摘要：mobile platform is now widely seen as a promising multimedia service with a favorable user group and market prospect. To study the influence of mobile terminal models on the quality of scene roaming, a parameter setting platform of mobile terminal models is established to select the parameter selection and performance index on different mobile platforms in this paper. This test platform is established based on model optimality principle, analyzing the performance curve of mobile terminals in different scene models and then deducing the external parameter of model establishment. Simulation results prove that the established test platform is able to analyze the parameter and performance matching list of a mobile terminal model.

摘要：Xinjiang folk art patterns and designs are the art treasures of Chinese cultural treasure-house as well as the precious humanistic resources of Western China. In the process of collecting, sorting out and studying Xinjiang folk art patterns, the elegant simplicity as well as the good taste stands out impressively, and the pattern shape as well as the layout composition shows a distinctive national trait and a strong local color. As ＂The Geometry of Nature＂, fractal geometry brings about a new performing method. Various fractal graphs are created by different generators. Their dynamic pictures contain visual information of great magnitude and their artistic effect is similar to Xinjiang folk art patterns, which fully proves the fractal beauty in Xinjiang folk art patterns.

摘要：Fabric pattern contains many types of the available pattern elements, which not only can be used for the researchers, but also as the material for the designer. But existing method focus on the complete image retrieval, therefore lack methods of retrieving pattern elements. This article proposes a pattern elements retrieval algorithm based on cosine transform. Firstly, automatically segment the patterns according to size and location and filter the similar primary patterns, then, through cosine transform, analyze elements features in DCT domain, extract amplitude frequency and phase frequency. We employ 2-norm to measure the similarity, search 10 similar pattern elements in the sample library and save them in the design resources library. Experiment results indicate that this algorithm performs well while used in palace costume and carpet patterns, and got more than 75% of the average recall in 100 times experiments

摘要：Recently, virtual reality and interactive somatosensory technology has become one of the hot issues in the research of computer applications. Leap Motion is a new type of interactive somatosensory devices which bring users senses of immersion efficiently. This paper studies a interactive somatosensory game model based on Leap Motion and implemented with Unity. Based on the two core technology philosophy of Leap Motion, i.e., virtual reality technology and body sense of interactive technology, the design implementation of each sub module of the system and Leap Motion game algorithm are thoroughly addressed. This paper has certain significance for future application of Leap Motion in film, television, and interactive games.
