Matlab 梳状滤波器程序
心电图(ECG)是临床上诊断心血管疾病的重要方法。
数字滤波作为数字信号处理技术的重要组成部分,广泛应用于诸如信号分离、恢复、整形等多种场合中。为了使信号不失真及在可编程逻辑器件中容易实现,采用具有严格线性相位特性的FIR滤波器进行低通滤波(0-150Hz),用整系数梳状滤波器来去工频干扰及基线漂移,从而达到对心电信号进行预处理的目的。(Electrocardiogram (ECG) is an important method for clinical diagnosis of cardiovascular diseases.
As an important part of digital signal processing technology, digital filtering is widely applied to many occasions, such as signal separation, recovery, shaping and so on. In order to make the signal undistorted and easy to be realized in programmable logic device, the FIR filter with strict linear phase characteristics is used for low pass filtering (0-150Hz), and the entire coefficient comb filter is used to get the interference of the power frequency and the baseline drift, thus the purpose of preprocessing the ECG signal is achieved.)

ImageInpainting
说明: Curvelet变换是由一种特殊的滤波过程和多尺度脊波变换组合而成:本程序对彩色图像进行了curvelet变换从而实现图像去噪的效果。首先对图像进行子带分解;然后对不同尺度的子带图像采用不同大小的分块;最后对每个分块进行Ridgelet分析。(Curvelet transform is a combination of a special filtering process and multi-scale ridgelet transform. In this program, curvelet transform is applied to color image to achieve the effect of image denoising. First, the image is decomposed into sub-band; then the sub-band images of different scales are divided into different sizes; finally, each sub-band image is analyzed by ridgelet.)

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
