Abstract: A vision-based user interface of a mobile robotic arm for people with severe disabilities is described in this paper. The robotic arm’s main body can be contained in a laptop computer’s briefcase without removing any parts. The user interface consists of a single web camera to obtain user’s the eye movements, computer running a detection program of the center of the iris and pupil from the captured images, and display unit to indicate feedback information to the user. Control boxes to detect user’s eye movements were also made and superimposed on the processed images. It is clear from the experimental results that an able-bodied subject can operate the proposed user interface without any difficulty, and that using it promises to support to select one of foods on a table. Keywords: Robotic arm; self-feeding system; people with severe disabilities; eye movement; image processing

Abstract: In this paper, we propose the computation model of illusion of Hellman grid image. We simulate the phenomenon that dark spots appear on intersections of the white lines by using wavelet transforms. Additionally, we reproduced the phenomenon that the dark spot disappears in attention by the computation model based on spatial frequency. In order to confirm validity of the proposed method, we show the relationship between the illusion and the spatial frequency by the qualitative experiments with subjects. Keywords: Illusion, Simulation, Hellman grid, Spatial Frequency, Wavelet Transform

Abstract: There is great pressure on population growth and water resources shortage in China. Aiming to monitor the early stage of crop growth, this paper presents a photosynthesis-based monitoring model for grain production. Not only the normalized difference vegetation index and elements such as the growing degree day are considered, the factors of sunshine and the cost of water resource are also considered in the model. Combining the meteorological data with the vegetation index that is adopted from remote sensing, the model contains the elements of solar radiation, effective air temperature, vegetation biomass, stomatal opening, water stress, and the influence of temperature on grain plants, such as low-temperature sterility and high-temperature injury. Keywords: Crop production index; Photosynthesis; Remote sensing; Monitoring; Water resource

Abstract: The desertification process to China’s capital, Beijing area, is analyzed by using the state of vegetation, soil moisture and meteorological data collected by the satellites. The growth of vegetation, soil moisture and long-term changes of temperature and precipitation in the selected two study regions that are near Beijing is analyzed and compared (from 2002 to 2011). Thus the trend of desertification can be predicted, and the effective long-term protection and control strategy can be set up. Keywords: Desertification prevention; Vegetation index; Soil moisture; Temperature and precipitation; remote sensing
