This paper indicates the dataset and challenges evaluated under PETS2017. In this edition PETS continues the evaluation theme of on-board surveillance systems for protection of mobile critical assets as set in PETS 2016. The datasets include (1) the ARENA Dataset; an RGB camera dataset, as used for PETS2014 to PETS 2016, which addresses protection of trucks; and (2) the IPATCH Dataset; a multi sensor...
Mobile devices can cause visual discomfort and even injuries to the eyes owing to shaking and vibration. In this study, we aim to develop a real-time visual tracking technique for mobile display stabilization in order to provide users with a comfortable interaction experience and reduce the hurt caused by screen vibration. The workflow of this mechanism includes tracking the motion of the mobile device,...
This paper proposes a multi-lingual enhanced Rapid Serial Visual Presentation (RSVP) system named “MulLinR,” which is an attempt for language-specific problems of existing RSVP tools. We design and build a prototype system, which currently only supports Japanese, and experiment with variation of presentation time intervals. Experimental results suggests 400 milliseconds is the most suitable time interval...
We present a long-term intrinsically motivated structure learning method for modeling transition dynamics during controlled interactions between a robot and semipermanent structures in the world. These structures serve as the basis for a number of possible future tasks defined as Markov Decision Processes (MDPs). We apply a structure learning technique to a multimodal affordance representation that...
In this paper, the authors report the initial development stages of Jeliot Mobile, a tool that aims to bring the benefits of visualization to the new generation of learners that makes use of new technologies. From the research point of view the authors want to 1) frame the development of the tool in the socio-constructivist paradigm, and 2) bring the learner-centeredness via participatory design....
This paper introduces the framework of mobile Computer Music interfaces within the context of Human Computer Interaction (HCI). It examines the unique problems posed by the use of computers by composers and performers of music. It emphasizes on the new various interfacing protocols, metaphors and paradigms that apply HCI design methodologies on the world of music, producing special modules like: performance...
This work aims to explore the benefits and potential uses of Augmented Reality technology for supporting communication in lectures and presentations. In this paper we present the architecture and implementation of an Augmented Presentation Feedback System (APFs). The system allows a speaker equipped with an Augmented Reality Head-Mounted Display to visualize visual cues depicted over the listeners'...
In this paper, we proposed intensity comparison based compact descriptor for mobile visual search. For practical mobile applications, the low complexity and the descriptor size are more preferable, and many algorithms such as SURF, CHoG, and PCA-SIFT have been proposed. However, these approaches focused on not the feature description but the extraction time and the size of the feature. This paper...
Image collections, both private and commercial, are ever growing and therefore visual information is becoming more and more important. Moreover, the classical paradigm of how pictures are typically taken has changed completely, first with the spread of digital cameras and, more recently, with mobile devices equipped with integrated cameras. Clearly, these image repositories need to be managed, and...
In recent years the diversity and the ownership of mobile devices steadily increased while the prices for this kind of devices decreased to a level that allows many students to own reasonably powerful devices. As mobile devices are also being used in learning scenarios, the challenge of today is the integration of multiple heterogeneous devices into existing and upcoming learning scenarios. This paper...
In this paper, we introduce a novel touristic trip suggestion system to facilitate the traveling of mobile users in a given city. Given the current user location and his touristic destination, our system can suggest a shortest trip path that visits as many popular landmarks as possible. To this end, we collect geographical tagged photos from Flickr [1] and Panoramio [2] photo sharing websites. Then...
We introduce MobiTOP (mobile tagging of objects and people), a map-based application which allows users to contribute and share geo-referenced multimedia annotations via mobile devices. An important feature of MobiTOP is that annotations are hierarchical, allowing annotations to be annotated to an arbitrary depth. MobiTOPpsilas interface was designed using a participatory design methodology to ensure...
This paper presents an architecture to support fast prototyping of augmented reality systems, based on virtual reality. The architecture defines simulation services separated from other aspects of the system. These services support incremental evolution of simulated prototypes into nonsimulated systems. Focus is also placed on user interaction,through the definition of an interaction architecture...
Computing technology is radically changing the manner in which we work and communicate with computers. ubiquitous virtual reality (U-VR) has been researched in order to apply the concept of virtual reality and its technology into ubiquitous computing. In this paper, we analyze past research on ubiquitous virtual reality and find future research direction.
A hierarchical classification matching scheme for fractal image compression is proposed in this paper. This scheme reduces the encoding time dramatically by partitioning the domain pools hierarchically. Experimental results on standard gray scale image show that the hierarchical classification matching scheme yields much better performance over other classification matching scheme. Compared with Fisherpsilas...
