中文简介:
小波是局部基函数,适用于表示短时事件。对每个尺度的系数进行滤波和二次采样,以给出下一尺度的系数。这是Mallat用于多分辨率的金字塔算法,将小波连接到滤波器组。开发了用于压缩和信号/图像处理的小波和多尺度算法。主题是基于项目的工程和科学应用。
课程简介: Wavelets are localized basis functions, good for representing short-time events. The coefficients at each scale are filtered and subsampled to give coefficients at the next scale. This is Mallat's pyramid algorithm for multiresolution, connecting wavelets to filter banks. Wavelets and multiscale algorithms for compression and signal/image processing are developed. Subject is project-based for engineering and scientific applications.
关 键 词: 局部基函数; 尺度系数; 小波滤波器; 科学应用
