Thus the efficient image compression method should be used to decrease the bit rate. The image compression method based on wavelet is used more widely nowadays. However  two dimensional wavelet is only the tensor product of the one dimensional wavelet whose support region of basis function is extended from interval to square. Contourlet is an image multiscale geometric analysis tool  which could represent image sparsely and has strong capability of nonlinear approximation. The basis function of contourlet is multidirectional and anisotropic. Nevertheless  contourlet is redundant. So the non-redundant Wavelet Based Contourlet Transform (WBCT) is used in this paper. The SPIHT algorithm is very efficient way to coding the significant coefficients. And the improved no lists SPIHT is more easy to implemented by hardware. Image compression method based on the combination of both wavelet based contourlet transform and no lists SPIHT coding is proposed in the paper. Experiment shows that compared to wavelet based scheme the contourlet scheme can reserve the texture of the image. For barbara test image when coding at low bit rate the PSNR can improve about 0.2dB. 2010 IEEE.   analysis of zipper as a hash function 会议论文  OAI收割 4th Information Security Practice and Experience Conference (ISPEC 2008), Sydney, AUSTRALIA, APR 21-23, Lin Pin; Wu Wenling; Wu Chuankun; Qiu Tian   |  收藏  |  浏览/下载：9/0  |  提交时间：2011/06/13 Zipper  hash function  compression function   Electromagnetic modeling due to line source in frequency domain using finite element method 期刊论文  OAI收割 CHINESE JOURNAL OF GEOPHYSICS-CHINESE EDITION, 2006, 卷号: 49, 期号: 6, 页码: 1858-1866 作者:  Wang Ruo;  Wang Miao-Yue;  Di Qing-Yun   |  收藏  |  浏览/下载：36/0  |  提交时间：2018/09/26 frequency domain  line source  finite element method  forward modeling  first order absorption  boundary condition  compression storage of the coefficient matrix  pseudo delta function  Gauss-Seidel iteration method   Electromagnetic modeling due to line source in frequency domain using finite element method 期刊论文  OAI收割 CHINESE JOURNAL OF GEOPHYSICS-CHINESE EDITION, 2006, 卷号: 49, 期号: 6, 页码: 1858-1866 作者:  Wang Ruo;  Wang Miao-Yue;  Di Qing-Yun   |  收藏  |  浏览/下载：47/0  |  提交时间：2018/09/26 frequency domain  line source  finite element method  forward modeling  first order absorption  boundary condition  compression storage of the coefficient matrix  pseudo delta function  Gauss-Seidel iteration method   压缩函数局部平衡度与Hash函数平衡度的关系研究 期刊论文  OAI收割 中国科学院研究生院学报, 2006, 卷号: 23, 期号: 3, 页码: 412-415 奚青; 吴文玲   |  收藏  |  浏览/下载：26/0  |  提交时间：2010/08/20 hash函数  平衡度  碰撞  压缩函数  局部平衡度 hash function  balance  collision attack  compression function  partial balance   Optimization feature compression and FNN realization 期刊论文  OAI收割 INTELLIGENT CONTROL AND AUTOMATION, 2006, 卷号: 344, 页码: 951-956 作者:  Ding, Shifei;  Wang, Yuncheng;  Shi, Zhongzhi;  Jin, Fengxiang   |  收藏  |  浏览/下载：22/0  |  提交时间：2019/12/16 pattern recognition  optimization feature compression  entropy density function (EDF)  representation entropy (RE)  feedforward neural network (FNN)   pitch estimation based on circular amdf 会议论文  OAI收割 IEEE International Conference on Acoustics, Speech, and Signal Processing, ORLANDO, FL, MAY 13-17, Zhang WY; Xu G; Wang YG   |  收藏  |  浏览/下载：18/0  |  提交时间：2011/07/29 AMDF  CAMDF  HR-AMDF  LVAMDF  average magnitude difference function  circular AMDF  estimation error reduction  pitch detection algorithm  pitch estimation  pitch period  speech compression  speech recognition  speech synthesis  voicing detection  paramet   Atomic simulation of shock compressed liquid helium 期刊论文  OAI收割 PHYSICA B, 1999, 卷号: 269, 页码: 304-309 作者:  Cai, LC;  Chen, QF;  Zhang, JL;  Chen, DQ;  Jing, FQ   |  收藏  |  浏览/下载：29/0  |  提交时间：2018/05/31 liquid helium  molecular dynamics simulation  shock compression  Hugoniot equation-of-state  radial distribution function
