Based on the gray square weighted centroid localization algorithm  the paper presents bicubic interpolation gray square weighted centroid localization algorithm  increases the number of effective pixels around the optical characteristic point imaging center  and reduces noise error via the gray square weighted  improves the imaging center location accuracy of optical characteristic point  realizes the accurate location of the optical characteristic points. Results indicate application of the proposed algorithm to location  the standard tolerance along the direction of x is 0.0022 Pixel  the standard tolerance along the direction of y is 0.0023 Pixel  compared with the others  the standard tolerance is minimum and discrete to a lesser degree distancing ideal image point  that is  the proposed algorithm has higher location accuracy. The maximum tolerance along the direction of x is 0.008 Pixel  the one along the direction of y is 0.007 Pixel  compared with the other two algorithms  the maximum tolerance is minimum.Results indicate that the stability of the proposed algorithm is better. (2013) Trans Tech Publications  Switzerland.   An LCoS microdisplay with new frame buffer pixel circuits (EI CONFERENCE) 会议论文  OAI收割 Second Americas Display Engineering and Applications Conference, ADEAC 2005, October 25, 2005 - October 27, 2005, Portland, OR, United states Song Y.; Ling Z. 收藏  |  浏览/下载：15/0  |  提交时间：2013/03/25 In this paper we proposed novel frame buffer pixel circuits for LCoS microdisplays. The new pixel circuits were simulated and compared with others by SPICE. They can decrease the leakage current by minimizing the amount of transistors connecting with the pixel electrode in the voltage-holding period. And the PMOS charge-clear transistor is introduced firstly to simplify Interconnects of active matrix silicon backplane. The new pixel circuits have the advantages of high resistance to EMI  high voltage holding ratio under high Illumination and high temperature variance  less flick  and simple Interconnects.
