    参数1：image--待检测图片，一般为灰度图像加快检测速度；

    参数4：minNeighbors--表示构成检测目标的相邻矩形的最小个数(默认为3个)。
            如果组成检测目标的小矩形的个数和小于 min_neighbors - 1 都会被排除。
            如果min_neighbors 为 0, 则函数不做任何操作就返回所有的被检候选矩形框，
            这种设定值一般用在用户自定义对检测结果的组合程序上；
    参数5：flags--要么使用默认值，要么使用CV_HAAR_DO_CANNY_PRUNING，如果设置为
    CV_HAAR_DO_CANNY_PRUNING，那么函数将会使用Canny边缘检测来排除边缘过多或过少的区域，因此这些区域通常不会是人脸所在区域；
    参数6、7：minSize和maxSize用来限制得到的目标区域的范围。
