输入原图一般是16:9,缩放形变小。crop是原图正方形,之后resize训练,坐标都是按比例的,影响不大,而且320x240推理速度还快点。

测试的时候输入是16:9的然后resize成320240,训练的时候等于是1:1的resize成320240,等于训练和测试的时候输入分别是1:1和16:9,感觉这个形变还是很大的吧

有一定的形变,但是h/w=1 的几率是很小的,你也可以认为这边几乎没做randomcrop来加强大人脸检出,反而一定程度上可以略微加强鲁棒性。也改过其他的纵横比,效果差不多甚至更差一点,其他纵横比形变不见的小,当然你可以试下2/3<w/h<3/2的比率或者输入变为320x320正方形训练,不过这样计算量要大30%,精度应该会提升一点。
