"Wayfinding system" is an interdisciplinary research between the environment design and human interface of information system. The design of EXIT is to efficiently help people to identify the emergency exit when the accident occurred. In this paper, eye tracking techniques are utilized to aided EXIT design in the wayfinding system. The mobile eye tracking was used to collect the human eye...
A method is put forward to extract feature points in the indoor ceiling corner as natural landmarks by using binocular visual system and to go further to achieve absolute localization for robot. Firstly, this method puts forward a kind of double threshold Features from Accelerated Segment Test (FAST) - Scale Invariant Feature Transform (SIFT) matching algorithm, in which FAST algorithm is applied...
Using knowledge mapping tools (CiteSpace), we conducted the visualization analysis on both of international and domestic literatures in relation to ecological assets/values from the Web of Science (WoS) databases and China National Knowledge Infrastructure (CNKI) databases. By combination of the statistical data and visualization mapping, we studied on the research relationship networks and status...
This paper presents a new quantitative evaluation metric called the saturated pixel detection analysis (SPDA) to evaluate the effectiveness of color correction algorithms widely used to address the color constancy problem. Unlike most existing evaluation metrics, an innovative approach is introduced into the proposed SPDA analysis to identify the undesirable saturated image pixels. This is achieved...
Binocular disparity is of vital importance in stereoscopic vision. It determines the depth magnitude and effects the impression formation when human watch three-dimensional things. However so far how binocular disparity activates the brain regions hasn't got consistent conclusions. So a fMRI(functional magnetic resonance imaging) experiment was designed to locate cortex areas related with stereoscopic...
No-reference image quality assessment (NR IQA) has wide applicability to many problems. This paper focuses on the mechanism of divisive normalization transform (DNT) which simulates the behavior of visual cortex neurons to extract the independent components of natural images, analyzes the difference between the statistics of neighboring DNT coefficients of the images of a variety of distortion, and...
This paper proposes a content-adaptive blending method, smart compositing, for displaying two overlapped video frames on the same screen while preserving the readability of both. A pixel-wise adaptive blending factor map is generated according to the edge and saturation information of the content of only the overlay frame. Using this blending factor map, regions of the overlay frame with edges or...
A number of researches have explored the effect of embodied pedagogical agents in multimedia learning environments. Embodied pedagogical agents have been regarded as practical and powerful tools for instructions in these researches. However, it is hard to find a development kits that support the instructor or teacher to create interactive learning applications together with animated pedagogical agents...
There has been an increased demand for 3G cell phones that support multiple bands of operation and are backward compatible with the 2G/2.5G standard to provide coverage where 3G networks have not yet been fully deployed. The transceiver design for such a handset becomes complicated with the need for separate transceivers for 3G and 2G/2.5G or for multiple inter-stage receive / transmit SAW filters...
In recent years, the researches of human-agent interaction additionally provide scripting or markup languages for controlling characters' facial and bodily gesture, emotion, animation, and speech. The language's users were mainly programmers or animators. Therefore, those scripting languages not only lacked for controlling the whole plot flow, but also couldn't be used by general users. In this paper,...
