vortex beam

用于计算图像每个像素点的恰可识别阈值（JND），该模型为Chou所提出。(This model was used to estimation the just-noticeable difference of pixel in image, which was proposed by Chou.)

此程序为摄影测量的一个小环节，主要功能是求解影像畸变差，可根据相机内参数求解，简单实用(This program is a small part of photogrammetry, the main function is to solve the differential image distortion can be solved according to the camera parameters, simple and practical)

人体脑信号波形检测与分析,包含自相关,功率谱分析的方法(Human brain signal detection and analysis, including autocorrelation, the method of power spectrum analysis)

能够实现土壤水分和光照度的数据的显示与保存(Data can be achieved degree of soil moisture and light display and preservation)

说明：  MATLAB源代码实现BP人工神经网络算法。(BP Neural Network based on MATLAB. )

图像保重要特征扩散滤波方法之-----非线性扩散(important feature images Bao proliferation filtering method----- Nonlinear Diffusion)

说明：  利用经典免疫遗传算法实现单阈值图像的分割。(Classical immune genetic algorithm is used to segment single threshold image.)

对可见光图片的人脸活体判断，内有C++和matlab实现，具体说明详见readme(For the visible light picture of the human face to determine, there are C++ and matlab implementation, specific instructions see readme)

说明：  fast RPCA背景检测,较为经典的一种算法，亲测可用(fast rpca method for background selection)

图像变换 将图象分块(8*8)，作DCT变换，并作IDCT：DCT是一种可分离图象变换，用来图象压缩编码，IDCT用来解压缩(Image transform to image sub-block (8* 8), for the DCT transform, and IDCT: DCT is a separable transform image to image compression coding, IDCT used to extract)
