Coarse alignment cannot be done by micro inertial measurement unit (MIMU) itself because of its low precision  the method of using magnetometer to assist it with coarse alignment is presented. Simulation results show that the adaptive UKF can overcome the influences of initial values error and inaccurate system model  and improve the convergence speed and alignment accuracy effectively. 2010 IEEE.   High speed, low memory image coding using zero blocks of wavelet coefficients (EI CONFERENCE) 会议论文 4th International Conference on Image and Graphics, ICIG 2007, August 22, 2007 - August 24, 2007, Chengdu, China Yang W.-G.; Zhang T.; Zhang J.-D. 收藏  |  浏览/下载：21/0  |  提交时间：2013/03/25 We propose a new high speed  low memory SPECK image coder based on the form of block-unit states  called LBUS-SPECK  which uses the form of block-unit states and the form of block exponents to substitute LIS and LSP of SPECK. A form of block-unit states is introduced to store the significance flag of coefficients and the value of the block-unit exponents. A form of block exponents is introduced to store the block exponents which are used to represent the max coefficient in a decomposed block. A new block depth-finding strategy is developed for searching insignificant sets at sorting stage. Experimental results show that the obtained PSNR values for the decoded images are very close to those of SPECK algorithm and the memory consumption is reduced by 9 times  the encoding timing is saved about 15%. Comparing with SPECK algorithm  this algorithm not only has better performance of the decoded images  but also is easy to implement  especially  it provides an efficient way for hardware implementation of wavelet embedded block coding. 2007 IEEE.
