With the development of remote sensing image applications, sparse-based representation classification approaches have been investigated for better classification accuracy. This paper introduces an improved classification method based on sparse representation by representing the test samples through a dictionary. The key components of our proposed method(More)
In this paper, we present an application that dance and music using Microsoft Kinect sensor and use MIDI technology to make a visual instrument for somebody who interested in music. The program will draw a sphere in three dimensions space by OpenGL and a user can dance in the visual sphere. The user can trigger events by entering two hands or feet in a(More)
There are many problems in the present research of teaching and application of E-Learning, such as theories separated, theoretical basis indistinct, technique used indiscriminately, lack of interaction, knowledge extension short and reflection insufficient, etc. So the ideal effect of knowledge extension, based on modern instructional theories, could not be(More)
In the present there are many problems in the research of teaching and the application of E-Learning, like theories separated, theoretical basis indefinite, techniques used indiscriminately, interaction lacked, extension of the knowledge and dialectical thoughts insufficient etc. Therefore the ideal effect of knowledge extension could not be reached based(More)
Research in the field of Human-Computer Interaction (HCI) has become more and more frequently in our life. These related applications not only make our lives more convenient and efficiency, but also reduce the overhead costs. Users can more naturally, quickly and intuitively convey commands through different types of HCI applications to computer. Leap(More)
As the particularity of the mangrove ecosystem, it is difficult to do field investigation, which consumes much time, and the obtained data is not real-time. The technology of satellite remote sensing plays an important role in the detection of the ecological system. Some methods, such as band combination, expert classification and fuzzy classification, have(More)
Edge detection is widely used to extract and analyze contour and texture feature. This paper focuses on researches of wavelet analysis and the application of its improved method in edge detection. The basic idea of the improved method is that we first preprocess image, and the image texture will be shown when processing it under a uniform threshold, then(More)
This article expounds the working principle and the merits of performance of the library computer room intelligent high heat transfer heat exchanger, analyses the running effects of the heat exchanger in place of the air-conditioner of the library computer room, Analysis showed that the use of the heat exchanger can reduce the working hours of the original(More)
Metabolic flux estimation through 13C trace experiment is crucial for metabolic system to quantify the intracellular metabolic fluxes. In essence, it corresponds to a constrained optimization problem, objective function of which is non-linear and non-differentiable and exist multiple local minima making this problem a special difficulty. In this paper, we(More)
