Feature Selective Anchor-Free Module for Single-Shot Object Detection

CVPR 2019 Chenchen ZhuYihui HeMarios Savvides

We motivate and present feature selective anchor-free (FSAF) module, a simple and effective building block for single-shot object detectors. It can be plugged into single-shot detectors with feature pyramid structure... (read more)
