—In this paper, we analyze an improved DOG filter with different parameters in horizontal and vertical directions and the improved filter uses oval recognition domain instead of round recognition domain of classic DOG filter. The improved filter is used to compare with major illumination pretreatment methods. The experiment result shows the improved method(More)
This paper presents an experiment conducted in a large-screen immersive virtual environment to evaluate how texting pedestrians respond to permissive traffic alerts delivered via their cell phone. We developed a cell phone app that delivered information to texting pedestrians about when traffic conditions permit safe crossing. We compared gap selection and(More)
The paper presents an effective method for different-structure digital system based on on-line evolution with fault-tolerance technology. Integer-coding multistage evolution is used to design digital system and different-structure system is evaluated by using the knowledge of quad tree. Thus, the length of chromosome can be reduced and the degree of(More)
Surface of quartz fiber Bragg grating (QFBG) was metalized by means of electroless plating method. Two different encapsulation processes were proposed. Temperature and strain sensing properties were studied based on two different encapsulation of the QFBG. The results indicate that linearity and repeatability of the center wavelength of the QFBG sensor(More)
We investigated how people jointly coordinate their decisions and actions with a computer-generated character (agent) in a large-screen virtual environment. The task for participants was to physically cross a steady stream of traffic on a virtual road without getting hit by a car. Participants performed this task with another person or with a(More)
