行人检测分类器的训练，训练完可测试效果如何，注意样本的路径问题

作者：BERNTSCHIELE其是计算机视觉以及模式识别方面权威人士，本文重点总结HOG+SVM在分类识别方面的性能，并同其它算法如Adboost,Shapemodebased等都作为了比较，相信对于这方面技术比较感性趣的朋友读完此文之后，对于整个识别算法方面有一个比较全面的了解！

自己写的一点代码，HOG+LBP作为检测，并用了SVM的学习方法

配置好opencv249和VS2012的环境之后，设置好工程项目的属性，运行HOGvisualize\Debug或HOGvisualize\Release目录下的opencvtest.exe程序便可看到运行结果，即objimg.jpg图片的hog特征可视化图像hogvisualize.jpg。
程序里有较为详细的注释，可以帮助理解hog特征的可视化过程，希望此程序对你有帮助，谢谢。

在日常工作中，钉钉打卡成了我生活中不可或缺的一部分。然而，有时候这个看似简单的任务却给我带来了不少烦恼。 每天早晚，我总是得牢记打开钉钉应用，点击"工作台"，再找到"考勤打卡"进行签到。有时候因为工作忙碌，会忘记打卡，导致考勤异常，影响当月的工作评价。而且，由于我使用的是苹果手机，有时候系统更新后，钉钉的某些功能会出现异常，使得打卡变得更加麻烦。 另外，我的家人使用的是安卓手机，他们也经常抱怨钉钉打卡的繁琐。尤其是对于那些不太熟悉手机操作的长辈来说，每次打卡都是一次挑战。他们总是担心自己会操作失误，导致打卡失败。 为了解决这些烦恼，我开始思考是否可以通过编写一个全自动化脚本来实现钉钉打卡。经过一段时间的摸索和学习，我终于成功编写出了一个适用于苹果和安卓系统的钉钉打卡脚本。
