In process of 3D image reconstruction, the local image breakage or mismatch are appeared when the objects have high reflection and uniform color properties, such as, windshield of car, reflective paint, etc. In this study, the above-mentioned conditions are overcame by introducing the different statement of software processing to examine the 3D model reconstruction of car. Four types processes, extract...
Human action recognition has been an active research topic for its wide application. Most researches focus on the recognition based on one single modality sensor. In this paper, we present a novel approach for human action recognition, which is based on fusing triaxial acceleration signals and depth maps. We extract Fast Fourier Transform (FFT) coefficients from acceleration signals and Histograms...
Using fish behavior to reflect changes of water quality and aim at water quality warning is currently a popular topic of environmental monitoring. The fish tracking technology with occlusion is the basis for the analysis of fish school behavior, and only tracking each individual fish accurately in the shoal can get the exact quantitative analysis of their feature. In this paper, we design the data...
In this paper, we proposed the computer vision and behavior imaging science and technology into the field of treatment of children with special needs, aiming to use computer algorithms to automatically analyze children's gaze, and further investigate children's behavior patterns and distinguish whether children are with autism characteristics in our CSBS video. We perform a series of image processing...
With growing number of high quality 3D models published online, the technique of generating efficient and economical 3D model previews has raised increasing concerns. Although several previous work has been done on the preview of static mesh, that of animated mesh is different and more complex due to the difficulty in describing the animation. In this paper, we present a novel method of automatic...
This paper investigates the construction and control of a robot arm which mimics human arm's pitching motion. In order for the robot to have the vision capability, like a human pitcher, a CCD webcam is added to capture target image. After image processing and analysis, controller can compute and then issue the motion commands to the robot arm motors. The vision system helps promote system's intelligence...
Existing dual image deblurring methods usually model blurred image pairs being taken from exactly the same viewpoint and restore a single clear image. This imposes a strong assumption that the latent clear images of both images must be completely identical. In contrast to this restricted scenario, we assume that the restored pair are different, but can be approximated by image warping due to small...
Hand gesture recognition (HGR) is an important research topic because some situations require silent communication with sign languages. Computational HGR systems assist silent communication, and help people learn a sign language. In this article, a novel method for contact-less HGR using Microsoft Kinect for Xbox is described, and a real-time HGR system is implemented. The system is able to detect...
Hand gesture has become a powerful means for human-computer interaction. Traditional gesture recognition just consider hand trajectory. For some specific applications, such as virtual reality, more natural gestures are needed, which are complex and contain movement in 3-D space. In this paper, we introduce an HMM-based method to recognize complex singlehand gestures. Gesture images are gained by a...
In this paper we present a visual processing system for bionic eye with a focus on obstacle avoidance. Bionic eye aims at restoring the sense of vision to people living with blindness and low vision. However, current hardware implant technology limits the image resolution of the electrical stimulation device to be very low (e.g., 100 electrode arrays, which is approx. 12 × 9 pixels). Therefore, we...
Current markerless 3D registration methods usually utilize a single specified category of natural features. However, the richness of various natural features is ignored. They cannot meet users' diversified registration requirements. This article proposes an integration strategy of 3D registration methods based on multiple natural features. Utilizing feature detection and tracking and 3D registration...
This paper presents a real-time video stabilization method based on motion compensation for adjusting unstable frames captured by a vibrating camera. The basic strategy is first to check if the frame is vibrant and then to analyze the vibration type and calculate the vibration degree for compensating the vibration area. Based on block motion estimation, a feature block selected from nine fixed observation...
