小波增强
- 图像的小波变换，利用小波进行图片的增强，有一些例程(Image wavelet transform, wavelet transform for image enhancement.)
傅里叶变换
- 一种积分变换，它来源于函数的傅里叶积分表示。积分 (1) 称为? 的傅里叶积分。周期函数在一定条件下可以展成傅里叶级数，而在(－∞,∞)上定义的非周期函数?，显然不能用三角级数来表示。但是傅里叶建议把?表示成所谓傅里叶积分的方法(An integral transform that is derived from the Fourier integral representation of a function. IntegralFourier integral . The periodic f
DFT(傅里叶变换)
- 傅里叶变换在图像处理中被广泛应用，该算法实现了傅里叶变换的基本代码。(This algorithm implements the basic code of the Fourier transform.)
小波阀值去噪
- 利用小波变换实现图像去噪，对比原图观察去噪效果(Image denoising is realized by wavelet transform, and the effect of noise reduction is compared with original image.)
