Description: Face Recognition System based on LabVIEW
The general process is as follows. Firstly, the original data is captured by a web camera and then transferred from RGB color space to YUV color space, where it is easier to tell the skin area from non-skin area. Afterwards we cut out the skin area, namely facial area, and run by Discrete Cosine Transform to extract the principle information in it. At last, the decision boundaries are constructed by the Euclidean distance between the query image and the one in the database.

Description: 主要为opencv人脸的美化
人脸美化，我们用的皮肤检测，皮肤在颜色空间是特定的一个区域
检测到这个区域（感兴趣区域），完后对这个区域进行美化，就是滤波，主要是双边滤波和高斯滤波。
3.视频格式转换以及编码
处理好的矩阵颜色空间是rgb的，需要转换成yuv，yuv的颜色空间就是可以播放的，类似我们电视上面看的画面，编码就是传输时候需要发送流，只个流相当于针对数据的压缩，将yuv格式的视频帧编码成h264的格式
Rgb转换成yuv，opencv实现（美颜在这一步实现）
Yuv转换成h264，x264实现
H264转换成rtmp流，libxrtmp实现-Mainly opencv face beautification facial beautification, skin test our use, skin color space is a particular area of a detected region (region of interest), after this area landscaping, is filtered, mainly bilateral filtering and Gaussian filter. 3. Video format conversion and encoding process is a good matrix rgb color space, the need to convert yuv, yuv color space that can be played, similar to watching our television screen above, the coding is transmitted when you need to send traffic only stream equivalent for compressed data, video frame coded yuv format into h264 format Rgb convert yuv, opencv achieve (achieve beauty in this step) Yuv convert h264, x264 achieve H264 convert rtmp stream, libxrtmp achieve

Description: 不同颜色空间下的人脸图像分割，彩色图像处理中有许多彩色空间坐标系，最常见的是RGB空间。其余的还有HSV空间、YCrCb空间、YIQ空间和YUV空间等，这些都可以从RGB空间转换而来。在大多数情况下，图像信息是以RGB的颜色体系保存，然而在人脸肤色分析中，由于RGB颜色的R、G、B三个颜色分量都包含亮度信息，存在极强的相关性，一般不适合肤色处理。所以一般情况下在进行肤色区域检测之前，要将RGB颜色体系转换到其他颜色体系中，而不直接利用RGB彩色空间。(There are many color space coordinate systems in color image processing, the most common is RGB space. The rest include HSV space, YCrCb space, YIQ space, and YUV space, all of which can be converted from RGB space. In most cases, the image information is stored in the RGB color system, but in the face color analysis, because the RGB color R, G, B three color components include brightness information, there is a strong correlation between, generally not suitable for skin treatment. So in general, before the skin color area is detected, the RGB color system should be converted to other color systems instead of using the RGB color space directly.)
