This paper first analyses some basic theory of traditional wavelet such as multiresolution , the mallat algorithm and biorthogonal filter sets 论文首先分析了传统小波变换的一些基本知识,如多分辨分析, mallat算法以及双正交滤波器组等。
A multiwavelet is a wavelet generated by a scaling vector function that consists of several functions . multiwavelet is associated with multiresolution analysis ( mra ) 多小波( multiwavelet )是指由两个或两个以上函数作为尺度函数生成的小波。
We add several icons in addition to the first one . all in multicolor / multiresolution xp - compatible xxl - nice versions to be used for shortcutlinks on desktop 我们为第一个加入了多个图标,所有多色/多分辨率xp兼容的特大版本将被用于在桌面上快捷方式。
The method decomposes an image with multiresolution to get a set of sub images , which depicts the information the index image from global to local precision 该方法首先提取检索图像在不同分辨率情况下的信息,然后统计多分辨率直方图作为特征索引的信息。
Methods based on spatial frequencies , co - occurrence matrixes and multiresolution methods have been frequently employed for texture description because of their efficiency [ 3 . 69 ] 这些方法基于空间频率,共生矩阵及多分辨率法由于效率高而常被纹理描述运用。
So , we can finish the collection and resume of signal by using the data acquisition system by using multi - channel structure based on wavelet and multiresolution . 3 3 .研究了最小频宽的正交镜像滤波器和具有线性相位的正交镜像滤波器的设计方法,给出了设计结果。
Because wavelet analysis has excellent characteristic in timefrequency multiresolution , it has been rapidly developed in the field of information processing in recent ten years 小波分析具有出色的时间?频率域多分辨特性,十多年米在信息处理领域得到了迅速的发展。
The background is rendered with panoramic image based on multiresolution spline and represented as multiresolution level , so as to improve the speed 背景采用第二章提出的基于多分辨率样条的图象拼合算法拼合成圆柱形全景图,并用多分辨率样条层次表示,以提高绘制速度。
