four-denosing-procedure

基本实现光流法，可以显示出两张图片中，光流的方向。(The basic realization of optical flow method, can show two pictures of the direction of flow.)

GUI的指纹特征提取,其中用到的处理函数可以自己编写，也可以直接使用Matlab的库函数(Fingerprint character extract in GUI form, within which the functions can be either designed by users or apply the available functions in Matlab)

说明：  输出带连接点的匹配影像，基于opencv(Output matched image with connection points, based on OpenCV)

说明：  可在matlab软件上实现自适应阈值分割(Adaptive threshold segmentation can be realized)

Compression of face images impact the performance of face recognition (FR) systems. JPEG Region of Interest (JROI) compression maintains high image quality in facial regions while compressing the background more, with minimal impact on FR performance.(Compression of face images impact the perf ormance of face recognition (FR) systems. JPEG Region of Interest (JROI) compression maintai ns high image quality in facial regions while co mpressing the background more, with minimal impact on FR performance.)

BPFA 算法用于图像去噪 详细的程序与说明(BPFA for image denoising)

应用傅立叶变换对图像处理，实现查看图像的功率谱，以及功率谱经过巴特沃斯高通、低通和高斯高通、低通滤波器后图像的功率谱，再把功率谱还原为图像的功能。(Fourier transform for image processing, see the image of the power spectrum, and the power spectrum after Butterworth high-pass, low-pass and high-pass Gaussian low-pass filter of the image after power spectrum, and then restore the power spectrum of the image.)

很简单的基于颜色的图像检索系统，闲时做的(Very simple color-based image retrieval system at leisure to do the)

基于不精确拉格郞日算子法的低秩矩阵重构程序，可以用于图像分割，将目标图像分割为背景和前景，从而将前景分离出来。(Lagrangian method based on imprecise low rank matrix reconstruction procedures can be used for image segmentation, the target image into background and foreground, which will separate the foreground.)

室内定位的源码，基于指纹定位的算法，把指纹存储在数据库在，然后在在线阶段根据收到的wifi信号，蓝牙信号，手机基站信号作为一个向量与数据库中存储的指纹匹配，匹配距离最短的就是指纹数据对应的位置(Indoor positioning source, location-based fingerprint algorithm, fingerprint stored in the , then in the online stage according wifi signal, Bluetooth signals, cell phone base station signals received as a vector in the matches the stored fingerprint, matching the shortest distance is a position corresponding to the fingerprint data)
