系统的关键组件之一是目标跟踪模块。通过在混乱的海洋中进行目标跟踪,自动驾驶汽车能够更好地了解环境,并对周围的物体做出预测。稀疏激光雷达获得的长方体通常由于分割问题和运动校正模块积累的误差而表现出波动行为。此外,现实生活中的目标并不以可预测的方式移动,因此经典运动模型很难描述任何道路物体在这种情况下的复杂行为。在本文中,我们提出了一种两步数据关联方案,该方案可以高效地找到轨迹和测量值之间的对应关系。然后,我们的目标是通过关联和结合两种不同运动模型的结果,对具有模糊动态行为的物体产生更好的位置估计。该方法可以实时运行,并通过高精度GPS进行验证,还可以将预测结果投影到相应的强度图像中,并评估预测是否落在正确的项目上。

Segment Trees based Traffic Congestion Avoidance in Connected Cars Context 基于路段树的网联汽车交通拥堵避免研究
Ioan Stan, Dan Toderici, R. Potolea
Nowadays traffic congestion in cities is one of the main challenges that drivers are facing. Cities administration doesn’t always manage to handle this challenge with success and the increasing number of cars makes the situation worse. Navigation Systems, besides generating routes between a starting and ending point, can be used to predict and avoid traffic congestion. In this paper we propose a novel solution for traffic information representation in connected cars context. The strategy is based on segment trees data structure and was integrated into an industry navigation system by enhancing routing algorithm to support traffic congestion prediction and avoidance. The experimental results proves that connected cars information can be used to predict and optimize traffic flow in a city.
如今,城市交通拥堵是司机面临的主要挑战之一。城市管理部门并不总是能够成功地应对这一挑战,而汽车数量的增加使情况变得更糟。导航系统除了生成起点和终点之间的路线外,还可用于预测和避免交通拥堵。本文提出了一种新的网联汽车环境下的交通信息表示方法。该策略基于路段树数据结构,并通过改进路由算法集成到工业导航系统中,以支持交通拥堵预测和避免。实验结果表明,车联网信息可以用于城市交通流的预测和优化。

A Framework for Threats Analysis Using Software-Defined Networking 基于软件定义网络的威胁分析框架
F. Moldovan, Ciprian Oprișa
The ability to analyze network threats is very important in security research. Traditional approaches, involving sandboxing technology are limited to simulating a single host, missing local network attacks. This issue is addressed by designing a threat analysis framework that uses software-defined networking for simulating arbitrary networks. The presented system offers flexibility, allowing a security researcher to define a virtual network that is able to capture malicious actions and to be restored to the initial state afterwards. Both the framework design and common usage scenarios are described. By providing this framework, we aim to ease the analysis effort in combating cyberthreats.
分析网络威胁的能力在安全研究中非常重要。涉及沙盒技术的传统方法仅限于模拟单个主机,错过了本地网络攻击。通过设计一个使用软件定义网络模拟任意网络的威胁分析框架来解决这个问题。所提出的系统提供了灵活性,允许安全研究人员定义一个能够捕获恶意行为并在之后恢复到初始状态的虚拟网络。描述了框架设计和常见的使用场景。通过提供这个框架,我们的目标是在打击网络威胁时简化分析工作。
