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)
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 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)
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)
This article proposes a new framework using singular value decomposition based on existing methods for detecting shot boundaries in video sequences. The experimental results show that this algorithm and framework are efficient because sharp cuts are detected precisely and transition cuts are detected efficiently.
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)
In this paper, we propose an improved median filtering algorithm by adding filtration function before replacing the value of the median position with the median and doing multiple processing of median filtering to overcome the shortcoming of the traditional Median Filtering Algorithm. Experimental results are shown that an image after processed by the(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)
