您好,非常感谢您开源的模型。我现在想用您的模型进行人脸检测和关键点定位。但是我有一些问题需要请教,主要是关于下面这个函数:

[total_boxes points] = detect_face(img,minsize,PNet,RNet,ONet,threshold,fastresize,factor)

参数 minsize , threshold , ,factor 该依据什么准则进行设置?虽然您在demo里提供了一些默认参数,但是我并不知道您是根据什么来设置的。
再次感谢。

minsize根据实际情况设置。threshold根据你需要的准确率设。factor是性能与速度的权衡,0.709应该比较好。

@kpzhang93 谢谢。那threshhold里的值越大检测的结果越准确吗?您给的默认值是:

threshold=[0.6 0.7 0.5]

我感觉是threshold越大,false positive越少,但是漏检的会增多
