代码段augmentations.py：412～416行
centers = (boxes[:, :2] + boxes[:, 2:]) / 2.0
m1 = (choice_box[0] < centers[:, 0]) * (choice_box[1] < centers[:, 1])
m2 = (choice_box[2] > centers[:, 0]) * (choice_box[3] > centers[:, 1])
mask = m1 * m2#是否包含某个box的中心点 #这个保留face box的依据带考究只要中心点
在sample_boxes中就保存
current_boxes = boxes[mask, :].copy()
通过判断源face box的中心点是否在crop区域来确定该box是否保留？这个原则是否会出现一些box中人脸占比很少的情况？
