查询词典 shortcoming

A new scheme for approximating the solution of 2D Maxwell's equations-the high order symplectic scheme is proposed to overcome the shortcoming of the conventional finite difference time domain. The scheme is obtained by discretizing the Maxwell's equations in time domain based on symplectic scheme with high order, and then evaluating the equation in spatial domain with second or fourth order finite difference approximation.

为克服标准时域有限差分方法的缺陷，引入一种新的数值计算方法－高阶辛算法求解Maxwell方程，即在时间上用高阶辛差分格式离散，空间分别采用二阶及四阶精度的差分格式离散。

based on the introduction of the merit and shortcoming and the analysis of the generate methods of the main random sequences,we propose a new method which is based on the substitution and recurrence structure,and the method is implemented by fpga.the generated sequences by this method not only can pass the test of the fips 140-2 standard,but also have high performance:long period,high linear complexity,good correlation function value and high generation speed,it can be used widely in information security system and so on.

摘 要：在介绍了现有随机序列的优缺点以及分析随机序列主要产生方法的基础上，提出了一种基于循环替换原理的伪随机序列产生方法，并用fpga加以实现。该方法产生的伪随机序列完全符合fips140-2标准，并具有周期长、线性复杂度高、相关性好以及产生时间短的特性，能广泛应用于信息安全等系统中。

At present, most of the image watermarking algorithms based on the wavelet transform fail to take into account the shortcoming that the first generation wavelet transform used in image processing will introduce quantization errors inevitably, because of the storing characteristics of the image. Wavelet transform that maps integers to integers will not introduce quantization errors. Its time-frequency analysis method and multi-scale property accordant with human being vision system makes integer wavelet transform an ideal way for digital watermarking.

目前，大多数基于小波变换的图像水印算法没有考虑到第一代小波变换用于图像处理中不可避免的引入量化误差的缺点，而整数小波变换除了具有小波的多分辨率分析与人类视觉特性一致、具有良好的时频特性等优点以外，还避免了第一代小波变换用于图像处理中引入量化误差等缺点。
