二维小波变换
- 关于二维小波变换的程序 [精华] 说明:此算法重在概念,速度并不是很快。因为FOR循环的缘故。此程序从循环矩阵的观点出发,把圆周卷积和快速幅里叶变换建立了联系。实现了分解和无失真重构。它只做了一层分解,即将256x256图形分解成为64x64的四个图形,避免了使用WKEEP()的困惑。主要思想为用小波滤波器族构造正交阵W,变换写为B=W*A*W ,反变换为:A=W *A*W,这与所有正交变换无异。W为循环正交矩阵,因此可用FFT实现快速运算,难点就在重构矩阵上。若用矩阵概念明确,一个

小波变换在活塞环图像边缘检测中的应用研究
- 摘 要 小波变换是时间频率的局部化分析,它可以通过伸缩平移运算对信号逐步进行多尺度细化。本文正是基于小波变换在图像处理领域中表现出的多尺度分析,提出了用小波变换检测活塞环图像边缘的方法,这种方法通过对二维小波变换图像局部极大值的检测得到图像的边缘信息。通过实验证明了这种方法的有效性。-Abstract wavelet transform is the local time frequency analysis, it can shift computing through telescopic
