输入可以设置成320或者更小试下。

非常感谢!设置为320完全没问题!

你好,请问您出来的结果稳定吗?我现在训练的结果测试图片容易丢帧和回归效果不准确的情况。 @Belinda-great @Linzaer

@summerwbb 网络类型?训练输入大小?和提供的预训练模型效果差别大吗?测试时输入多大?如果测试图片人脸很多很小的话,适当减小候选框数值保证有效人脸。

我使用的RFB网络训练了一个人头检测模型(使用train_mb_tiny_RFB_fd.sh脚本,只改变了数据),训练和测试输入大小是640,测试时候选框改成了150个,是普通的电影素材。多数是不超过5个。请问我的loss应该降低到大概多少才是收敛了.

我也同时训练了320 版本,感觉640更适合我的场景。

用smooth_l1_loss,320x240训练人脸,200epochs最后大概稳定在2.84左右,640x480大概稳定在2.57左右,仅供参考。你数据集图片数有多少?很大可能和数据集数量和质量有关。你也可以尝试修改下预处理阶段的流程,比如加入Expand方法,扩张原图加强小目标能力,也可以略微修改randomcrop里的纵横比和交并比增强检测大目标能力。当然你也可以略微重复一两个不影响featuremap尺度的block加强网络主干。
