Using the principle of limited rigid body rotation and the characteristic of angular rate input  three-sample rotation vector algorithm is derivated. To minimum attitude errors  three-sample rotation vector algorithm is optimized. Three angular rate extraction methods of singlestep entire sample recursion  multi-step entire sample and singlestep Newton backward interpolation are proposed. Under the condition of conical motion with semi-cone angle 3 and angular frequency 2rad/s  simulation is done. The simulation results show that single-step Newton backward interpolation is superior to the other two methods  and its maximum error peak is 0.01  error drift rate is 0.036/h. Experiments in three-axis flying turntable with the same parameters are carried out  and the results show that error drift rates of three-channels are less than those of traditional quaternion  which are 13.53%  12.08% and 23.68% lower respectively. It also verified that the new algorithm can perform a high accuracy under the conical motion. 2011 IEEE.   A fast and efficient multiple step algorithm of iris image quality assessment (EI CONFERENCE) 会议论文  OAI收割 2010 2nd International Conference on Future Computer and Communication, ICFCC 2010, May 21, 2010 - May 24, 2010, Wuhan, China Shi C.; Jin L. 收藏  |  浏览/下载：15/0  |  提交时间：2013/03/25 Iris recognition is one of the most reliable methods of biometrics personal identification. Poor quality iris image will be rejected by recognition system  which will result in the failure of recognition. Therefore iris image quality assessment is very essential to the iris recognition system. In this paper  a multiple step algorithm of iris image quality assessment is proposed to distinguish two kinds of poor quality images  i.e. defocus and occlusion. Experimental results show that the proposed algorithm is fast and efficient for iris image quality assessment. 2010 IEEE.
