Image fusion technique has been widely applied to remote sensing image analysis and processing and the aim of the image fusion is to integrate the characteristic information of each image. By uniting the useful information a new image can be formed to improve the visual impression, and one can get a more accurate, comprehensive and reliable description for the same scene. In the traditional IHS transform...
This paper puts forward a novel method using dynamic programming and grey relational analysis to find a best seam line because of the grey scale difference in the edges of image in the overlapping region and the relation of neighboring points. The first step is to find an optimal seam line to stitch the images. Then the seam line is removed by a hard correction method based on dynamic width. Finally,...
This paper proposed an improved video-based texture synthesis approach for simulating realistic natural phenomena. The algorithm measures similarity of every two frames to determine a preliminary playing sequence and then divide the preliminary playing sequence into several subsequences with different frame-to-frame delay so as to remove visual discontinuities. For removing the abrupt change from...
From 1990s, with the genesis and rapid develop-ments of Kansei Engineering and Affective computing, affective information processing methods have been used to analyze and process images to extract affective features contained by images. Image retrieval by affective features attracts more and more attentions in recent years. Colorful natural scenes are a kind of images with remarkable characteristic...
Most traditional robot control software is: the operator sends commands to control the robot's movement by computer, which is complex and not very direct. The operator needs to be trained in advance and usually are technicians. While the means we discussed in this paper is: the operator controls the robot directly by computer, wearing data glove and computer generates virtual scene to assist operation...
The box counting dimension is widely used for the image processing task. In this paper, The key problems involved in the computation of differential box counting are discussed, which are the range of linear scales and the precise number of boxes, etc, then the precise computing method for box counting dimension is presented. Experiments have been performed on three kinds of images, i.e., synthetic...
Vehicle flow detection plays an important role in ITS. In the process of vehicle flow detection, the vehicle is contiguous with another and the same vehicle counted repeatedly are common problems, especially the problem of changing lanes, which is very difficult to solve. This paper uses the method that combines background difference and virtual-loop sensor to detect vehicle flow, which based on the...
There are some disadvantage in traditional "special line" networking, IP network, frame relay and the ATM network. A VPN networking project which based on MPLS is put forward in order to solve the problem. Then analyze the realization of MPLS VPN. The simulation principle, simulation process and simulation scenes are introduced by OPNET, get the results that MPLS VPN has lower delay and...
Dynamic water surface simulation is an important part of simulating natural scene. Ben Humphrey used projection texture mapping, depth texture and mobile texture to render dynamic water surface and got a good result. In this paper, an improvement method will presented for speeding up its rendering speed and enhancing the rendering effects. It uses a viewpoint correlative method to replace depth texture...
An improved cost proxy model is established in the following, where the extreme imbalance between urban and rural area as well as complicated geographic environment of China was taken into consideration. On the one hand, new parameters were introduced into scene variant vector so as to prescribe urban and rural differences and also topographical differences. On the other hand, in order to analyze...
A water distribution network model which was based on virtual reality was constructed and the state-of-art was simulated in a 3D scene. It works with a clear sense. The water network engineering database was built firstly in this paper to keep the precision of the 3D model. The water network model was constructed after the 3D models of the valves and pipes were made. The model was driven by the Vega...
In this paper, a MAPSACLM algorithm for feature point matching is proposed. This method integrates the MAPSAC algorithm with nonlinear optimization by using the results of MAPSAC as the initial value of the fundamental matrix and homography matrix. Firstly, gray level cross-correlation matching method was used to realize initial matching. Secondly, the fundamental matrix and the homography matrix...
This paper proposed an adaptive shadows detection algorithm based on Gaussian Mixture Model to improve the performance of video object segmentation. This method takes advantage of luminance weight to model the background of the image and obtains a primary segmentation in CIE Luv color space. In this way, it improves the real-time ability of detection. It also becomes more efficient, comparing with...
