利用机器学习方法（分类）实现静态场景下的测试车辆检测 利用C语言或者Open_CV库，或者是MATLAB软件编写实现静态场景下的测视车辆检测。
需使用机器学习方法。
代码可以通过一个主函数直接运行出实验结果。
 Data文件夹中包含train_34x94（训练集）和test（测试集）两个文件夹。
其中，train_34x94文件夹中的数据用于训练模型，包含pos文件夹（内有550个正例样本）和neg文件夹（内有500个负例样本）；
Test文件夹中的数据用于测试。
 在Test测试集中的总体检测性能的评价指标为Recall、Precision和F-measure，写出对算法的性能评价和对实现中遇到问题的理解。

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。
