	Color filtering method for CFA images based on gradient (EI CONFERENCE) 会议论文 OAI收割 International Conference on Communication Systems and Network Technologies, CSNT 2012, May 11, 2012 - May 13, 2012, Rajkot, Gujrat, India 作者: Wang Y.; Wang Y.; Wang Y.; Wang Y.; Wang Y. 收藏 \| 浏览/下载：34/0 \| 提交时间：2013/03/25 Single-sensor digital cameras capture image by covering the sensor surface with a color filter array(CFA) such that each sensor pixel only samples one of three primary color values three color is R(red) G(green) and B(blue). To render a full-color image need an interpolation process commonly referred to as CFA demosaicking is required to estimate the other two contributions for producing a full-color image. But the noise in imaging sensors not only corrupts the color filter array at the same time introduces artifacts during the color interpolation step and influence quality of images. In order to acquire high quality full-color images adopt a sort of viable and effective interpolation algorithm based on gradient at the time of removing the noise reserve image border and detail information clearly. 2012 IEEE.
	DirectShow application in LED panel display system (EI CONFERENCE) 会议论文 OAI收割 2009 International Conference on Information Technology and Computer Science, ITCS 2009, July 25, 2009 - July 26, 2009, Kiev, Ukraine Tao L.; Ding T.-F. 收藏 \| 浏览/下载：37/0 \| 提交时间：2013/03/25 A new DirectShow application in the field of LED Panel display system is shown in this paper. It realizes video processing functions with DirectShow architecture on computer. Source Filter and many Transform Filters which provided by Microsoft Co. transform source video into RGB24 format. Then the video data are scaled up/down to LED panel resolution by Fixformat Filter which inherite CTramsformfilter baseclass. After that the R/G/B values of video data are adjusted in CCorrect Filter to adapt LED Panel display. Finally the processed video is shown on LED Wall through DVI or VGA interface. Our experimental results demonstrate that this system makes a good performance. It is greatly simplify the functions of Sending-Board Receiving Board and Control-Scanning-Board in display system of the LED Wall. The total cost will be cut down observably if we can transplant the filters into the embedded platform to build a special video processing system for LED Panel display. 2009 IEEE.
	Low drive-voltage and high-bandwidth electro-optic modulators based on BaTiO3 thin-film waveguides (EI CONFERENCE) 会议论文 OAI收割 Science and Technology of Dielectrics for Active and Passive Photonic Devices - 210th Electrochemical Society Meeting, October 29, 2006 - November 3, 2006, Cancun, Mexico Sun D. G.; Fu X. H.; Liu Z. F.; Ho S. T.; Wessels B. W. 收藏 \| 浏览/下载：45/0 \| 提交时间：2013/03/25 We investigated electro-optic modulator structures to target low drive voltage high-speed modulation and small device size with c-axis grown BaTiO3/MgO ferro-electric thin films. In this study the calculations are focused on the ideal thin film with a quadratic relation between the half-wave drive voltage V and the interaction length L in the electro-optic modulation case we obtained in previous work. With the quadratic electro-optic modulating relation and the optimal rib waveguide structure of BaTiO3/MgO thin films the frequency-voltage-size performances for 2.5GHz 10GHz 40GHz and 100GHz modulation bandwidths have been obtained under half-wave drive voltages of 0.8V 1.6V 3.0V and 4.8V respectively for the ideal film with r51=730 pm/V at 1550nm wavelength where both the phase velocity matching condition and the conductor induced microwave attenuation are considered. The required device lengths to achieve these four typical values of modulation bandwidth are 3.3 mm 0.8 mm 0.4 mm and 0.2 mm respectively. With the c-axis grown BaTiO3/MgO crystal thin films and the quadratic electro-optic modulating relation an electro-optic coefficient of reff=180 pm/V for the c-axis grown BaTiO3/MgO ferro-electric thin films was measured which is relatively far from the ideal value of r51=560 pm/V. copyright The Electrochemical Society.
