More and more people watch TV with a second device in the nearby. They use it for many different reasons: to play, to search for something, to interact with other people, etc. As a result, their visual attention is often turned to the second screen, especially during commercials. This scenario scares broadcasters, as they fear losing the advertisers' investment. Therefore, it is necessary to improve...
We propose a principled approach for the learning of causal conditions from actions and activities taking place in the physical environment through visual input. Causal conditions are the preconditions that must exist before a certain effect can ensue. We propose to consider diachronic and synchronic causal conditions separately for the learning of causal knowledge. Diachronic condition captures the...
Our work aims at helping teachers to monitor learners' engagement during mind mapping activities. The use of mind maps helps students to elaborate cognitive learning strategies like creating and organizing contents. To assess the quality of these mind maps, teachers need tools to understand students' choices and strategies when constructing their mind maps. We have defined in collaboration with teachers...
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...
Most of our current understanding of how programmers perform various software maintenance and evolution tasks is based on controlled studies or interviews, which are inherently limited in size, scope, and realism. Replicating controlled studies in the field can both explore the findings of these studies in wider contexts and study new factors that have not been previously encountered in the laboratory...
We propose a method for transferring an arbitrary style to only a specific object in an image. Style transfer is the process of combining the content of an image and the style of another image into a new image. Our results show that the proposed method can realize style transfer to specific object.
Visual attention models (VAMs) have proved useful in various multimedia applications such as video encoding, interface design, and user behavior prediction. However, existing VAMs are not generalizable enough to be utilized in all multimedia applications implying that in each application there exist some unique factors which drive the user attention. Application agnostic VAMs rely on video and image...
In this paper, a new method with visual saliency detection for image quality assessment (IQA) is proposed. Through the experiments in this paper, we have verified the proposed method can be effective than most others.
Social media platforms provide rich signal sets to understand the nature of social life, and sentiment analysis techniques have been developed to understand the emotional content of text from sites like Twitter and Facebook. Beyond text however, most social media platforms have images at their core, and communication of images may require quantization. Here, we develop methods and present results...
In this paper, we propose a new secret sharing method for Chinese characters based on non-negative matrix factorization (NMF). Chinese characters can be regarded as binary images, but traditional NMF is only suitable for gray-level images. Therefore, this paper proposes a modified version of NMF for dealing with Chinese characters in binary images. The modified NMF decomposes a Chinese character into...
Keeping students attentive during lectures may significantly improve learning outcomes. Traditional methods of attention estimation cannot offer a real-time feedback to the teacher. We present a technical concept of student attention monitoring during a lecture. The system utilizes a set of cameras providing tracking of the behavior of individual students in the classroom. The monitoring system is...
We consider UAV IoT aerial sensing that delivers multiple VR/AR immersive communication sessions to remote users. The UAV swarm is spatially distributed over a wide area of interest, and each UAV captures a viewpoint of the scene below it. The remote users are interested in visual immersive navigation of specific subareas/scenes of interest, reconstructed on their respective VR/AR devices from the...
Recently the quick development of virtual technology has made technology-aided learning more versified and education revolution more advanced. With visual and audio stimulation, technology-aided teaching can make student pay more attention than traditional way. Currently the way of learning idioms in elementary school is of more traditional way, which, without multiple interactions with students,...
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,...
Previous studies which explored the effects of typographic variables on Chinese text reading on small devices fixed the viewing distance from eyes to the screens. Hence, their results might not be generalized to the typographic design of Chinese texts on small devices. Therefore, the article tried to investigate the effects of Traditional Chinese character size and font style on reading performance...
The rapid-bubble-growth instability at the onset of flow boiling was studied experimentally in a single, 500 pm-diameter borosilicate glass microchannel subjected to a uniform heat flux of 41.9 kW/m2. Fluid was driven through the microchannel in an open-loop test facility by maintaining a constant pressure difference between a pressurized upstream reservoir and the ambient. Simultaneous measurement...
The focus of this research was to explore the language function and application via SCAN Model, Six Creative, and Assimilated Navigation, SCAN model, covering the six cultural metaphorical factors: TIME, SPACE, BODY, VISION, EMOTION, and SOCIALIZATION aspects. The SCAN model was employed as a medium to stimulate the participants to illustrate their perspectives regarding the issues of language function...
The driving system is gradually improving with the development of technology, especially for the passive safety system. However, according to the statistics of traffic accidents in Department of statistics, Ministry of Transportation and Communications R.O.C. (MOTC), there are 274,042 traffic accidents in average in the past five years. Among them, the total amount of accidents in category A1 has...
In this paper, we addressed in social network visualization for people's interest in music. This visualization system designed for interest in music on social networks provides several capabilities: (A) visualization for friends who share the same interest in music, (B) to group people who share the same interest in music into categories, and (C) to recommend songs function for an increase in the...
