Male Wistar rats were given purified diets containing safflower (SAF), perilla (PER), or palm (PAL) oils with or without 1% tea polyphenols (TP) for 3 weeks, and chemical mediator releasing activity from rat peritoneal exudate cells (PEC) was measured. Histamine releasing activity was not influenced by TP, while histamine release and intracellular histamine(More)
Human interaction is one of the most important characteristics of group social dynamics in meetings. In this paper, we propose an approach for capture, recognition, and visualization of human interactions. Unlike physical interactions (e.g., turn-taking and addressing), the human interactions considered here are incorporated with semantics, i.e., user(More)
In this paper, we describe the enabling technologies to develop a smart meeting system based on a three layered generic model. From physical level to semantic level, it consists of meeting capturing, meeting recognition, and semantic processing. Based on the overview of underlying technologies and existing work, we propose a novel real-world smart meeting(More)
This paper presents a semi-automatic indexing method for “QUEVICO” — A QA model for video-based interactive media. We first provide an overview of QUEVICO, and then discuss which indices are acquired from the scenario and which must be acquired by manual or automated processing. To obtain these indices, we implemented a prototype system whose processes(More)
In this paper, we propose a novel framework "Virtual Assistant" for enhancing content potentially procured by ambient media. The Virtual Assistant is an artificial agent simulating a human assistant shown in TV programs and prompts users to provide feedback by asking questions or back-channeling. This framework ensures that sufficient information is(More)
Fecal and blood samples of infants with autism spectrum disorders (ASD) and healthy infants were analyzed to investigate the association of altered gut microbiota and ASD development. 16S rRNA gene-based sequencing found that, unlike those of healthy infants, feces of ASD infants had significantly higher and lower abundance of genera Faecalibacterium and(More)
We propose a novel framework for automated video capturing and production for desktop manipulations. We focus on the system’s ability to select relevant views by recognizing types of human behavior. Using this function, the obtained videos direct the audience’s attention to the relevant portions of the video and enable more effective communication. We first(More)
We propose a novel method for detecting hands and hand-held objects in desktop manipulation situations. In order to achieve robust tracking under few constraints, we use multiple image sensors, that is, a RGB camera, a stereo camera, and an IR camera. By using these sensors, our system realized robust tracking without the prior knowledge of an object even(More)
In this paper, we introduce an intelligent system for video recording. First, we categorized targets and purposes of shooting, and discuss the cameraworks appropriate for them. Then, we propose camera control algorithms to realize such cameraworks. Based on this idea, we built a prototype pan-tilt camera control system, in which multiple cameras with(More)
We propose a simple and robust method for detecting hands and hand-held objects involved in desktop manipulation and its use for indexing the videos. In order to achieve robust tracking with few constraints, we use multiple image sensors, that is, a RGB camera, a stereo camera, and an infrared (IR) camera. By integrating these sensors, our system realized(More)
