According to the relation between the change and the Fourier transform of image sequence  the method employs the displacement value of the moving target and background by the difference of Fourier phase spectrum. The algorithm estimates the movements from the whole field of the image with excellent global property. This paper provides the calculus and experiments of the algorithm which show the accuracy of 1 pixel. 2010 IEEE.   Color videos' multichannel combination for bandwidth reduction and fast frequency domain processing (EI CONFERENCE) 会议论文  OAI收割 2nd International Workshop on Education Technology and Computer Science, ETCS 2010, March 6, 2010 - March 7, 2010, Wuhan, Hubei, China 作者:  Li S. 收藏  |  浏览/下载：16/0  |  提交时间：2013/03/25 The real color video consumes much transfer bandwidth and the resource of the hardware. A new approach is introduced to process the real color video images in real-time using color components combination to fit to the limited transmission bandwidth. The Y  U  V planes of video images are packed to construct a 2 dimensional complex array. Through the decomposition of frequency domain  the Y  U  V frequency can be got respectively by performing Fourier transform a time on the specific complex array. These frequencies can be filtered to generate the final filtered images. The experiment results show that the proposed algorithm is 3X speed compared to the traditional algorithm  and it reduces 1/3 bandwidth of video data stream. 2010 IEEE.   Correction method for detection of the frequencies of railway fsk signals (EI CONFERENCE) 会议论文  OAI收割 2008 9th International Conference on Signal Processing, ICSP 2008, October 26, 2008 - October 29, 2008, Beijing, China 作者:  Yu J. 收藏  |  浏览/下载：63/0  |  提交时间：2013/03/25 In order to acquire the information of railway binary frequency-shift keying signals  which include upper/down side frequencies and base low-frequency with high-accuracy  a novel frequency detection algorithm for France UM-71 system is proposed. Combining fast Fourier transform with the ratio correction method  the carrier frequency and the base frequency are obtained. Furthermore  the hardware consumption has been decreased. And it possesses the advantage of simple algorithm and fast operation speed. Comparing with the detection of the base frequency  the upper/down side frequency of railway signal is more difficult. Based on spectrum analysis and the spectrum correction  a new method  which adopts the sliding window  is put forward in this paper. The absolute differences between the upper side frequencies and the down side frequencies obtained are regarded as the criterion for judgment. Then the set of data  in which the maximum absolute value is  is to be the result of the upper/down side frequency. Because the sliding window will go through every stage when the upper/down side frequency changes  therefore  it is not sensitive enough to the position of data which need to be transformed. Using the method mentioned above  the experiment results show that the accuracy requirement of the side frequency is satisfied well. 2008 IEEE.
