My paper accomplishes the problem of recognizing the license plate number from the license plate image with a simple and fast method in order to resolve the problem that is too complicated and high cost in recognizing license plate number of Intelligent Transportation System. This paper extracts the license plate image from rows and lines with the method of counting color pixels. We use the method...
This paper proposes an image matching method based on hybrid PSO. The method combines the advantage of the rapid global optimization ability of PSO, and introduces the idea of Population Category Evolution and the mechanism of SA to improve itself. Adopting different evolutionary strategies for different particle categories and making the individual optimal value of the particle accept a lower value...
With the development of the electronics and information technology, the requirement of people toward the resolution of images become higher. However, the resolution of acquired images can't meet our needs because of the different imaging system from a variety of factors. And it will cost too much to improve image resolution via using the physical hardware. So it requires a new method to solve this...
A intelligent supervising and control system about multi-factors are researched and applied in aquiculture. Expert system and image processing are introduced to automatically diagnose and predict the illness of fish. Remote sampling and control of data are realized by mobile GPRS telecommunication technology and Internet technology. The test results prove that the system can be operated simply and...
To solve the problem of huge computation in the solution process of using Hough Transform (HT), an improved HT algorithm based on Freeman criteria has been presented and used to locate window region for the envelope image successfully. The improved algorithm detects the whole image using a template with size of N*N and the center pixel of template, replacing other pixels in template, is calculated...
Watermarking technology is an effective approach to image content authentication and copyright protection, which has got notable achievements in recent years. In different frequency intervals of discrete cosine transformation(DCT), compared the characteristics of the watermarking algorithm, an embedding and detection algorithm was proposed. It can solve the explanation attack well and improve the...
Land use change is a major issue in global environment change and is especially significant in rapidly developing urban regions of China was being witnessed. With its economic development, population growth, and urbanization in Chengdu, capital of the western province of Sichuan, China, have experienced a dramatic land use change over the past 30 years. Assessment on urban land use change is essential...
In this paper we propose an image super-resolution algorithm using The Morphological Component Analysis(MCA) and wavelet-domain Hidden Markov Tree(HMT) model. The MCA is a useful method for signal decomposing, using proper basis, we could separate features contained in a signal when these features present different morphological aspects. Wavelet-domain HMT models the dependencies of multiscale wavelet...
For the purpose of training the periscope operator on shore, the periscope scene simulation system is designed based on VR technology. The structure of system is introduced at first. Then the method using stencil buffer to achieve the periscope circle window clipping is proposed, which can efficiently ensure the clipping and has little influence in rendering effect. By changing the vertical and horizontal...
Electronic Travel Aid (ETA) technology can be used to help blind people walk. Blind users can judge current environment with the prompt of ETA system. The portable ETA system is a model of ETA system which is simple in structure, easy to carry, easy to use and low cost. One of the important research is how to extract the orientation of the blind sidewalk accurately. This paper using the methods of...
