BackgroundButantan–Dengue Vaccine (Butantan-DV) is an investigational, single-dose, live, attenuated, tetravalent vaccine against dengue disease, but data on its overall efficacy are needed.MethodsIn ongoing phase 3, double-blind trial in Brazil, we randomly assigned participants to receive Butantan-DV or placebo, with stratification according age (2 6 years, 7 17 and 18 59 years); 5 years of follow-up planned. The objectives the were evaluate symptomatic, virologically confirmed any...
This paper presents Rich360, a novel system for creating and viewing 360° panoramic video obtained from multiple cameras placed on structured rig. Rich360 provides an as-rich-as-possible experience by effectively resolving two issues that occur in the existing pipeline. First, deformable spherical projection surface is utilized to minimize parallax cameras. The deformed spatio-temporally according depth constraints estimated overlapping regions. enables fast efficient parallax-free stitching...
Streamers and celebrities are increasingly using virtual avatars as a form of online entertainment; moreover, VTubers concerts reporting increasing viewership. Therefore, understanding the unique characteristics, phenomena, challenges is an active topic in HCI community. We extensively investigated VTuber's concert that was streamed on various viewing platforms which fans participated voluntary creators. surveyed 1,795 audience members interviewed 10 creators to understand their experiences...
We propose a real-time convolutional neural network (CNN) training and compression method for delivering high-quality live video even in poor environment. The server delivers low-resolution segment along with the corresponding CNN super resolution (SR), after which client applies to order recover high-resolution frames. To generate trained real-time, our rapidly increases accuracy by promoting overfitting property of while also using curriculum-based training. In addition, assuming that...
With the popularity of immersive display systems that fill viewer’s field view (FOV) entirely, demand for wide FOV content has increased. A video extrapolation technique based on reuse existing videos is one most efficient ways to produce content. Extrapolating a poses great challenge, however, due insufficient amount cues and information can be leveraged estimation extended region. This article introduces novel framework allows an input consequently converts conventional into with FOV. The...
With the recent advancements in multimedia and computer graphics technology, virtual avatar concerts have become increasingly popular among both well-known celebrities subculture-based YouTubers, attracting large audiences. Although this new form of performance art can be delivered through various platforms that use different viewing formats, research on components enjoying their effects audience experience is lacking. This study aims to explore formats song genres sickness, presence,...
Recently, artists and fans meet more often online owing to the COVID-19 pandemic. Therefore, need engage closely with enjoy rich content. FlumeRide is a mobile application that helps greet through video calls. Beyond simply connecting two, it provides detailed features similar experience in face-to-face meetings. We first investigated overall contexts challenges faced by during meet-and-greets derived design elements. Then, we designed implemented system supports various communications...
A low-end embedded platform for Internet of Things (IoT) often suffers from a critical trade-off dilemma between security enhancement and computation overhead. We propose PUFSec, new device fingerprint-based architecture IoT devices. By leveraging intrinsic hardware characteristics, we aim to design computationally lightweight software system so that complex cryptography can dramatically be prohibited. exploit the innovative idea Public Physical Unclonable Functions (PPUFs) fundamentally...
PicMe is a mobile application that provides interactive on-screen guidance helps the user take pictures of composition another person requires. Once requester captures picture desired and delivers it to (photographer), 2.5D system, called virtual frame, guides in real-time by showing three-dimensional target image (i.e., size shape). In addition, according matching accuracy rate, we provide small-sized an inset window as feedback edge visualization for further alignment detail elements. We...
Owing to the COVID-19 pandemic, concerts are gradually being held online. Beyond live-streaming, it has recently become popular utilize various realistic video technologies add entertainment value and immersion online concerts. We conducted a multi-view layout design study in virtual reality environment with head-mounted display help users effectively explore immerse themselves multiple videos from angles. Based on an analysis of existing user interface for navigation characteristics...
Cushing's syndrome is characterized by central obesity, fatigability, weakness, amenorrhea, hirsutism, edema, hypertension, impaired glucose tolerance, and osteoporosis due to excessive production of steroids. an important cause secondary osteoporosis. Patients with have a high incidence osteoporotic fractures. At least, 30-50% patients experience fractures, particularly in the vertebral body. And it consistent 50% prevalence syndrome. However, reports multiple pathological fractures young...
High-quality depth painting for each object in a scene is challenging task 2D to 3D stereo conversion. One way accurately estimate the varying within an image utilize existing models. Automatic pose estimation approaches based on 2D-3D feature correspondences have been proposed obtain from given model. However, when model not identical target object, previous methods often produce erroneous vicinity of silhouette object. This paper introduces novel model-based method that effectively...
We present a hybrid approach that segments an object by using both color and depth information obtained from views captured low-cost RGBD camera sparsely-located cameras. Our system begins with generating dense of each target image Structure Motion Joint Bilateral Upsampling. formulate the multi-view segmentation as Markov Random Field energy optimization on graph constructed superpixels. To ensure inter-view consistency results between images have too few features, our local mapping method...
Due to the recent COVID-19 pandemic, many performances have been conducted using computer-medicated communication technologies. Many took form of online concerts that utilize live streaming Some artists held virtual avatar on reality platforms provide a higher level immersion and various scenes effects. Conventional typically require performers wear motion capture equipment track their movements fly, limiting performers’ choice outfits making it challenging simultaneously perform in single...
This paper introduces ScreenX, which is a novel movie viewing platform that enables ordinary theatres to become multi-projection theatres. the general public enjoy immersive experiences. The left and right side walls are used form surrounding screens. display environment delivers strong sense of immersion in viewing. However, naïve content on results appearance distorted images according location viewer. In addition, different dimensions width, height, depth among may lead Therefore, for...
We present a new interactive playback method to enhance 360° viewing experiences. Our automatically rotates the virtual camera of panoramic video (360° video) player during guide viewer through most important regions video. With this method, can watch with minimum efforts find events in scene both (e.g., HMD) and less-interactive PC TV) environments. To estimate importance each direction, we combine spatial temporal saliency cluster-based weighting. A maximum backward cumulative volume...
Recently, various virtual avatar music content that showcases singing and dancing have been produced, as artists gain popularity, offline concerts also emerged. However, there are few examples of band where avatars play instruments. In addition, using large screens at the front limited in their ability to utilize fantastical effects high degree freedom unique reality. this paper, inspired by these limitations content, we introduce production case immersive interactive concert idol Verse
