Simple Online and Realtime Tracking with a Deep Association Metric (DeepSORT) is a method of multi-object tracking combined appearance features with motion state of objects estimated by Kalman Filter which has a promising performance. However, maintaining the identity of targets becomes formidable when the objects have a similar appearance and complex patterns of the movement. To address these issues, a novel Online Multi-object Tracking with Siamese Network and Optical Flow is proposed. We utilize the Siamese network structure to obtain our appearance feature extractor. Furthermore, optical flow is introduced into the scheme to promote the accuracy of motion prediction from the Kalman filter. Our approach combines appearance and motion features in a tracking framework. The experimental results evaluated on the public MOT dataset illustrate that our method has the better performance in comparison with the DeepSORT algorithm.
基于深度关联度量的简单在线实时跟踪(Deep sort)是一种将卡尔曼滤波估计的目标的外观特征与运动状态相结合的多目标跟踪方法,具有很好的应用前景。然而,当目标具有相似的外观和复杂的运动模式时,保持目标的身份变得非常困难。为了解决这些问题,提出了一种基于Siamese网络和光流的在线多目标跟踪方法。我们利用暹罗网络结构来获得我们的外观特征提取器。此外,该方案还引入了光流,以提高卡尔曼滤波的运动预测精度。我们的方法在跟踪框架中结合了外观和运动特征。在公共MOT数据集上的实验结果表明,与DeepSORT算法相比,我们的方法具有更好的性能。

Object detection is one of the most important and challenging branches of computer vision, which has been widely applied in our life. With the rapid development of deep learning networks for detection tasks, the performance of object detectors has been greatly improved. However, the lack of large labeled dataset obstructs the usage of convolutional neural networks (CNN) for detecting in thermal infrared images. Most existing dataset focus on visible images, while thermal infrared images are helpful for detection even in a dark environment. To address this problem, we propose the use of transfer learning to improve the accuracy of infrared pedestrian detection. We pretrain a convolutional neural network on a large dataset (which contains 1.8 million images with 654 categories), then use the convolutional neural network as a fixed feature extractor for the task of infrared pedestrian detection. The average precision of detection using ImageNet pretrained model alone is 83.34%. By adding ours pretrained model, the average precision has improved to 84.78%. We believe that the method of transfer learning can be extended to other infrared detection applications and achieve other breakthroughs.
目标检测是计算机视觉中最重要和最具挑战性的分支之一,在我们的生活中得到了广泛的应用。随着深度学习网络在检测任务中的快速发展,目标检测器的性能得到了很大的提高。然而,缺乏大型标记数据集阻碍了卷积神经网络(CNN)在热红外图像检测中的应用。大多数现有数据集中在可见光图像上,而热红外图像即使在黑暗环境下也有助于检测。为了解决这个问题,我们提出使用迁移学习来提高红外行人检测的准确性。我们在一个大型数据集(包含180万张图像和654个类别)上预训练卷积神经网络,然后使用卷积神经网络作为红外行人检测任务的固定特征提取器。单独使用ImageNet预训练模型的平均检测精度为83.34%。通过加入我们的预训练模型,平均精度提高到84.78%。我们相信迁移学习的方法可以推广到其他红外探测应用中,实现其他突破。

Retinal vessel is the only vessel structure in human circulatory system that can be directly observed by non-invasive methods. According to clinical findings, the reduction of arteriovenous width ratio (AVR) acts as an indicator to predict the risk of many systemic diseases. Therefore, it's essential to develop an automatic classification method for arteries and veins to calculate AVR. A method that combines the deep segmentation network and tracking algorithm is proposed in this paper to classify arteries and veins in retinal images. This automatic processing has three steps: (1) retinal images are preprocessed with a haze-removal technique (2) a U-net segmentation network is utilized to classify pixels into background, artery or vein (3) a tracking algorithm is applied for vessel-wise classifications. The proposed method is tested on a clinical dataset and the results present an accuracy of 93.57% for vessel-wise classifications.
视网膜血管是人体循环系统中唯一可以用无创方法直接观察到的血管结构。根据临床发现,动静脉宽度比(AVR)的降低可作为预测许多全身性疾病风险的指标。因此,有必要开发一种自动分类方法来计算动静脉的AVR。本文提出了一种结合深度分割网络和跟踪算法的视网膜图像动静脉分类方法。这种自动处理有三个步骤:(1)用去雾技术对视网膜图像进行预处理;(2)利用U-net分割网络将像素分类为背景、动脉或静脉;(3)采用跟踪算法进行血管分类。该方法在临床数据集上进行了测试,结果表明血管分类的准确率为93.57%。

Image is one of the core concerns in modern Astronomy. Telescopes capture photons emitted from sources deep inside the universe, forming images or spectrums which then be analyzed by astronomers. In the recent decades, people have built large amount of land-based and space-based telescopes which are observing light covering a wide range of wave length. The amount of the imaging data increased rapidly. For a typical integral field unit (also called the IFU) telescope, 60 GB of data is generated each night. The requirements of real time processing of these data raised challenges to astronomers. These requirements necessitate the developing of efficient computer algorithms. One important part of these requirements is the classification of galaxies. The morphologies of the galaxies can contribute in many aspects of the astronomical studies. The distribution of galaxies of different morphologies (for example ecliptic and spiral) can reflect certain large scale characteristic of the universe, such as the evolution of the galaxies, and the distribution of Hydrogen in the universe. In this work, we train a neural network and use a series of computer vision algorithms to build a Galaxy Detection and Classification Tool (GalaDC), which can detect and classify galaxies with high efficiency and accuracy. GalaDC is user friendly, supports batch processing, and is suitable for handling images which consists of multiple galaxies and do statistical analysis.
图像是现代天文学的核心问题之一。望远镜捕捉从宇宙深处发射的光子,形成图像或光谱,然后由天文学家进行分析。近几十年来,人们已经建造了大量的陆基和天基望远镜,用于观测各种波长的光。成像数据量迅速增加。对于一个典型的积分场单元(也称为IFU)望远镜,每晚产生60 GB的数据。实时处理这些数据的要求给天文学家带来了挑战。这些要求要求开发高效的计算机算法。这些要求的一个重要部分是星系的分类。星系的形态在天文学研究的许多方面都有贡献。不同形态的星系(如黄道形和螺旋形)的分布可以反映宇宙的某些大尺度特征,如星系的演化、氢在宇宙中的分布等。在这项工作中,我们训练了一个神经网络,并使用了一系列的计算机视觉算法来构建一个星系检测和分类工具(GalaDC),该工具可以高效、准确地对星系进行检测和分类。GalaDC用户友好,支持批处理,适合处理由多个星系组成的图像并进行统计分析。

As an effective image preprocessing method, color correction is widely used in the field of image stitching. However, due to the changeable visual environment, parallax often occurs in mosaic images. So far, there are few algorithms dealing with color correction under parallax situation. And most color correction methods produce poor results in images with parallax. This paper introduces a color correction algorithm which can also be applied in the case of parallax in image mosaic. We use VFC algorithm, color hue information and iterative calculation to obtain better color correction results. Compared with existing algorithms, it has the wider range of applications. The experiments show that our method has faster time efficiency and better results.
色彩校正作为一种有效的图像预处理方法,在图像拼接领域得到了广泛的应用。然而,由于视觉环境的变化,拼接图像经常出现视差。目前,处理视差情况下色彩校正的算法很少。而且大多数色彩校正方法在视差图像中产生的效果都很差。本文介绍了一种适用于图像拼接视差情况的色彩校正算法。利用VFC算法、色相信息和迭代计算得到较好的色彩校正结果。与现有算法相比,具有更广泛的应用范围。实验表明,该方法具有更快的时间效率和更好的效果。

In order to effectively improve the efficiency of multi-constrained QoS routing and reduce the energy consumption of data on the transmission path an efficient routing algorithm needs to be designed. Aiming at the problem of constrained QoS routing, an adaptive chaotic shuffled frog leaping algorithm is designed, a graph theory model of wireless image sensor network is established, and a corresponding fitness function is derived to find the path with the least energy consumption. Added new adaptive operator and chaotic operator to improve the global search ability. In the simulation, the adaptive chaotic shuffled frog leap algorithm is compared with evolutionary algorithm and particle swarm optimization. The experimental results prove that compared with evolutionary algorithm and particle swarm optimization the adaptive chaotic shuffled frog leap algorithm can be effectively accelerate convergence speed and reduce the energy loss of data on the transmission path.

Ordinary QR code does not have the function of anti duplication, and it is easy to be copied and counterfeited. In order to overcome this loophole, an anti-counterfeiting method using CMYK color printing metamerism characteristics + embedded pseudo-random noise is adopted to generate a QR code with dual anti duplication and anti-counterfeiting (secure QR code for short). Firstly, the anti-counterfeiting information is encoded and embedded into the ordinary QR code in the form of noise to generate the first-level anti-copying and anti-counterfeiting QR code with information. Then the CMYK color ratio is modulated with the second-level anti-counterfeiting information to satisfy the metamerism characteristic, and the second-level anti-counterfeiting is realized. Experimental tests show that the secure QR code designed in this paper has good information hiding performance, anti-replication performance and multi-code integration function, and can be used in anti-counterfeiting of trademarks, books, labels, etc.

At the moment when this article is written, a pandemic disease is attacking our lives, our style of living and our economy. The present work uses this occasion for focusing the attention on the importance to make available a digital copy of our knowledge, history and habits. The slower passing of time inside own residence let the individual to rediscover natural indoor activities, like reading a book or watching a documentary, and try to mentally escape by a virtual visit in a museum or a city. The first evidence coming out from these sites is mainly the limits of this technology for appreciating the artworks, even inside 3D environments, and, probably the most important, the lack of standardization in terms of accessibility and quality of the products. The present work focuses the attention only on one of the aspects of the processes for studying and documenting an artwork: the data acquisition and preprocessing data fusion. For approaching these steps, an out-of-the-market 3D technology based on the combination of several laser sources will be described: the description of this kind of systems is the pretext for analyzing the main differences with the available devices and techniques today largely used in Cultural Heritage environment, but especially for highlighting how the research can try to unify the gamification with diagnostic and restoration support in this sector.
在写这篇文章的时候,一种流行病正在袭击我们的生活、我们的生活方式和我们的经济。目前的工作利用这个机会,将注意力集中在提供我们的知识、历史和习惯的数字副本的重要性上。在自己的住所里,时间的缓慢流逝让个人重新发现自然的室内活动,比如看书或看纪录片,并试图通过虚拟参观博物馆或城市来逃避精神上的逃避。从这些网站得到的第一个证据主要是这种技术在欣赏艺术品方面的局限性,即使是在3D环境中,而且,可能最重要的是,在产品的可访问性和质量方面缺乏标准化。目前的工作只关注研究和记录艺术品过程的一个方面:数据采集和预处理数据融合。为了接近这些步骤,将描述一种基于几种激光源组合的市场外3D技术:对这种系统的描述是分析与今天主要用于文化遗产环境的可用设备和技术的主要差异的借口,但特别是为了突出研究如何尝试将游戏化与该领域的诊断和恢复支持统一起来。

Makeup, derived from the human pursuit of beauty, it changes the image of people appearance, brings more beautiful enjoyment and spiritual pleasure. However, recent studies have shown that facial makeup have a negative effect on face verification. To solve this problem, we formulate an end-to-end deep learning network which is composed of a stem CNN and a novel mapping module. Specifically, we pre-train our framework on a comprehensive dataset and fine-tune our mapping module on makeup datasets. Then we experimentally validate the proposal on these datasets. Experimental results demonstrate that the proposal achieves promising performance compared to the existing state-of-the-art methods.
化妆,源于人类对美的追求,它改变了人们的外貌形象,带来了更多美的享受和精神上的愉悦。然而,最近的研究表明,面部化妆对面部识别有负面影响。为了解决这个问题,我们构建了一个端到端的深度学习网络,该网络由一个主干CNN和一个新颖的映射模块组成。具体来说,我们在一个全面的数据集上预训练我们的框架,并在化妆数据集上微调我们的映射模块。然后在这些数据集上进行了实验验证。实验结果表明,与现有的先进方法相比,该方法具有良好的性能。
