本课题的主要内容是图像预处理,它主要从摄像头中获取人脸图像然后进行处理,以便提高定位和识别的准确率.该模块主要包含光线补偿、图像灰度化、高斯平滑、均衡直方图、图像对比度增强，图像预处理模块在整个系统中起着极其关键的作用，图像处理的好坏直接影响着后面的定位和识别工作-The main content of the subject image preprocessing, mainly from the camera to obtain images Face then be processed i

首先提取印刷品的数字图像，对图像进行预处理，然后用模板匹配将图像中的文字部分分割出来，在提取文字图像的特征参数，最后对照标准样张图像的特征参数分析该印刷品的印刷质量，得到质量数据。-First extract the print of digital image, the image preprocessing, and then the text part of the image segmentation with template matching, text image feature
