Image_Filtering

梯度倒系数滤波,在小目标检测算法中,用来实现背景抑制,提高目标的信噪比.(reversing gradient filter coefficients in small target detection algorithm, which can be used for background suppression, the goal of improving the signal-to-noise ratio.)

相控阵超声成像检测，很好的一本书，从网上买的，分享给大家(Phased array ultrasonic imaging detection, a very good book, bought from the Internet and share to everyone)

在图像处理中实现带通滤波器的功能的matlab实现代码(Bandpass filter)

sift算法的完整matlab程序,本人测试过，很好，稍加修改即可！(complete sift algorithm matlab program, I tested, well, a few minor changes!)

a file abaut image segmentation

说明：  一种人脸识别方法,是利用眼睛虹膜进行识别(A face recognition method is the use of iris identification)

halcon代码 ，对图像添加高斯噪声 椒盐噪声(halcon code, add the image Gaussian noise impulse noise)

全变分程序，可以用来处理一维的信号去噪问题！！！！！(total variation)

可以在VTK下进行三维重建的DICOM数据(Three-dimensional reconstruction can be carried out in the VTK DICOM data)

说明：  可改变中心时移，相位，主频的雷克子波，自己在源程序上加减时间，改变主频，加减相位即可(ricker wavelet which time,phase and frequence can be changed )
