Open-source technologies (OSINT) and Social Media Intelligence (SOCMINT) are becoming increasingly popular with investigative and government agencies, intelligence services, media companies, and corporations. These OSINT and SOCMINT technologies use sophisticated techniques and special tools to efficiently analyze the continually growing sources of information. There is a great need for training and further education in the OSINT field worldwide. This report describes the importance of open source or social media intelligence for evaluating disaster management. It also gives an overview of the government work in Australia, Haiti, and Japan for disaster management using various OSINT tools and platforms. Thus, decision support for using OSINT and SOCMINT tools is given, and the necessary training needs for investigators can be better estimated.

During these past years, international COVID data have been collected by several reputable organizations and made available to the worldwide community. This has resulted in a wellspring of different visualizations. Many different measures can be selected (e.g., cases, deaths, hospitalizations). And for each measure, designers and policy makers can make a myriad of different choices of how to represent the data. Data from individual countries may be presented on linear or log scales, daily, weekly, or cumulative, alone or in the context of other countries, scaled to a common grid, or scaled to their own range, raw or per capita, etc. It is well known that the data representation can influence the interpretation of data. But, what visual features in these different representations affect our judgments? To explore this idea, we conducted an experiment where we asked participants to look at time-series data plots and assess how safe they would feel if they were traveling to one of the countries represented, and how confident they are of their judgment. Observers rated 48 visualizations of the same data, rendered differently along 6 controlled dimensions. Our initial results provide insight into how characteristics of the visual representation affect human judgments of time series data. We also discuss how these results could impact how public policy and news organizations choose to represent data to the public.
在过去几年中,几个知名组织收集了国际COVID数据并向国际社会提供。这导致了不同可视化的源泉。可以选择许多不同的措施(例如,病例、死亡、住院)。对于每一项测量,设计者和政策制定者可以对如何表示数据做出无数不同的选择。来自个别国家的数据可以以线性或对数比例尺、每日、每周或累积、单独或在其他国家的背景下、按比例缩放到共同网格或按比例缩放到自己的范围、原始或人均等。众所周知,数据表示会影响数据的解释。但是,这些不同表征中的哪些视觉特征会影响我们的判断呢?为了探索这个想法,我们进行了一个实验,我们要求参与者查看时间序列数据图,并评估如果他们去其中一个所代表的国家旅行,他们会有多安全,以及他们对自己的判断有多自信。观察者对相同数据的48种可视化方式进行了评级,这些可视化方式在6个受控维度上呈现出不同的效果。我们的初步结果为视觉表征的特征如何影响人类对时间序列数据的判断提供了见解。我们还讨论了这些结果如何影响公共政策和新闻机构如何选择向公众展示数据。

Conditional synthetic food image generation 条件合成食品图像生成
Pub Date : 2023-01-16 DOI: 10.2352/ei.2023.35.7.image-268

Generative Adversarial Networks (GAN) have been widely investigated for image synthesis based on their powerful representation learning ability. In this work, we explore the StyleGAN and its application of synthetic food image generation. Despite the impressive performance of GAN for natural image generation, food images suffer from high intra-class diversity and inter-class similarity, resulting in overfitting and visual artifacts for synthetic images. Therefore, we aim to explore the capability and improve the performance of GAN methods for food image generation. Specifically, we first choose StyleGAN3 as the baseline method to generate synthetic food images and analyze the performance. Then, we identify two issues that can cause performance degradation on food images during the training phase: (1) inter-class feature entanglement during multi-food classes training and (2) loss of high-resolution detail during image downsampling. To address both issues, we propose to train one food category at a time to avoid feature entanglement and leverage image patches cropped from high-resolution datasets to retain fine details. We evaluate our method on the Food-101 dataset and show improved quality of generated synthetic food images compared with the baseline. Finally, we demonstrate the great potential of improving the performance of downstream tasks, such as food image classification by including high-quality synthetic training samples in the data augmentation.
生成对抗网络(GAN)由于其强大的表征学习能力在图像合成领域得到了广泛的研究。在这项工作中,我们探索了StyleGAN及其在合成食品图像生成中的应用。尽管GAN在自然图像生成方面的表现令人印象深刻,但食物图像存在高度的类内多样性和类间相似性,导致合成图像的过拟合和视觉伪像。因此,我们的目标是探索GAN方法在食物图像生成方面的能力并提高其性能。具体而言,我们首先选择StyleGAN3作为基线方法生成合成食品图像并分析其性能。然后,我们确定了在训练阶段可能导致食物图像性能下降的两个问题:(1)多食物类训练期间的类间特征纠缠;(2)图像下采样期间高分辨率细节的损失。为了解决这两个问题,我们建议一次训练一个食物类别,以避免特征纠缠,并利用从高分辨率数据集裁剪的图像补丁来保留细节。我们在food -101数据集上评估了我们的方法,并显示与基线相比,生成的合成食品图像的质量有所提高。最后,我们展示了通过在数据增强中加入高质量的合成训练样本来提高下游任务(如食品图像分类)性能的巨大潜力。

The method of loci (memory palace technique) is a learning strategy that uses visualizations of spatial environments to enhance memory. One particularly popular use of the method of loci is for language learning, in which the method can help long-term memory of vocabulary by allowing users to associate location and other spatial information with particular words/concepts, thus making use of spatial memory to assist memory typically associated with language. Augmented reality (AR) and virtual reality (VR) have been shown to potentially provide even better memory enhancement due to their superior visualization abilities. However, a direct comparison of the two techniques in terms of language-learning enhancement has not yet been investigated. In this presentation, we present the results of a study designed to compare AR and VR when using the method of loci for learning vocabulary from a second language.
记忆宫殿法(loci method of memory palace technique)是一种利用空间环境的可视化来增强记忆的学习策略。位点法的一个特别流行的用途是语言学习,其中该方法可以通过允许用户将位置和其他空间信息与特定的单词/概念联系起来,从而利用空间记忆来辅助通常与语言相关的记忆,从而帮助词汇的长期记忆。增强现实(AR)和虚拟现实(VR)已经被证明有可能提供更好的记忆增强,因为它们具有卓越的可视化能力。然而,两种技术在语言学习增强方面的直接比较尚未被调查。在本次演讲中,我们介绍了一项研究的结果,该研究旨在比较AR和VR在使用loci方法学习第二语言词汇时的效果。

Color Imaging XXVIII: Displaying, Processing, Hardcopy, and Applications Conference Overview and Papers Program 彩色成像XXVIII:显示,处理,硬拷贝和应用会议概述和论文计划
Pub Date : 2023-01-16 DOI: 10.2352/ei.2023.35.15.color-a15
Abstract Color imaging has historically been treated as a phenomenon sufficiently described by three independent parameters. Recent advances in computational resources and in the understanding of the human aspects are leading to new approaches that extend the purely metrological view of color towards a perceptual approach describing the appearance of objects, documents and displays. Part of this perceptual view is the incorporation of spatial aspects, adaptive color processing based on image content, and the automation of color tasks, to name a few. This dynamic nature applies to all output modalities, including hardcopy devices, but to an even larger extent to soft-copy displays with their even larger options of dynamic processing. Spatially adaptive gamut and tone mapping, dynamic contrast, and color management continue to support the unprecedented development of display hardware covering everything from mobile displays to standard monitors, and all the way to large size screens and emerging technologies. The scope of inquiry is also broadened by the desire to match not only color, but complete appearance perceived by the user. This conference provides an opportunity to present, to interact, and to learn about the most recent developments in color imaging and material appearance researches, technologies and applications. Focus of the conference is on color basic research and testing, color image input, dynamic color image output and rendering, color image automation, emphasizing color in context and color in images, and reproduction of images across local and remote devices. The conference covers also software, media, and systems related to color and material appearance. Special attention is given to applications and requirements created by and for multidisciplinary fields involving color and/or vision.
彩色成像历来被认为是一种由三个独立参数充分描述的现象。计算资源的最新进展和对人类方面的理解正在导致新的方法,将纯计量的颜色观点扩展到描述物体、文件和显示器外观的感性方法。这种感知视图的一部分是空间方面的结合,基于图像内容的自适应色彩处理,以及色彩任务的自动化,仅举几例。这种动态特性适用于所有输出模式,包括硬拷贝设备,但在更大程度上适用于具有更大动态处理选项的软拷贝显示器。空间自适应色域和色调映射、动态对比和色彩管理继续支持显示硬件的前所未有的发展,涵盖从移动显示器到标准显示器,一直到大尺寸屏幕和新兴技术。查询的范围也扩大了,不仅要匹配颜色,而且要匹配用户所感知的完整外观。本次会议提供了一个展示、互动和了解彩色成像和材料外观研究、技术和应用的最新发展的机会。会议的重点是色彩基础研究和测试、彩色图像输入、动态彩色图像输出和渲染、彩色图像自动化、强调语境中的色彩和图像中的色彩以及跨本地和远程设备的图像再现。会议还涵盖了与颜色和材料外观相关的软件、媒体和系统。特别关注由涉及色彩和/或视觉的多学科领域创建的应用和要求。

Abstract We live in a visual world. The perceived quality of images is of crucial importance in industrial, medical, and entertainment application environments. Developments in camera sensors, image processing, 3D imaging, display technology, and digital printing are enabling new or enhanced possibilities for creating and conveying visual content that informs or entertains. Wireless networks and mobile devices expand the ways to share imagery and autonomous vehicles bring image processing into new aspects of society. The power of imaging rests directly on the visual quality of the images and the performance of the systems that produce them. As the images are generally intended to be viewed by humans, a deep understanding of human visual perception is key to the effective assessment of image quality.

Media Watermarking, Security, and Forensics 2023 Conference Overview and Papers Program 媒体水印,安全和取证2023会议概述和论文计划
Pub Date : 2023-01-16 DOI: 10.2352/ei.2023.35.4.mwsf-a04
Abstract The ease of capturing, manipulating, distributing, and consuming digital media (e.g., images, audio, video, graphics, and text) has enabled new applications and brought a number of important security challenges to the forefront. These challenges have prompted significant research and development in the areas of digital watermarking, steganography, data hiding, forensics, deepfakes, media identification, biometrics, and encryption to protect owners’ rights, establish provenance and veracity of content, and to preserve privacy. Research results in these areas has been translated into new paradigms and applications for monetizing media while maintaining ownership rights, and new biometric and forensic identification techniques for novel methods for ensuring privacy. The Media Watermarking, Security, and Forensics Conference is a premier destination for disseminating high-quality, cutting-edge research in these areas. The conference provides an excellent venue for researchers and practitioners to present their innovative work as well as to keep abreast of the latest developments in watermarking, security, and forensics. Early results and fresh ideas are particularly encouraged and supported by the conference review format: only a structured abstract describing the work in progress and preliminary results is initially required and the full paper is requested just before the conference. A strong focus on how research results are applied by industry, in practice, also gives the conference its unique flavor.
数字媒体(如图像、音频、视频、图形和文本)的捕获、操作、分发和消费的便利性使新应用成为可能,同时也带来了许多重要的安全挑战。这些挑战促使了数字水印、隐写术、数据隐藏、取证、深度伪造、媒体识别、生物识别和加密等领域的重大研究和发展,以保护所有者的权利,确定内容的来源和真实性,并保护隐私。这些领域的研究成果已经转化为在保持所有权的同时将媒体货币化的新范式和应用,以及新的生物识别和法医识别技术,以确保隐私的新方法。媒体水印、安全和取证会议是传播这些领域高质量、前沿研究的首要目的地。会议为研究人员和从业者提供了一个绝佳的场所来展示他们的创新工作,并与水印,安全和取证的最新发展保持同步。会议审查格式特别鼓励和支持早期成果和新想法:最初只需要一份描述正在进行的工作和初步结果的结构化摘要,并要求在会议前提交全文。对研究成果如何在行业中应用的强烈关注也使会议具有独特的风格。

These challenges have prompted significant research and development in the areas of digital watermarking, steganography, data hiding, forensics, deepfakes, media identification, biometrics, and encryption to protect owners’ rights, establish provenance and veracity of content, and to preserve privacy. Research results in these areas has been translated into new paradigms and applications for monetizing media while maintaining ownership rights, and new biometric and forensic identification techniques for novel methods for ensuring privacy. The Media Watermarking, Security, and Forensics Conference is a premier destination for disseminating high-quality, cutting-edge research in these areas. The conference provides an excellent venue for researchers and practitioners to present their innovative work as well as to keep abreast of the latest developments in watermarking, security, and forensics.
