用opencv实现各种低通滤波器
对图像进行滤波处理是图像处理中最常见的一种操作类型。而这其中低通滤波(也可以叫做平滑)有事各种滤波处理中最常用的。这里就简单写写 OpenCV 中提供的几种低通滤波方法。
具体思路:对源图像进行离散傅里叶变换,滤波后通过cvDFT进行傅里叶逆变换得到理想低通滤波器、巴特沃斯低通滤波器、高斯低通滤波器后图像

利用小波变换系数重构图像,实现图像降噪地方法
根据小波变换和噪声信号地能量分布特性,提出了一种先用小波变换对含噪图像进行多尺度分解,求出各尺度小波变换高频系数地噪声方差和阈值,利用各尺度地阈值对高频系数进行处理,然后利用小波变换系数重构图像,实现图像降噪地方法。(According to wavelet transform and noise signal and energy distribution characteristics, a first wavelet transform of the noisy image multiscale decomposition, obtained the high-frequency-scale wavelet transform coefficients and noise variance and thresholds, using the scale to the threshold value of the deal with high-frequency coefficients, and then the use of wavelet transform coefficients reconstructed image, to realize image denoising methods.)
