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)
Based on needs analysis of University Teacher's files management system, this paper proposed the construction content, goals and function set. It used the Visual Studio 2005 development platform, C # Programming Language, SQL Server 2005 database management system. In the design process, it applied modular management, iterative development, and realized 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)
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)
With the development of remote sensing image applications, remote sensing imagery is an important technology to make a dynamic detection for changes of lands or coastal zones. Though high resolution remote sensing imagery provides very good performance and large information for the spatial structure variation, the limitation of its spatial structure makes(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)
Digital watermarking technology is an effective measure for copyright protection. This paper presents the design of a Flash digital watermarking application which is implemented using the Graphic User Interface (GUI) function of the MATLAB software. The application can open and play Flash animations as carriers, it can embed watermark images into the(More)
