Matlab code for eye tracking

it is a file to watermark the image file in matlab

matlab中运用hough变换，设定恰当的阈值，将超过阈值的点在三维空间标示出来&将三维参数矩阵根据半径的不同做成不同的帧，制作成视频(hough transform matlab in use, set the appropriate threshold, will exceed the threshold point in three-dimensional space marked out & three-dimensional parameter matrix made of different frames depending on the radius, made into video)

Comparision SMA vs WMA

说明：  matlab小波分解,提取改变系数再重构(matlab wavelet decomposition, extraction to change the coefficient of re-reconstruction)

说明：  设计低通IIR滤波器；并将此低通滤波器映射为高通、带通或带阻滤波器。并验证变换后的滤波器是否满足指标。并求输入x(n)=[cos(w1n)+cos(w2n)]u(n)经过系统后的输出y(n)(Low-pass IIR filter design and mapping this low-pass filter high pass, band pass or band stop filter. And verify whether the filter transformation to meet the target. And to seek input x (n) = [cos (w1n)+ cos (w2n)] u (n) through the system output after the y (n))

一种拓扑优化范围中的3维SIMP程序，可以多次修改(A 3-D SIMP program in the scope of topology optimization that can be modified many times)

说明：  用于优化算法的萤火虫算法，整理和很多资料，很有用的(Optimization algorithm for fireflies, organize and a lot of information, very useful)
