Active-Contours

是希尔伯特黄变换的c++源代码，帮助大家一起学习，更进一步的了解希尔伯特黄变换(Is the Hilbert-Huang transform c++ source code to help people learn together, a better understanding of Hilbert Huang Transform)

calculate Gaussian filter for images using matlab

说明：  这是一个用Matlab编写的提取图像轮廓并且标示出图像中拐点的例子，输出拐点的坐标。(This is an extract prepared using Matlab image contours and marked a corner in the example image, the output coordinates of corner.)

说明：  应用于各种雾天条件下对图像进行雾去除，可以得到清晰无雾的效果图，是一个不错的图像恢复工具(a method of haze removal,we can gain a haze-free image)

用于仿真正负线性调频信号在同时极化测量中的性能(Simulation of positive and negative for the chirp signal at the same time measuring the performance of polarization)

说明：  对视频序列通过背景减除法进行运动跟踪，里面用到的方法是叠代法(Motion tracking video sequences by background subtraction)

层叠中值滤波和层叠秩排序滤波的Matlab实现。(Cascaded median filtering and layering rank order filtering Matlab implementation.)

杨氏双缝干涉 两相干光源到接收屏上P点距离r1=(D2+(y-a/2)2)1/2, r2=(D2+(y+a/2)2)1/2, 满足相干条件的光波叠加后，对于观察屏上某一确定点，即r1、r2确定后，叠加后的光强为 式中λ为光波的波长， 、 ，令相位差φ=2π（r2-r1）/λ, 最后可得公式如下： ， 最后光强I=4I0cos2（Φ/2）。 观察相干光叠加后光强的分布. (Young' s double slit interference two coherent light source to the point P on the receiving screen distance r1 = (D2+ (YA/2) 2) 1/2, r2 = (D2+ (y+a/2) 2) 1/2, meet coherent conditions lightwave after superposition, for a determined point on the viewing screen, i.e. R1, R2 is determined, the superimposed light intensity where λ is the wavelength of light, make the phase difference φ = 2π (R2-R1)/λ, final can be obtained using the following formula: Finally, the light intensity I = 4I0cos2 (φ/2). Observed coherent superposition of light intensity distribution.)
