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

FusionCode1
- 针对多聚焦图像融合,本文首先介绍了小波变换融合算法,虽然小波变换方法无冗余,高频分量损失较小,具有较好的融合效果,但存在两个主要缺点:一是移变性,二是融合图像在重构时会受到一些外来因素的影响,所以仍会丢失一些边缘信息,为了克服小波变换法的以上缺点,可以采用基于小波分解和点扩展函数模型PSF相结合的融合方法。该方法首先对不同的图像进行无降2采样的小波分解,以保持与源图像大小相同,然后分别将其各方向、各尺度的高频分量进行叠加,并依此提取其高频分量的特征信息来判定清晰目标或模糊目标,以此来设计融合算法
