Abstract: In order to support the transport aircraft mission simulation for evaluating and optimizing the air transport plans, a schedule system is researched. Firstly, the method of the schedule system to handle the typical transport aircraft mission which can be divided into ground sections and flight sections is described. Moreover, the ground section is composed of several ground services such as fueling and on/off-loading. Secondly, the user interface which presents the schedule table by color bars is introduced. Next, the operating mode of the schedule system which is responsible for judging the time status and aircraft in simulation calculation is introduced. A sample case which includes eight aircraft flying in sequence is provided. The result of the sample case verified the schedule systems ability for promoting the mission simulation process.

Abstract: This paper attempts to explore the application possibilities of a author programmed multi-agent system in a residential cluster layout in Beijing which was originally designed by the traditional approach. The author analyzed and evaluated the layouts with three environmental indices: relation with road, relation with green land, location in the building. The solution showed that the computer could generate the well performed layouts which could still be improved by the traditional approach. The cooperation of these two approaches can make the design process efficient, digital evaluated, controllable, aesthetic and creative.

Abstract: Image denoising is still a challenging problem for researchers. The conventional methods for image denoising often smooth the images and result in blurring the edges. In this paper, however, we consider not only the noise removal ability but also another important requirement for image denoising procedures that is true image structures, such as edges, should be preserved. To this end, we propose a maximum a posterior (MAP) image denoising algorithm using a novel edge-preserving Markov random field (MRF) model. Considering edges tend to be continuous in space, the connectivity of structure tensor is defined to describe edges. And the revised Markov random field model is proposed by using the edge connectivity, which can adaptively control the degree of smoothing. The experiments show that our new method gives superior performance in terms of both objective criteria and subjective human vision when compared with related MRF models.

Abstract: In order to reduce the complexity and computation of the background extraction algorithm, this paper presents a new background extraction algorithm corresponding to the intelligent traffic environment based on the invariance of background. In the algorithm, we partition the background into sub-blocks, and compare the characteristics of the several continues frames in the video stream, then update the background block by fuzzy similarity processing in real time. The evaluation proves that the new algorithm can accomplish the higher efficient extraction with less computation complexity.

Abstract: In the paper, we discuss the image demising models, based on partial differential equations. It is through the use of the concept of variations in the calculus of the objective function minimization problem, defines the image processing tasks. The results show that the model expands 2d thermal diffusion equation. Therefore, it is easy to get solution is to use a simple iterative process.

Abstract: In this paper, the simulation functions of computer three-dimensional model as well as the advantages in the simulated application are briefly introduced, and also the application of the three-dimensional models simulation functions to the different industries is discussed in details.

Abstract: FSK is a prior modulation scheme in the information transmission. It has many advantages such as convenience to realize, anti-noise and antiattenuation, so it is widely used in middle and low-speed data transmission. This paper designed a FSK system based on TMS320VC5402 DSP, The scenario analysed the arithmetic of FSK and realized it using C. This system produced FSK signal using keying. That means, two sine waves which have different independent frequencies represented the 0s and 1s of digital signals respectively, the data of one sine wave was composed of 64 points. The arithmetic stored the modulation data at a specific address; the author can observe the output wave by graphic display tools. Finally, the author verifies the accuracy and feasibility of this FSK system.

Abstract: Most of the existing literature research how to combine the three dimensional geometry model 3 d geographic information systems (GIS) technology, such as houses, trees, and so on. The grid model 3 d geometric features rare, they have less data, but the poor real-time problems still exist. It rarely have in the literature that the 3 d GIS and fog increase, it has a larger data particle system model. Therefore, this paper aims to study more deeply. Therefore, the 3 d GIS visualization algorithm is proposed on the basis of image processing method, and the results show that, with the real scene to the time cost less.
