S$^3$FD: Single Shot Scale-invariant Face Detector

17 Aug 2017Shifeng ZhangXiangyu ZhuZhen LeiHailin ShiXiaobo WangStan Z. Li

This paper presents a real-time face detector, named Single Shot Scale-invariant Face Detector (S$^3$FD), which performs superiorly on various scales of faces with a single deep neural network, especially for small faces. Specifically, we try to solve the common problem that anchor-based detectors deteriorate dramatically as the objects become smaller... (read more)
