    Image and Video Forensics

    Get PDF
    Nowadays, images and videos have become the main modalities of information being exchanged in everyday life, and their pervasiveness has led the image forensics community to question their reliability, integrity, confidentiality, and security. Multimedia contents are generated in many different ways through the use of consumer electronics and high-quality digital imaging devices, such as smartphones, digital cameras, tablets, and wearable and IoT devices. The ever-increasing convenience of image acquisition has facilitated instant distribution and sharing of digital images on digital social platforms, determining a great amount of exchange data. Moreover, the pervasiveness of powerful image editing tools has allowed the manipulation of digital images for malicious or criminal ends, up to the creation of synthesized images and videos with the use of deep learning techniques. In response to these threats, the multimedia forensics community has produced major research efforts regarding the identification of the source and the detection of manipulation. In all cases (e.g., forensic investigations, fake news debunking, information warfare, and cyberattacks) where images and videos serve as critical evidence, forensic technologies that help to determine the origin, authenticity, and integrity of multimedia content can become essential tools. This book aims to collect a diverse and complementary set of articles that demonstrate new developments and applications in image and video forensics to tackle new and serious challenges to ensure media authenticity

    Roadmap on Label-Free Super-resolution Imaging

    Get PDF
    Label-free super-resolution (LFSR) imaging relies on light-scattering processes in nanoscale objects without a need for fluorescent (FL) staining required in super-resolved FL microscopy. The objectives of this Roadmap are to present a comprehensive vision of the developments, the state-of-the-art in this field, and to discuss the resolution boundaries and hurdles that need to be overcome to break the classical diffraction limit of the label-free imaging. The scope of this Roadmap spans from the advanced interference detection techniques, where the diffraction-limited lateral resolution is combined with unsurpassed axial and temporal resolution, to techniques with true lateral super-resolution capability that are based on understanding resolution as an information science problem, on using novel structured illumination, near-field scanning, and nonlinear optics approaches, and on designing superlenses based on nanoplasmonics, metamaterials, transformation optics, and microsphere-assisted approaches. To this end, this Roadmap brings under the same umbrella researchers from the physics and biomedical optics communities in which such studies have often been developing separately. The ultimate intent of this paper is to create a vision for the current and future developments of LFSR imaging based on its physical mechanisms and to create a great opening for the series of articles in this field.Peer reviewe

    An Empirical Investigation Of Information Technology Mediated Customer Services In China

    Get PDF
    Information technology mediated customer service is a reality of the 21st century. More and more companies have moved their customer services from in store and in person to online through computer or mobile devices. Using 208 respondents collected from two Chinese universities, this paper investigates customer preference over two service delivery model (either in store or online) on five type of purchasing (retail, eating-out, banking, travel and entertainment) and their perception difference in customer service quality between those two delivery model. Results show that a majority of Chinese students prefer in store and in person for eating out. For ordering tickets for travel and entertainment, they prefer computer/mobile device. For retail purchasing and banking, less than half of the students prefer in person services. In general, the results show that ordering through computer/mobile devices has become more popular in China and has received higher rating for most of customer service quality except security compared to ordering in store. In addition, it is found that there exist a gender difference in purchasing preference and perception in service delivery quality in China

    Postsecondary peer cooperative learning programs: Annotated bibliography 2018

    Get PDF
    This 2018 annotated bibliography reviews seven postsecondary peer cooperative learning programs that have been implemented nationally and internationally to increase student achievement. An extensive literature search was conducted of published journal articles, newspaper accounts, book chapters, books, ERIC documents, thesis and dissertations, online documents, and unpublished reports. Peer learning programs in this bibliography meet the following characteristics: (a) program must have been implemented at the postsecondary or tertiary level, (b) program has a clear set of systematic procedures for its implementation at an institution, (c) program evaluation studies have been conducted and are available for review, (d) program intentionally embeds learning strategy practice along with a review of the academic content material, (e) program outcomes include both increased content knowledge with higher persistence rates, and (f) program has been replicated at another institution with similar positive student outcomes. From a review of the professional literature, nearly 1,500 citations emerged concerning seven programs that met the previously mentioned selection criteria: "Accelerated Learning Groups" (ALGs), "Emerging Scholars Program" (ESP), "Peer-Assisted Learning" (PAL), "Peer-Led Team Learning" (PLTL), "Structured Learning Assistance" (SLA), "Supplemental Instruction" (SI), and "Video-based Supplemental Instruction" (VSI). Nearly one fourth of the entries in this bibliography are from authors and researchers outside of United States. Guidance is provided to implement best practices of peer learning programs that can improve academic achievement, persistence to graduation, and professional growth of participants and facilitators of these student-led groups. The literature reports not only positive outcomes for the student participants of such programs, but includes outcomes for the student peer leaders of these academic support programs such as skill improvement with leadership, public speaking, and other employment skills along with an impact of their future vocational choices including a career in teaching at the secondary or postsecondary level. Educators need to investigate these peer learning programs to discover effective learning practices that can be adapted and adopted for use in supporting higher student achievement for students of diverse backgrounds.

    Malaysian bilateral trade relations and economic growth

    Get PDF
    This paper examines the structure and trends of Malaysian bilateral exports and imports and then investigates whether these bilateral exports and imports have caused Malaysian economic growth. Although the structure of Malaysia’s trade has changed quite significantly over the last three decades, the direction of Malaysia’s trade remains generally the same. Broadly, ASEAN, the EU, East Asia, the US and Japan continue to be the Malaysia’s major trading partners. The Granger causality tests have shown that it is the bilateral imports that have caused economic growth in Malaysia rather than the bilateral exports

    Exchange rate misalignments in ASEAN-5 countries

    The purpose of this paper is to estimate the exchange rate misalignments for Indonesia, Malaysia, Philippines, Singapore and Thailand before the currency crisis. By employing the sticky-price monetary exchange rate model in the environment of vector error-correction, the results indicate that the Indonesia rupiah, Malaysian ringgit, Philippines peso and Singapore dollar were overvalued before the currency crisis while Thai baht was undervalued on the eve of the crisis. However, they suffered modest misalignment. Therefore, little evidence of exchange misalignment is found to exist in 1997:2. In particular, Indonesia rupiah, Malaysia ringgit, Philippines peso and Singapore dollar were only overvalued about 1 to 4 percent against US dollar while the Thai baht was only 2 percent undervalued against US dollar
