卡尔曼滤波、无迹卡尔曼滤波、扩展卡尔曼滤波等滤波程序，本人收集了实验室所有这个方面的程序，欢迎大家下载，非常好用~(Kalman filtering, unscented Kalman filter, extended Kalman filtering, filtering program, I collected all the aspects of laboratory procedures, are welcome to download and very easy to use ~)

改进的OPTA，通过设置保留模板，图形细化算法，matlab(Improved OPTA, retained by setting the template graphics thinning algorithm, matlab)

读取一24位彩色图像，计算其以下图像特征： 1）灰度直方图 2）颜色直方图（RGB3个通道） 3）方向梯度直方图（HOG，将图像分成4*4 16个块，8个梯度方向） (Read a 24-bit color images, calculate the following image features: 1) Histogram 2) color histogram (RGB3 channels) 3) histogram of oriented gradients (HOG, the image is divided into 4* 4 16 blocks, 8 gradient directions))

利用非局部特性并结合低秩解法的图像降噪算法，速度很快(Nonlocal properties combined with low rank Solution image noise reduction algorithm, fast)

用matlab仿真，研究不同阈值降噪后的效果，使用penalty阙值降噪后信号，使用Birge_Massart阙值降噪后信号，使用缺省阙值降噪后信号。(Using matlab simulation to study the different threshold noise reduction effect, the use of penalty threshold denoised signal after noise reduction using Birge_Massart threshold signal, use the default threshold signal after noise reduction.)

该源代码主要是利用bagging,adboosting等集成学习的方法进行图像融合处理，效果甚好！(The main source is the use of bagging, adboosting ensemble learning methods such as image fusion, the effect is very good!)

维纳滤波器仿真，是对基本算法原理的实现，没有考虑误差模型(Wiener filter simulation, the realization of the basic algorithm principle, without considering the error model)

经典的图像处理常用图片，包括Lina，Barbana, Cameraman(Classic image processing commonly used pictures, including Lina, Barbana, Cameraman)

压缩感知重构算法，在经典的SP基础上进行的改进，提高了性噪比，以DWT为稀疏基。(Compressed sensing reconstruction algorithm, improved on the basis of the classic SP carried out to improve the signal to noise ratio, DWT is sparse groups.)

现场指纹的方向场，四种方法比较OF_FOMFE，OF_manual，OF_proposed，OF_STFT(latent fingerprint orientation，orientation field estimation for latent fingerprint enhancement)
