如果你在推理时的流程是检测,关键点,对齐,年龄识别,那训练时候就需要对齐裁剪,如果推理时不做对齐,那训练时候就不需要裁剪,两者保持一致。检测时候用那个检测网络,年龄识别的人脸数据就用那个网络去做预处理。 |
@vicwer 如果不对齐的话,效果是不是差一些呢? |
如果对齐了的话,那么您所提到的3个尺度是不是就不太适用了呢?一般对齐会紧贴着头进行裁剪,如果这样的话,需要预留一些空边。 |
对齐之后裁剪之前扩充 |
我觉得对齐会对性能有影响。原论文对齐之后裁剪三个尺度,保证人脸一定会裁到,而不对齐只 center crop 的话,就未必了。 |

作者,您好,请问您在训练数据时,有没有采用MTCNN 或者 Retinaface对人脸数据进行对齐裁剪呢?
期待您的回复,谢谢。
