Description: 文章通过对实序列快速傅里叶变换的算法推导及Mallat 算法原理的分析，根据离散小波变换（DWT）算法结构特征，提出了一种离散小波的快速变换算法，给出了相应的算法步骤。从数学理论上进行了论证，并把该算法应用到静态图像处理中，得到了很好的快速和重建效果，具有一定的实用价值。关键词：小波分析；Mallat 算法；快速小波算法图像处理中图分类号：TN914 文献标识码：A 1 引言小波分析是近十多年来迅速发展起来的新兴学科和信号分析理论，是继傅里叶分析方法之后的重大突变。它具有时域局部化和频域局部化的优点，而且高频端的时间间隔小（有着高的时间分辨率），低频端的时间间隔大（有着高的频率分辨率），这与人的视觉机制由粗到细的认识过程相一致，固而有 “数学显微镜”之称，是进行信号处理和分析的有效工具。特别是其多分辨率分析理论及其快速算法 ——Mallat 算法在数字信号处理和数字通信-articles on real sequence Fast Fourier Transform algorithm Derivation Principle and Mallat algorithm analysis, discrete wavelet transform (DWT) algorithm structure, a fast discrete wavelet transform algorithm, corresponding to the given algorithm steps. From a theoretical mathematical proof, and the algorithm is applied to the static image processing, to be a good and rapid reconstruction effect, it is of great practical value. Keywords : wavelet analysis; Mallat algorithm; Fast Wavelet Image Processing Algorithms Key words : ODFD code : A preamble to a wavelet analysis of the last 10 years developed rapidly emerging disciplines and signal analysis theory, Fourier analysis is the method after a major mutation.

[Other resource] edege_detection

Description: 基于小波变换模极大的多尺度图像边缘检测matlab源代码，该算法采用的是样条小波，为了更好的检测边缘，用多孔算法代替了mallat算法。该算法和mallat快速算法主要区别： 1 多孔算法不需要抽取偶数样本，所以奇异检测定位更准确，相应的重构是不需要插零。2 多孔算法需要对滤波器进行伸缩。-based on wavelet transform modulus maxima of multiscale edge detection Matlab source code, The algorithm used is kind of wavelet, in order to better detect the edge of porous algorithm instead of Mallat algorithm. The algorithm and fast algorithm Mallat major difference : an algorithm porous not even take samples So singular position detection more accurate, the corresponding Reconstruction interpolation is not zero. Two porous algorithm need to filter extendable.
